As ore grades continue to decline in the mining space, FLSmidth says its expertise in mineral sampling and laboratory automation is becoming increasingly valuable to mines.

“The more you understand about the characteristics of the ore entering your process plant, the better you can treat it,” Martin Matthysen, Director, SPA (sampling, preparation and analysis), Sub Saharan African and Middle East at FLSmidth, said. “But this needs technology that can sample high volumes, maintain rapid turnaround times and deliver quality results.”

Only then can plant operators respond to laboratory data in real time, which is one of the keys to effective plant optimisation. With over 30 years of experience, FLSmidth has been a pioneer in laboratory systems integration, as well as driving automation in the laboratory environment, it says.

“Our particular expertise in laboratory automation is now recognised worldwide,” Matthysen said. “This is why we have supplied 95% of all automated laboratories to the global mining industry constructed over the past dozen years or so.”

This automation expertise was bolstered last year when the company completed the acquisition of IMP Automation Group, a global leader in automated laboratory solutions for the mining industry. Included in the transaction was IMP’s 50% share in a joint venture which provides complete operations and maintenance-based solutions for automated labs, the company said.

FLSmidth’s offerings address all stages of a mines’ sampling and analysis requirements. It designs solutions for exploration and ore characterisation, grade control, process plants and port shipment. The highest quality equipment is sourced and applied to a laboratory solution to achieve accurate sampling, effective sample preparation and detailed sample analysis, the company says.

Each laboratory design is unique, Matthysen says, as it must suit each customer’s operating conditions and strategic goals. The design process, therefore, demands close collaboration with the customer and a detailed examination of mined material and process demands. This ensures the laboratory generates exactly the type of analytical data the plant operators require.

“With our world-class mineral research and testing facilities, we are constantly pioneering innovations that add value to customers,” he says. “Our automated solutions also offer consistency and traceability, while improving ergonomics and eliminating hazards to laboratory personnel.”

Among the company’s innovations has been an environmentally friendly methodology that replaces traditional wet chemistry. With no acid being used to dissolve platinum ore, for instance, the process produces no toxic waste – dramatically reducing the impact on the environment, according to FLSmidth.

“We are accredited in terms of international quality standards, and work strictly to our customers’ stringent specifications regarding health, safety and environment,” Matthysen says. “Our expertise gives customers the confidence not only to procure laboratories from us, but increasingly to contract us to maintain and operate those facilities on their behalf.”

Karara Mining to stack tailings high to keep costs, water use and footprint low

Bis, FLSmidth and Karara Mining have developed a “unique mobile stacking conveyor” solution that has cut water use, costs and the environmental footprint at the iron ore miner’s operation in Western Australia.

If Karara’s iron ore mine had chosen a wet tailings storage facility, the tailings pond would have been roughly 8 sq.km based on its 30-year mine life, according to FLSmidth.

The operation is also in the Mid-West region of Western Australia, an area with scarce water reserves, so losing so much water to wet tailings would have been costly to both the environment and Karara’s bottom line.

With these factors in mind, Karara looked at implementing a dry-stacked/filtered tailings system to allow for significant water recovery and reuse. As well as reducing costs, dry stack technology would reduce the tailings footprint to around 4 sq.km, according to FLSmidth.

Bis worked with Karara and FLSmidth to develop a solution to build, own, operate and maintain a “unique mobile stacking conveyor”, FLSmidth said. This fixed infrastructure solution was developed by the three companies to integrate a walking conveyor and stacking technology normally used in large-scale copper mining operations.

Aside from the significant reduction of the physical footprint compared with the wet tailings alternative, Karara was looking for cost efficiencies in other areas, FLSmidth said. “For instance, the planning of a wet tailings storage facility needs to factor in an ongoing maintenance strategy. This comes with a perpetual cost that can only be guessed at while the decades pass,” the company said. “With dry-stack tailings, the total cost of ownership over the mine’s lifetime is easier to estimate and Karara were confident the dry stack solution would be cost competitive.”

Water usage was another key consideration for Karara. With environmental and cost factors in mind, Karara wanted to look at ways to have greater control over water assets on site. The ability to reuse and recycle water in the mining process would lead to substantial cost efficiencies by minimising the amount of makeup water needed for the mining operation, FLSmidth said.

The technology implemented into Karara’s tailings storage facility was also an important factor as Karara wanted the flexibility to continually update the equipment with the view of running it more efficiently as new technology became available. It engaged Bis to operate the facility machinery based on its deep industry experience with materials handling and bulk logistics, FLSmidth said.

FLSmidth, meanwhile, was identified by Karara as being able to meet the project’s requirements and mine-specific needs.

The mining OEM said: “A primary demand was the ability to supply a cost-effective dry stacking technology ideal for dry climate mining operations that reduced water requirements. With FLSmidth’s advanced stacking capability (machinery working off stacked pile) and ability to stack tailings at 15% moisture content, this meant tangible water savings for Karara.

“At Karara, the dry tailings will be stacked in four lifts to the maximum height approved by the Western Australia Government. The solution proposed by FLSmidth also created a smaller tailings storage footprint, which also meant improved site rehabilitation potential.”

Karara worked closely with Bis and FLSmidth to get the project off the ground and make Karara the first mine in Australia to take full advantage of this dry-stack technology, FLSmidth said.

The tailings storage facility is fast approaching the completion of Lift 1 and, together with Karara, Bis and FLSmidth are already in the planning stage to lift the equipment to the second level.

FLSmidth stresses service capability as mines focus on productivity

Optimising customers’ production and maximising their return on investment is the ongoing mission of FLSmidth’s warehousing facility in Stormill, west of Johannesburg, South Africa, the company says.

According to Derek Lane, Operations Manager at FLSmidth, continued investment in the facility over the past decade has kept it at the leading edge of customer service. Today, it has grown to 10,500 m² under roof and 1,660 m² under crane, with dual lifting capacity of up to 40 t.

“We have technical capability across FLSmidth’s range of KREBS® slurry pumps, cyclones and valves,” Lane says, “allowing us to service customers through sub-Saharan Africa and into the Middle East.”

Meeting customer needs is paramount, and the operation has a strong focus on stocking strategic parts to facilitate the rapid assembly of new product. In addition to this, and central to the pump operation, is also the efficient refurbishment and retrofitting of equipment. Supporting the customer drive for lowest total cost of ownership, the Stormill facility also stocks a range of service exchange units assisting mines to maintain uptime.

Strategic stocking is done on the full range of KREBS pumps from the UMD™ heavy duty, millMAX™, split casing slurryMAX™, gravelMAX™ and vMAX™ range, all of which feature a recessed impeller design allowing the pumps to run dry. In addition, Technequip™ valves are stocked in a variety of sizes, both flanged and wafer type.

“Our workshop and warehousing capacity equip us to respond quickly to customers in various regions of Africa and beyond,” he says. “This is critical in helping maintain their operational uptime while keeping costs down.”

The quality of the FLSmidth’s KREBS pump range also allows them to be offered to customers on a trial basis. Trial pumps can be run against time or tonnage targets to ensure that they exceed the performance of existing equipment, Service Manager, Martin Jones, says.

“The service component in these trials includes a dedicated service technician who visits site for checking and fine-tuning during the trial,” he said. “This level of technical on-site collaboration from our teams allows operational parameters to be closely monitored and refinements made to specific performance requirements.”

An important cornerstone of FLSmidth’s customer support strategy is closely aligned with the operational drive by mines to achieve the lowest operating costs possible. Jones says that by providing a range of service support options for all new products supplied, the company is able to add value to mine sites. Within South Africa, service support options include regular visits by service technicians to site, as well as more intensive levels of service in the form of bespoke maintenance contracts, and field service support teams operating in strategic locations.

“Some customers request a period of commissioning assistance, for example, and we can provide experts on site for as long as the customer requests them,” he says.

Lane highlights the importance of regular and correct maintenance of equipment to minimise lifecycle costs and maximise productivity. To meet this goal, FLSmidth conducts customised training on request for customers. This could be focused on hands-on maintenance staff dealing with essential day-to-day maintenance. It is also available for higher-level staff such plant engineers, on topics such as product selection. The training can even be delivered in different languages suited to the region.

The large stockholding of spares at Stormill for pumps, cyclones and valves is based on historical and forecasted customer consumption. Key customers also hold strategic consignment stocks at their sites. These are currently located in Zambia, the Democratic Republic of Congo and Tanzania, as well as with an agent in South Africa’s Northern Cape Province.

“This allows us to have the stock as close to the customer as possible, to optimise availability,” he says.

He emphasised that all the Stormill facility’s activity is strictly governed by recognised international standards. The operation is certified with ISO 9001 for quality, ISO 14001 for environmental management and OSHAS 18001 for safety and health.

FLSmidth says it has acquired the assets of Mill-Ore Industries Inc, increasing its level of service for customers in the mining-rich hub of eastern Canada.

The acquisition, which includes facilities and equipmen, will see all Mill-Ore employees transfer to FLSmidth.

FLSmidth said: “Miners in eastern Canada can now expect faster, personal and local service, with support provided in French and English. This move is part of our commitment to increase the level of service for French-speaking customers and to streamline our overall service process.”

The company said it had, for a period, been evaluating local service units in eastern Canada, with the target of growing business and improving customer service. Mill-Ore Industries, which was an important Canadian service centre for KREBS® pumps and cyclones, was chosen as the ideal acquisition, it said. “It will continue to provide the same high level of service customers have associated with Mill-Ore Industries, but will operate under the new name of FLSmidth Service Center, Eastern Canada,” the company explained.

In the coming months, additional services will be rolled-out to increase the service capabilities available through the centre.

FLSmidth to boost plant efficiency with SmartCyclone system

With process plant optimisation techniques becoming a necessity for mines looking to maximise their operating performance by keeping costs low, throughput high and downtime to a minimum, FLSmidth has devised an automated monitoring and control solution for reducing cyclone-related process deviations.

The SmartCyclone™ system delivers in all three areas for cyclone circuits, according to the company, improving cyclone overflow particle size distribution, predicting and controling cyclone maintenance schedules, and optimising closed-circuit grinding processes.

FLSmidth said: “This equates to monitoring the performance of individual cyclones within a circuit in real time, preventing unplanned breakdowns from occurring and monitoring wear rates while ensuring the cyclones are operating optimally at all times. This translates into higher efficiencies in the plant and ultimately, higher profitability.”

The SmartCyclone closed circuit grinding optimisation system combines a variety of FLSmidth patented technologies, including the FLSmidth Krebs SmartCyclone wear detection sensor technology and the Krebs’ patented roping sensor technology (with patent-pending wireless controller system). This technology immediately identifies if a cyclone is malfunctioning, the company said.

The closed circuit grinding optimisation system also incorporates FLSmidth’s ECS/ProcessExpert® process control software with a new patent-pending SmartWear™ cyclone maintenance algorithm.

One of the largest benefits associated with this software is the ability to develop a uniform operation strategy that outlines the best way to run the plant, according to FLSmidth. “Once this strategy has been established, the necessity to train new operators is reduced.”

Reducing or eliminating manual operation, which decreases the potential for human error, is also one of the overarching benefits of SmartCyclone, the company says.

FLSmidth has more recently enhanced its Krebs SmartCyclone system with wireless technology that
enhances installation by eliminating the need for individual nodes and the interconnecting cables between the sensors and nodes and associated controllers.

It uses a central wireless controller that can handle up to 16 sensors per unit; providing real-time wireless detection and communication of roping and/or wear data. The new wireless controller unit is a handheld device that can be removed from its docking/charging station to sync the individual sensors. Once removed, it goes into battery-power mode and the user can walk to a desired sensor, activate it with a magnet, trigger and set the necessary operating parameters.

FLSmidth FerroCer wear panels increase uptime at Hindustan Zinc operation

FLSmidth’s FerroCer® Impact wear panels have proven their worth in the mineral processing circuit at Hindustan Zinc’s Rampura Agucha operations in Rajasthan, India, having significantly outlasted the previous manganese liners the lead-zinc mine was using.

By the end of 2018, the mine couldn’t say exactly just how good FerroCer wear panels were as they were still in place over a year since installation.

However, by March 2019, it was confirmed the FerroCer liners had completed about 480 days (16 months approximately) in operation and had withstood some 2.45 Mt of lead-zinc ore conveyed through the U-13 tripper chute, located after the primary crusher at the mine.

This is a significant improvement on the previous 40 mm-thick manganese steel liners, which had a life span of only 23-25 days, according to FLSmidth.

The constant wear on these liners meant the material handling system needed to be frequently shutdown so the worn-out liners could be replaced with new manganese steel liners, which weighed about 50 kg each.

“Because of the elevated location of several chutes, replacement of the liners required safety preparations (such as scaffolding and other access and handling arrangements), with five to six workers required to get inside the chutes to handle the liners,” FLSmidth said.

FLSmidth visited officials at the Rampura Agucha mines in June 2017 and recommended FerroCer wear panels to address the high wear issues in the material handling chutes.

“Each panel comprises a set of abrasion-resistant ceramic inserts enclosed in a matrix of malleable steel, which ensures only the top surface of the insert is exposed to material impact,” FLSmidth said. “The sides of the inserts are tapered within the matrix, keeping them in place and preventing material particles and fluids from damaging the panels.”

Some in-situ results from the 220-day mark showed the wear on the panels measured only 8-10 mm and had withstood around 1.5 Mt of lead-zinc ore conveyed through the U-13 tripper chute.

“This means FerroCer outlasted the previous panels by over 10 times, meaning a much longer replacement cycle,” FLSmidth said.

Clearly delighted with this outcome, Hindustan Zinc is now looking to use FerroCer impact wear panels across its high-impact wear locations, according to FLSmidth.

Praveen Bhardwaj, Assistant General Manager (Mechanical), HZL – RA Mines, Rajasthan, said: “FerroCer has reduced maintenance time due to the much longer replacement cycle, eliminated possible damage to the mother plate and spillage of material due to the highly abrasive nature of ore, and significantly reduced safety hazards. HZL intends to install FerroCer impact wear panels in all the high impact wear locations.”

The results at the Hindustan Zinc site follow on from results from two mines in Australia. One mine operated for more than a year without replacing its wear liners and the other site is on the same track, approaching its first year without the need for liner replacement.

Meanwhile, in a Peruvian copper mine, 24 smaller and lighter FerroCer panels, each made of steel plates with ceramic inserts, replaced six generic liners. After a total of 12.6 Mt passed, with a feed of 7,500 t/h, wear was no more than 3%, FLSmidth said.

“At that rate, FerroCer lasts at least 10 times longer than the most expensive and recognised wear liner on the market.”

Vista Gold Mt Todd PFS points towards use of ore sorting, fine grinding

Following extensive metallurgic test work carried out over the past year, Vista Gold looks like it has settled on a flowsheet for its Mt Todd gold project in the Northern Territory of Australia that includes ore sorting and the selection of the FLSmidth VXP mill as the preferred fine-grinding mill.

The company detailed this in an updated prefeasibility study (PFS) for the project, which factored in the results of metallurgical optimisation test work, a redesign of the fine grinding circuit, construction and ramp-up schedule changes and a comprehensive review of all aspects of the project.

The process improvements resulted in improved projected gold recovery and increased estimated gold production at Mt Todd, Vista Gold said.

According to the PFS, a 50,000 t/d operation at Mt Todd could see the operation produce 413,400 oz/y of gold over the 13-year mine life at average all-in sustaining costs of $746/oz.

The estimated initial capital requirement came in at $826 million, with the project offering an after-tax net present value (5% discount) of $823 million at a $1,350/oz gold price and a $0.70=A$1.00 exchange rate.

In the company’s metallurgy, processing and infrastructure section, it detailed the processing side of Mt Todd, saying that recent metallurgic test programs had confirmed the efficiency of ore sorting across a broad range of head grades and the natural concentration of gold in the screen undersize material prior to sorting. The company carried out such test work at TOMRA Sorting Solutions in Germany, where two-stage (X-ray Transmission and laser) sorting tests were completed using production-sized and commercially available equipment.

It also said such test work had confirmed the efficiency of fine grinding and improved gold leach recoveries at an 80% passing grind size of 40 microns, in addition to the selection of the FLSmidth VXP mill as the preferred fine-grinding mill.

The company previously sent samples to Core Metallurgy Pty to obtain fine grinding data simulating grinding in the horizontal IsaMill and to the FLSmidth Minerals Testing and Research Center to obtain data simulating grinding in the vertical VXP Mill.

FLSmidth reflects on KREBS slurry pump dominance in Africa

Equipment maintenance, Mineral processing, Mining equipment, Mining services, Water management, , , , , , ,

KREBS® slurry pumps have become leaders in mill discharge applications in Africa, with the latest Ultimate Mill Discharge (UMD) pump leading the way in these heavy-duty applications, according to FLSmidth.

Andre Hall, FLSmidth Regional Product Line Manager — Pumps, Cyclones and Valves, said: “West African gold mines and the copper operations of Zambia and Democratic Republic of Congo are among the areas where these robust pumps dominate.

“Their popularity,” he says, “is based on their long wear life and high efficiency.”

Ghana is a particular success story for UMD pumps, according to Hall, with nearly all gold mines there using the equipment manufacturer’s pumps to discharge slurry from their mills, he added.

“The KREBS UMD is popular at these mines largely because it lowers the total cost of ownership due to the millMax™ proprietary design that eliminates inefficient recirculation and grinding of slurry within the pump,” FLSmidth said.

“Prior to the millMAX wear ring design, slurry pumps experienced two major problems: mechanical grinding of solids between the suction liner and impeller, and flow recirculating back to the impeller eye on the suction side. Both of these problems decrease pump life and increase power consumption.”

The wear ring stops recirculation by closing the suction-side gap, while still allowing for a large clearance between the impeller and the suction liner, according to FLSmidth. This eliminates the grinding of solids. Adjusting the wear ring while the pump is running, meanwhile, restores performance and provides longer wear life and higher continuous efficiency, in all, lowering the total cost of ownership.

Hall says: “The UMD’s casing symmetry also means less inventory for customers. Mines that have pumps rotating in both left-hand and right-hand orientations must stock different casings, liners and impellers, adding to the operational costs.”

The advantage of the UMD is that it uses the same casing, suction liner, wear ring and back liner, which reduces overall net working capital.

The KREBS gravelMAX™ pumps continue to do well in the Mpumalanga coal sector of South Africa, according to FLSmith, where 14 of these pumps recently replaced competitor units on a single site.

Commonly applied in a cyclone feed application within the dense medium separation (DMS) circuit, the pump’s wider passage allows pumping of larger solids.

“We are also active in iron ore in South Africa with pumps in the DMS circuit,” Hall says. “A Lesotho diamond mine also operates KREBS pumps, which have demonstrated a four-fold increase in wear life compared to a competitor’s previous units.”

In sump pumps, FLSmidth has the vMAX™ range, which features a recessed impeller design allowing the pumps to run dry.

The company explains:“When the sump has been emptied of slurry, the recessed impeller allows the slurry to return safely down the discharge pipe without contacting the impeller, ensuring that it does not vibrate when dry.”

Another recent innovation in the KREBS slurryMAX range of pumps is being introduced to the Africa market after an enthusiastic response in the US and Australia, FLSmidth said. With multiple liner and impeller material options, the slurryMAX split-case pump can handle the majority of applications for any plant across multiple industries.

FLSmidth notes sustainability and digital mining developments in Q2 results

FLSmidth’s June quarter saw an improvement in revenue and profitability as the company’s Mining and Cement divisions continued to perform strongly.

The company’s order intake for the June quarter amounted to DKK5 billion ($752 million), down 2% from the same period a year ago. Mining order intake, specifically, declined 7%, mainly due to a lower capital order intake, the company said. This included an order of around DKK375 million from Rio Tinto for its Koodaideri iron ore project.

During the quarter, the company also completed the acquisition of IMP Automation.

FLSmidth’s order backlog stood at DKK16.8 billion by the end of June, up 16% from the same time last year.

Revenue increased 16% year-on-year in the quarter to DKK5.5 billion on high activity level, while earnings before interest taxes and amortisation came in at DKK487 million, up 28% year-on-year.

FLSmidth Group CEO, Thomas Schulz, said: “The second (June) quarter showed a strong performance with improved revenue and profitability, driven by both Mining and Cement. Following a slow start to the year, we have been successful at converting backlog to revenue in the second quarter. In close cooperation with our customers, we have continued to deliver on our vision to provide sustainable productivity enhancement.”

Schulz continued: “Our success with both service and capital orders, demonstrates our customers’ confidence in our ability to enhance their productivity. This is supported by an increased push for sustainable solutions that ties in well with our position, capabilities and track record.”

In the company’s Mining division, Schulz said the company saw increased interest for new technologies such as dry stack tailings, but also a general need to reduce water consumption in the production process. The company said the mining market remained robust.

The company added on the mining market: “Equipment demand continues to evolve around replacement and brownfield projects, with select greenfield opportunities. Miners are attentive of rising global issues and remain cautious on large and high-risk investments. The long-term pipeline for larger projects is encouraging, but most projects are currently not reaching further than the engineering/prefeasibility stage.”

It continued: “Customers across regions and commodities are increasingly demanding digitalised solutions to improve performance, reduce operating costs and maximise safety in operations. Similarly, customers show increased interest in technology to obtain a more sustainable production, not least our effective solutions for tailings management given the latest issues with tailings dams failures and the related environmental impact.”
