Outotec to help expand JSC Stoilensky GOK iron ore pelletising plant

Outotec says it and Russia iron ore pellet producer JSC Stoilensky GOK (S-GOK), which is a part of NLMK Group, have entered into a contract to expand S-GOK’s pellet plant located in Stary Oskol, Russia.

The approximately €15 million ($16.9 million) order has been booked in Outotec’s 2019 March quarter order intake, it said.

Outotec previously delivered the technology for S-GOK’s pellet plant, which has been in operation since 2017, but this latest contract will see the plant’s annual capacity go from 6 Mt to 8 Mt.

Outotec will be responsible for the engineering, supply of key equipment and automation system as well as advisory services for installation and commissioning of the expansion.

The company said its latest technology improvements in green pelletising, cooling air process, and pallet car changing system will be applied, together with a digital solution package. The deliveries will take place at the end of 2020.

Additionally, in 2019-2021, NLMK said it plans to boost ore production and beneficiation capacity by 14% via upgrades of Stoilensky’s other transformation stages with a view to ensuring stable supply of raw materials to the pelletiser after it reaches the output of 8 Mt/y. This will enable the company to increase its ore processing capacity from 37 Mt/y to 42 Mt/y and to increase its concentrate output from 17.3 Mt/y to 20 Mt/y.

Kalle Härkki, Head of Outotec’s Metals, Energy & Water business, said: “We are excited about continued cooperation with S-GOK and the delivery of our latest technology improvements and digital solutions to this project. With intelligent services, applications and equipment we ensure safety, predictability and optimal performance of the plant, and S-GOK will get the best value from their assets.”

Konstantin Lagutin, NLMK Group Vice President, Investment Projects, said Outotec was its long-standing and reliable partner, “with whom we successfully implemented Europe’s largest pelletising plant in Stary Oskol”.

“The new expansion project is an important element of our Strategy 2022, aimed at meeting our growing raw material needs as well as increasing efficient steel production,” he said.

FMG sets up Future of Mobility Centre in WA, starts autonomous light vehicle trial

Fortescue Metals Group has announced the establishment of a research and development centre based in Karratha, Western Australia, to explore opportunities for the application of autonomous mobility technology in an urban environment.

On top of this, it said it had commenced an autonomous light vehicle trial at its Christmas Creek iron ore operation in the Pilbara of WA.

In partnership with the local community, City of Karratha and technology and research partners, the Fortescue Future of Mobility Centre will “leverage the company’s success in using autonomous technology across its operations”, FMG said.

Fortescue’s Chief Executive Officer, Elizabeth Gaines, said that innovation and emerging technologies, like autonomy, present an opportunity to work closely with the community to bring about mutual benefits.

“We are at the forefront of this technology with our mine operations set to become the first in the world to be fully autonomous and our fleet having safely travelled over 26 million kilometres since the first autonomous truck was introduced in 2012,” Gaines said.

“We are now building on our autonomous capability with the commencement of an autonomous light vehicle trial, at our Christmas Creek mine.

“The emergence of autonomy is one aspect in which our world is changing rapidly, and we intend to be part of the opportunities that it will represent for the mining industry, local communities such as Karratha, and beyond.”

By establishing the Fortescue Future of Mobility Centre in Karratha, FMG will have the ability to develop, test and trial this technology, Gaines said. This will further contribute to “Western Australia’s position as a world leading autonomous hub”, she added.

“We’ll be exploring all facets of the future of mobility including software, hardware and various forms of mobility solutions, to see where the opportunities lie,” she said.

City of Karratha Mayor, Peter Long, said: “I am delighted that of all the potential locations around Australia, Fortescue has selected Karratha as its base to develop this exciting and innovative new technology.”

Dr Fang Chen, Executive Director Data Science at The University of Technology Sydney, which will be a leading research provider to Fortescue’s work in autonomous technology, said: “Research into new technology and infrastructure will accelerate innovative mobility solutions to accommodate growth and future demands.”

Metso reduces downtime and improves safety in Kumba Kolomela crushing circuit

Kumba Iron Ore’s Kolomela mine in South Africa has reduced crusher liner replacement downtime and improved safety using a concave carousel and removal trays system provided by Metso, the mining equipment manufacturer reports.

Located in the Northern Cape Province, Kolomela contacted Metso for assistance in reducing its primary gyratory crusher concave liners replacement time.

The mine produces over 13 Mt/y of iron ore and is one of Kumba’s (majority-owned by Anglo American) largest operations in the country.

In mineral processing, crusher efficiency can be compromised over time, affecting production time and, most importantly, the safety of employees, Metso said. A major factor affecting crusher efficiency is the amount of downtime. The longer it takes to replace the wear parts inside the chamber of a primary gyratory crusher during a maintenance shutdown, the less uptime and, thus, less production. By reducing the number of lifts, the replacement can be done much faster and safer, according to Metso.

Kolomela approached Metso’s expert team to help it reduce the average downtime the operation encounters when replacing concave liners of their Superior SG60-110 primary gyratory crusher.

Metso’s Regional and Technical Support Manager Crusher Wears, Andrew Stones, said: “When the mine approached us with a request to help them speed up the process of changing the concave liners on the primary gyratory on site, they asked us to replicate the methodology that we once used at one of Anglo American’s major copper mines in South America, Los Bronces, which included the use of special tooling such as carousels and removal trays to remove the liners.

“Following the review of the Los Bronces system, we identified that we used different parts and installation methods not suitable for Kolomela’s operating model.”

Metso’s team looked at an alternative solution not only for different fixing arrangement on the carousels, but also changed parts. Instead of the mine having six rows of concaves to install, Metso reduced the rows to four. This minimised the installation time, according to Metso.

In addition to this, the team supplied Kolomela with removal trays – which enable a faster removal of the worn segments – as well as with modified attachments to help lift and install the carousels.

Metso’s solution has reportedly halved the downtime required for a concave liner change, but reduced downtime was not the only value add provided; the mine also reduced the injury exposure rate by 95%, according to the company.

Metso said: “Unlike the previous system that the mine used, which required people to be in the crusher when lowering each concave, Metso’s innovative carousel system provided optimised operating labour and safer installations. It is not dependent on human interaction.”

Kolomela’s Section Manager Engineering, Pieter Malan, said: “At Anglo American, we are unconditional about the safety of our colleagues. When the Metso team highlighted the safety element that the carousel methodology brings, it was indeed an added benefit and advantage. We understood, at that point, that Metso will also prioritise the safety and well-being of all individuals. There is no price on safety.”

Metso’s Vice President Mining, Africa and Middle East, Qasim Abrahams, said: “Previously, the Kolomela mine used 288 lifts to remove and install each concave liner; a process that has been identified as potentially hazardous work for the liner replacement team. Our new concave carousel concept reduced the lifts to 16, substantially improving both uptime and safety. The carousel allowed an entire tier of new concave segments to be lifted in place at once.”

Metso’s relationship with Kolomela was established in 2010, when the company provided the mine with the installation and commissioning of its crushers and the supply of original equipment manufacturer spare and wear parts. Other Metso equipment on site include two MP800 cone crushers and one MP1000 cone crusher.

Metso said: “The removal trays and carousel systems can be used on any primary gyratory crusher – Metso or third party.”

While this was a known and tested concept, this project required a completely new carousel and removal tray design and also new wear parts which included new concave liner design, patterns and trial castings, according to Metso.

Metso’s team of experts completed this project in six months, from customer order until delivery.

Drones continue to make mining activities safer, Anglo American says

Anglo American, in its 2018 annual report, says its use of drones for safety, surveying and security is continuing to expand as it looks to remote-control more of its mining activities.

The company has used drones attached to manned aerial-reconnaissance planes for many years and, today, considers itself an industry leader when it comes to drone use.

Anglo said it has an expanding fleet of drones, from fixed-wing aircraft to quadcopters, with about 50 skilled operators and another 30 people working in drone maintenance across the group. This is spread across its platinum group metal operations in South Africa, the Kumba iron ore mines (also in South Africa), and at De Beers diamond asset sites in Canada, Namibia and South Africa.

“Drones are an important part of our drive to remote-control many of our mining activities while gathering enhanced data and real-time operational performance metrics,” Anglo said. “They provide rapid visual access and multiple views, with smaller drones being used to inspect confined spaces on mines and in processing plants, while bigger aircraft are able to fly at night and stay aloft for up to eight hours.”

Drones are being used in varied tasks such as exploration, mine mapping and calculating the volume of stockpiles, Anglo said, adding that they are proving to be cost effective.

“The deployment of drones is assisting in making our activities safer. Crucially, their use avoids the need for people in potentially hazardous areas,” the company said.

Drones are now being used to inspect and monitor high-risk areas, including stockpiles, mine slopes, ore passes, tailings dams and chemical-storage facilities, Anglo said. They can check for the presence of personnel in a blast area, and measure fragmentation or the direction of dust movement after a blast. By employing them in such applications, it removes the possibility of Anglo personnel entering dangerous areas.

Other applications the company is using them on include traffic management at operations, as well as monitoring rehabilitation activity, including in areas where it can be difficult and risky for people on the ground to gain access.

Frans Kruger, Anglo American’s Global Aviation Safety Principal, said: “Drones increase our safety and efficiency, and they let us take human beings out of potentially dangerous environments.”

Anglo concluded: “Drone technology is evolving fast and, as a responsible operator, we are working closely with other drone operators and South Africa’s Civil Aviation Authority, for example, to develop appropriate standards, while also serving with other mining companies on the technical advisory committee of the Flight Safety Foundation.”

Civmec to help modularise BHP’s South Flank iron ore mine

Civmec says it has signed a contract with BHP that will see the ASX-listed engineering company fabricate and modularise key components for the under-construction South Flank iron ore project, in the Pilbara of Western Australia.

The award of the South Flank module fabrication and assembly package #3 covers the supply and assembly of 23 fully-equipped ‘smart modules’, including the supply and installation of the required mechanical and electrical equipment up to no-load commissioning for each module, Civmec said. The scope comprises conveyor shuttle modules, sample station, pump skids, train loadout and feeder modules, all of which will be fabricated and assembled at Civmec’s facility in Henderson, Western Australia, before being transported to site for installation.

Work will commence immediately, with completion anticipated by mid-2020, according to Civmec.

Civmec’s Chief Executive Officer, Patrick Tallon, said: “We are extremely pleased to be given this opportunity to further support BHP in the delivery of what will ultimately become its flagship mine. The award of this scope of work complements the packages already in production for thyssenkrupp, in the supply, manufacture, trial assembly, surface treatment and pre-assembly of stackers, bogies and equalisers for the rail mounted machines for the South Flank project.”

When fully operational, South Flank will be one of the world’s largest iron ore operations integrating the latest advances in autonomous-ready fleets, digital connectivity and modular design, Civmec said.

BHP is targeting first ore extraction at the operation in 2021 and expects to ramp up to 80 Mt/y of output. This will replace production from the existing Yandi mine, which is reaching the end of its economic life. The company carried out the first blast at the project in September.

The combined value of these packages for South Flank is around A$48 million ($34 million).

BHP looks at phased rollout of autonomous trucks at WA iron ore ops

BHP CEO, Andrew Mackenzie, says the diversified miner is looking at a phased roll out of autonomous haulage technology across its Western Australia Iron Ore operations following success at its Jimblebar mine.

BHP opened Jimblebar, located 40 km east of Newman in the Pilbara, back in 2014 and soon started using it as one of the main testbeds for autonomous trucking technology. The site went fully autonomous at the end of 2017.

Mackenzie said in the company’s half-year (to end-December) results presentation that Jimblebar’s fully autonomous trucks were now “amongst our safest and most productive”. He added: “This success will guide a phased roll out across other operations.”

In terms of automation, the company also said it was studying the use of autonomous drills at its majority-owned Escondida copper mine in Chile, in addition to carrying out further trial integration and automation technologies at its Eastern Ridge Innovation Mine.

NRW books A$62 million of business with FMG for Eliwana rail project

NRW has been formally awarded the contract for Stage 1 earthworks, roadworks and drainage works of Fortescue Metals Group’s Eliwana Rail project in Western Australia.

The contract, which has a final value of around A$62 million ($44 million), follows the ASX-listed contractor being selected as the preferred contractor for these works at the end of last year.

The overall Eliwana mine and rail project is expected to cost $1.275 billion to build, and include 143 km of rail, a new 30 Mt/y ore processing facility (OPF) and infrastructure. Production is slated for December 2020 with a life of mine strip ratio of 1.1.

The project underpins the introduction of a 60% Fe grade product (Fortescue Premium) in the second half of the mining company’s 2019 financial year.

MineSense front and centre in bulk ore sorting game

Having just commercialised its bulk ore sorting technology at Teck Resources’ Highland Valley Copper (HVC) operations in British Columbia, Canada, MineSense is looking to show the wider industry just how effective this pre-concentration process can be.

IM spoke with President and CEO, Jeff More, to find out more about the company’s ShovelSense and BeltSense technologies and how the Vancouver-based startup has been able to secure investment from the likes of ABB, Caterpillar and Mitsubishi.

IM: Can you explain in a little more detail how your ShovelSense and BeltSense solutions work?

JM: The base technology for both is X-ray Fluorescence (XRF) – a technology that has been around for some time. What we have done to this existing technology, which is quite unique, is three things:

  • One, we have extended dramatically the range of XRF. Traditionally XRF would almost have to be held to the surface of a rock to get accurate measurements. The range extension allows us to work in the shovel environment where we are working across metres of volume;
  • Second is speed. Our system is extremely fast. High speed analysis is required on our conveyor belt applications, but this is even more important in the shovel, where we’re measuring dynamically; as the material is flowing into the shovel, to get a representative reading, you have to be able to take very fast readings of the material as it is moving past the sensors;
  • The third is robustness. On a shovel, you are in a nasty environment from a shock and vibration perspective. We developed a system with sensitive components – the XRF itself, as well as the computing devices around it – that can stand up to that very high shock- and vibration-type environment.

IM: The most high-profile examples of the application of your ShovelSense technology have been at copper mines (HVC, in particular); is the detection technology particularly effective in these ores? Is it being trialled elsewhere?

JM: The current sensing we have with the XRF is very effective in a certain section of the periodic table, which nicely covers the major base metals. We’re focused on copper, nickel, zinc and polymetallic versions of those three. The fourth area of focus is iron ore.

We’ve selected copper as our first focus because of the size of the market and the geography. We have done most of our work in copper, but we now also have operating systems in nickel and zinc.

On a lab scale, the technology has been very effective in iron ore, but iron ore is a very different flow sheet, so we have purposely set it as our fourth market in what we call our primary clusters.

We have five mine site customers at the moment – three copper, one zinc-lead and one nickel-polymetallic.

We were very much focused on North America and, in particular, British Columbia for our first pilots and trials as it was quite easy for us to service in our back yard. The first international market was Chile, for obvious reasons in terms of copper production, and we now have a full MineSense entity and team operating in Chile and Peru.

We’re staggering the rest of our global expansion. We’re now quite active from a business development perspective in southern Africa – South Africa, Zambia, DRC – and have activity in Australia.

We have Systems installed at two different copper mines in British Columbia, one at a very large nickel-polymetallic complex in Sudbury, Ontario, and will have a fourth system operating in Alaska. We also have two mines, but four systems, operating in Chile. By the end of Q2, we will have another three systems operating in Chile.

We did all our development work for the system at Teck’s HVC operation and we’re now completely commercial there. We officially commissioned our first system in December, the second system is being commissioned as we speak and the third and fourth will be installed and commissioned in late-March. This will completely equip their fleet.

IM: Teck has previously said the use of ShovelSense has resulted in “a net measurable increase in the amount of ore (and the associated head grade)” it has available to feed its mill at HVC. Are these results in keeping with your expectations for the technology?

JM: Yes, absolutely. We base everything on, what we call, our value model. Very early in our engagement process, we set out a detailed model that calculates the profit improvement that mine will see – we did the same for Teck HVC.

We agreed on a target at HVC and are actually exceeding that estimate. Most importantly, Teck is also seeing that value and is estimating a great overall impact at that mine.

This is an abridged version of a Q&A to be published in the ore sorting feature in the March issue of International Mining.

Vauramo looks to build on Metso’s mineral processing R&D culture

Pekka Vauramo might have only been away from the mining industry for just over a decade, but the new Metso CEO is acutely aware that the digitalisation and automation trend he saw the beginnings of during his time at Sandvik now plays a major role in planning the mines of the future.

Fortunately for Vauramo, a mining engineer by profession, he has come into this executive role at a very good time – Metso’s October-December quarter results showed an operating profit of €93 million ($105 million), or 10.4% of sales, and a 38% rise in orders received (in constant currencies) on the back of strong mining equipment demand.

IM met with Vauramo in London just after the financial results were published and asked him for his initial impressions of Metso, three months after joining from Finnair.

IM: As a group, what are the core commodities Metso focuses on?

PV: From a crushing viewpoint, it really doesn’t matter if it is iron ore, gold, copper, or nickel. Many of our customers are investing in copper right now – electric cars and battery metals are driving this. There are also ongoing investments in iron ore.

IM: What were your goals for Metso when you were appointed to the CEO role last year?

PV: The overall objective for Metso should be to grow the business. Metso has been standing still on its feet for quite some time. We have been profitable over the years and the focus has been on delivering black numbers even in difficult days; there is always value in this.

But, when looking at long-term R&D, which really lays the groundwork for organic growth, we have to increase our investments.

Metso reorganised itself during Nico’s (Delvaux, former CEO) time a year ago. The current organisation is, therefore, fairly young and, in the short term, we need to continue making sure we know what our responsibilities are within Metso and ensure we don’t lose sight of our customers. Several of our businesses have common customers and we need to be able to deliver one Metso experience.

My approach coming into the role was to validate where we are with the current way of working. My conclusion is that right now, no bigger changes are needed. We will, obviously, finetune as we go. Also, when we look at the latest results, we have no reason to change!

IM: Speaking of change, how would you say the mining equipment market has evolved since you were last at Sandvik?*

PV: Technology plays a certain role – the industry talks more about automation and we do see more automation. I was involved very early on with automation in the Sandvik days, introducing the automated underground loaders, and can still remember when we carried out the first trials. It is becoming, maybe, not the norm yet, but every new mine has the option to automate.

Then, of course, with the automation capabilities, the question is: where are the people operating or overseeing these machines? Do they have to be on the mine site, or can some of them be elsewhere? Next, it is about how much data can be obtained from the equipment and what value can be gained from the data.

Also, consolidation has happened in the business. Some of the mining companies are no longer around and bigger ones have got bigger. This junior activity in mining has been an interesting and exciting part of the business – it is still there, perhaps not to the same extent, but there are also some new names.

We see also China investing in Africa on a bigger scale. They had their first investments in Zambia when I was with Sandvik and now it owns many more mines there. Chinese companies are also in South America; it has become a much more international field.

IM: I have seen a few interviews talking about Metso’s R&D spend and how the 1% of turnover investment figure is inadequate. What do you see as an adequate % of turnover to invest? How quickly can Metso reach this level of investment?

PV: I think Metso needs to double that. But this takes some time; it is not just about money, it is about the capability and the R&D culture within the company. We have that culture, but we need to expand it. We are ramping it up – we have added more than €10 million ($11.3 million) in R&D last year and are planning to add another €10 million this year.

Also, besides the traditional R&D, we will continue to invest in digitalisation. We currently put more than €10 million into that and I’m quite sure we need to put more money into in it, too.
Currently R&D and digitalisation are in slightly different ‘boxes’, but as long as they are delivering something that helps customers to do better business, then it is all considered product development.

IM: Do you think mining companies are fully realising the potential value these digital solutions can have within their operations?

PV: Every company is doing something by itself, but where I see the industry is partially holding back is that some of the customers think this data is something they own – and rightly so.

However, I think companies like Metso could, let’s say, put some algorithms on top of the data and add value by comparing data from other places and share the relevant results with those participating without telling the secrets of others.

If I look at what other manufacturers have done over the years, it is evident that the industry is moving in this direction. From the end users’ viewpoint, it can be somewhat complicated because companies make different choices on technology and all these technologies need to be interfaced somehow into similar formats. Currently, this might be an issue as there are not really strong enough standards in the industry – yet that would help people streamline things and concentrate on the data.

IM: Will Metso’s future focus be on organic growth from R&D, as opposed to the M&A activity?

PV: There is value in both strategies, but the R&D activity is something that companies need to do continuously. In a business that is cyclical – mining being the most cyclical business we are in – those companies that invest organically in R&D during the downturn are the ones that tend to benefit most when the upturn starts. The ones that have their offering in good shape are the ones that win when it gets busy. That is also where Metso should be.

Acquisitions do play a role, but there are no easy answers there. We made several small acquisitions last year and we will continue with this. New acquisitions can be related either to the service side of the business or technology.

IM: How has climate change and sustainability impacted the way Metso develops minerals processing technology?

PV: There has been a tremendous movement since the latest climate report was published last year. Now, everyone is rightly concerned about emissions. The mining equipment we talk about is primarily electrically driven. Energy efficiency is one of our focus areas. If we broaden the topic out to water, for example, we know some of the deposits are in difficult places where major parts of the investment go into desalinating and pumping the water to the mine site. So, becoming also more water efficient is something that will be critical for mining companies.

There are always moments that stop the industry to think about what can be done to prevent accidents from happening. Our deepest sympathies go out to the ones that lost their relatives or closest ones in the Feijão dam collapse. It will change how mining is conducted and there may be some technological developments which we, as a company, can take forward.

IM: Lastly, what parallels can you draw between the mining and airline industries?

PV: They are somewhat distant industries, but both are fairly specialised; mining is something people very seldom go into just like that. You can acquaint yourself with many other jobs or businesses by just walking around in that environment, but you don’t end up doing that in a mine or an aircraft. Yes, you travel in an aircraft, but there’s much more behind the cabin you don’t know about.

In these type of businesses, people need special training and need to be selected – not everyone can work in a mine and not everyone is qualified to fly an aircraft. Both are people businesses at the end of the day: even though the operations may be automated – aircrafts might fly with the autopilot and mines might be run by an autopilot – sometimes highly-skilled human intervention is needed.

A big part of the airline business is service. It’s a very fast cycle service business, which provides a good opportunity to learn about how service works. It’s a daily routine with people spending anything from half an hour to half a day on an aircraft. When the flight is over you get quick feedback. If you look at the mining business, some of the projects take two years to sell, two years to deliver and one year to start up. It’s a long, long cycle. But, you either like the service or you don’t like it.

IM: Do you have anything else to add?

PV: Just to say, on the results, I am very grateful to our customers for, first of all, trusting us with their business. I am also very proud of our people in all the countries we are in – and in many departments such as sales and service – who have done a great job over the past year.

Outotec continues to invest in technology as sales rise

Outotec registered a year-on-year improvement in financial performance in 2018, excluding a €110 million ($125 million) ilmenite smelter project provision, the company reported today.

The company’s sales increased 12% in 2018 to €1.28 billion, while its order intake jumped 4% to €1.25 billion. The €110 million provision for the Saudi Arabia project saw adjusted earnings before interest and taxes (EBIT) come in at -€46.2 million, compared with €33.5 million in 2017, yet President and CEO, Markku Teräsvasara, said adjusted EBIT would have almost doubled to €64 million had it not been for this deduction.

“In 2018, we made significant progress in several areas,” Teräsvasara said. “In the beginning of the year, the market for minerals and metals technologies improved, but global macroeconomic uncertainties and reduced metal prices started to affect the market sentiment, and we saw several larger investment decisions being delayed into 2019.

“This was demonstrated in our order intake, which increased 4% year-on-year (in comparable currencies 8%) but declined in the fourth (December) quarter from the comparison period,” he said.

The company’s largest order in the December quarter – around €34 million – was for the delivery of battery chemicals technology in Finland for the Terrafame plant to be built in Sotkamo. The company has since followed this up with a contract in Australia to convert spodumene to lithium hydroxide.

Teräsvasara said profitability continued to improve in the Minerals Processing segment, with EBIT coming in at €78.5 million, compared with €60 million a year earlier.

Outotec said copper, gold, and battery metals projects were the most active during 2018, with demand for minerals processing equipment and spare parts stable throughout the year. In the company’s Metals, Energy & Water divisions, meanwhile, “solid demand” was registered in hydrometallurgical and pelletising solutions, as well as sulphuric acid plants, Outotec said.

Outotec said the €110 million provision related to possible costs for an ilmenite smelter project in Saudi Arabia. Back in October, the company said it was working with the client to investigate the reasons why one of the repaired furnaces in a first-of-its-kind ilmenite smelter had issues starting up.

“The currently estimated provision is based on progress made with the analysis of the furnace,” the company said today, adding that the provision was booked in its December quarter results.

Teräsvasara highlighted the “leading technologies” that were part of the company’s core strength in the 2018 results.

During the year, the company continued to develop its technological capabilities and grow its patent portfolio, with Outotec’s R&D investments representing 5% of its sales and totalling €57 million last year, he said.

Outotec went into a little more detail about this in its 2018 and Q4 review.

The first two industrial references of Outotec TankCell® e630s are running at the Buenavista del Cobre concentrator in northern Mexico, the company said.

“The site has reported an increase of more than 3% in overall recovery with a higher-grade copper concentrate. The TankCell® e630 flotation cell has a nominal volume of 630 m³ and is equipped with a FloatForce mechanism with a diameter of 2,200 mm,” Outotec said.

The company has also developed and filed a patent application for a thermal leaching process to convert spodumene concentrate into battery-grade lithium hydroxide. The lithium hydroxide process has been piloted at the Outotec Research Center in Pori for Critical Elements Corporation in Canada and Keliber Oy in Finland. Lithium hydroxide corresponds to the change in demand in the metal salt markets, it said.

Meanwhile, the new Hybrid filter plates that are 40% lighter, and, therefore, more competitive than conventional plates, were introduced to the spare and wear parts markets during 2018, Outotec said. “The new plates also improve the filtration capacity, provide low residual moisture in the cake, and reduce operational costs,” it added.

Outotec has also designed a skid-mounted, modular prefabricated sulphuric acid plant which significantly lowers the installation cost and time. In addition, the modular plant offers lower operation costs, increased availability and maintainability, as well as environmentally sound and safe operation, it said. “The innovative plant concept is based on Outotec’s technology and expertise gained from 650 plants delivered globally,” Outotec said.

Meanwhile, Outotec is in the middle of a pilot study with Sweden-based miner LKAB to treat industrial waters at its Svappavaara mine in the country. The pilot started in August and consists of nanofiltration and chemical precipitation of sulphate with Outotec’s Ettringite process. The pilot has shown sulphate concentration can be significantly reduced from the inlet value of 1,800 mg/l to the level of 150 mg/l, Outotec said.

A new digital product, Outotec Health Indicator, was also introduced last year. This produces data for flotation process control when used together with Courier on-stream elemental analysers. It enables higher performance in terms of concentrate quality and recovery of valuable minerals, according to the company.

Lastly, Outotec has been developing MesoTherm™ bio-oxidation technology for leaching base metals. The development work has shown it to be effective on certain copper sulphides, yielding 98% copper dissolution.
