Kışladağ and Weir Minerals on the HPGR-backed gold recovery trail

Comminution of minerals, Environmental, Metallurgy, Mine operation news, Mineral processing, Mining consumables, Mining equipment, Mining services, Power supply for mines, Precious metals, Sustainable mining, , , , , , , , , , , , , ,

The story that led to the installation of a Weir Minerals Enduron® high pressure grinding roll (HPGR) at Eldorado Gold’s Kışladağ heap leach operation in Turkey is a fascinating read, as well as a great example of the benefits of using such technology.

Back in March 2018, Eldorado announced it would suspend mining to evaluate processing options for the operation. This decision followed extensive laboratory tests that indicated gold recoveries would continue to trend downwards around the base of the open pit where mining was underway.

This suspension, plus further engineering and test work, led to the company advancing the potential development of a mill project. The transition away from its heap leaching roots to a possible mill and carbon-in-leach (CIL) process would have added significant capital costs and shortened the mine life significantly.

Before making this significant capital decision, Eldorado paused to take time to undertake the necessary technical work and sought the technical collaboration of Weir Minerals on a solution.

“It was a very challenging period,” George Burns, President & CEO of Eldorado Gold Corporation, told IM. “Kışladağ is a cornerstone asset in our portfolio. It required collaboration with our geologists, metallurgists, site teams and technology providers, including Weir, working together on a solution.”

In late 2018, results showed increased recoveries from an extended leach cycle. Following a deeper understanding of the geometallurgical drivers of the sulphide component of the deposit, improved heap leach recoveries were realised by optimising the metallurgical conditions. With these improved recoveries confirmed, the heap leach plan was revised in early 2019. Eldorado announced plans to resume mining, crushing, stacking and heap leaching at Kışladağ, and suspended plans to build the processing plant.

The decision came following metallurgical test work on the material placed on the heap leach pad in 2018. Gold recovery had increasingly exceeded expectations throughout the year, providing a new, positive heap leaching outlook beyond the near term. At the same time, Eldorado worked with Weir Minerals on the potential use of an HPGR at the operation.

HPGR creates a finer particle size, which helps to liberate the gold particles, resulting in increased recoveries.

An improved understanding of the leaching process on its low-grade ore and the potential of this cost-effective grinding addition provided it with the confidence to continue heap leaching beyond the short-term time horizon previously envisaged.

“Our collaboration with Weir on this effort is an excellent example of how Eldorado collaborates with technology leaders and seeks out solutions,” Burns said. “We believe this is a strength of the company’s core business values. We are agile and flexible ‒ a good example in both business and operations to find innovative, technical solutions and demonstrate prudent capital discipline. Ultimately, the solution was the best technical and economic decision for Eldorado.”

Testing, testing, testing

“The relationship between Weir Minerals’ and Kışladağ goes back to 2013,” Bjorn Dierx, Global Product Manager Enduron HPGR, told IM.

The OEM had been provided with samples on several occasions to investigate different flowsheet possibilities.

“The benefits of HPGR in heap leaching recovery were known by the site’s crew,” he said.

Enduron technology was tested at the quaternary crushing stage before heap leaching, in the quaternary crushing stage before ball milling and at the tertiary crushing directly before heap leaching.

All the time, the mine operator, Tuprag, Eldorado Gold’s subsidiary in Turkey, was evaluating the impact on gold recovery.

Although HPGR in closed circuit with screening was also tested, most of the test campaigns were focused on a configuration with so-called ‘Partial Product Recycling’ (PPR), according to Serhat Onol, Weir Minerals Senior Process Engineer.

“This system includes splitter plates underneath the rolls which ‘cut’ a proportion of the product discharge and reverts this back to the HPGR head feed,” he explained. “This recycle stream can be adjusted online to adapt the product grind towards the downstream requirements.”

PPR is not an option for every application but for Tuprag – due to the feed and desired product size – all specifications showed it was the best route.

“The hybrid solution with screening serves to increase the flexibility and to control the circulating load to the HPGR,” Onol said.

With capacity rates of around 4,200 t/h at Kışladağ, the screening area requirement was reasonably high, he explained.

“The hybrid solution uses screening only for the recirculating stream: the centre product of the HPGR reports to downstream leaching, whereas the rest is recirculated,” he said. This not only removes the fines re-entering the HPGR and, thus, reduces the circulating load, but also avoids the over-grinding of fines before leaching.

The PPR option, itself, is a very flexible operation, with the adjustable discharge splitter plates providing the best circuit flexibility in terms of throughput and product size, according to Onol.

Great expectations

With the main driver of the HPGR installation being an improved gold recovery scenario, leading to an increased heap leach life, the pressure has been on Weir Minerals to come up with the goods.

The final flowsheet, which includes a 2.4 m diameter by 2.2 m long Enduron HPGR with the capacity to process 4,200 t/h, is much simpler than the existing circuit, according to Dierx, with less equipment to maintain, control and monitor.

“A single Enduron HPGR will replace all of the five existing tertiary crushers of which liners would have an average lifetime of circa-one month with a crusher availability of 85%,” he said. “The HPGR tyres have a wear life close to 18 months, with the HPGR achieving a high asset availability of more than 95%.

“Additionally, as a result of the HPGR combined with the hybrid PPR system, the existing four tertiary screens are also being decommissioned.”

Not only has the HPGR alleviated the use of this equipment, it is also set to boost that bottom line gold recovery.

“During testing, it was determined that the circuit configuration and HPGR operating conditions, such as pressure, have a direct influence on the gold recovery,” Dierx said. “The current expectation is that the average recovery increase after the commissioning of the Enduron solution will be approximately 4%.”

This could bring gold recovery to approximately 56%, as was declared in a 2020 press release from Eldorado that highlighted a 15-year mine life at Kışladağ with an average annual production of 160,000 oz.

In action

One of the largest brownfield HPGRs Weir Minerals has ever installed has just processed its first material at Kışladağ, which is testament to the hurdles both the Weir Minerals and Tuprag teams overcame during the height of the COVID-19 pandemic.

“Despite the challenges we faced during the pandemic, we were able to fully install the machine, including pre-commissioning, in only 22 weeks,” Dierx said.

This was achieved by minimising the amount of work carried out on site via pre-site testing and modular HPGR assembly.

“As the available footprint in existing sites is limited, the unique Enduron design (length:diameter ratio) not only improves the grinding efficiency but also allows for easier implementation with less civil requirements,” Dierx said.

The machine has the potential to be digitally connected to the Weir Synertrex® IoT platform where operators can benefit from direct access to maintenance specialists, who will be monitoring performance and provide necessary operating guidance.

And the Weir Minerals team is confident more Enduron HPGR installations will follow the one at Kışladağ.

“We are very proud of the product’s recognition by our customers as the Enduron HPGR has been selected for all major greenfield HPGR projects in the hard-rock space,” Dierx said. “Despite all the key Enduron differentiators, it is not only merely about the product but particularly the wider experience across Weir Minerals in both the upstream and downstream processes via our wide product portfolio.

“Particularly in these brownfield applications, the system is not operating in a vacuum and every process change influences how the overall circuit works. This requires tacit knowledge, which Weir Minerals holds across their global teams.”

Eldorado’s Burns concluded: “We are pleased to implement a solution that increases gold recovery and supports a 15-year mine life at Kışladağ, allowing Eldorado to continue to provide employment and economic opportunity in the region, as well as provide a solid foundation for future growth.

“Kışladağ has been the cornerstone asset of Eldorado for over a decade, producing over 3 Moz of gold and generating significant value for all stakeholders during that period. This project is a testament to our exceptional team and technology partners working together to execute in challenging circumstances during the pandemic.”

Weir Minerals expands the Cavex 2 hydrocyclone range with 650 model

Weir Minerals, building on over 20 years of Cavex® hydrocyclone experience, has added the Cavex 2 650 to its product line, with the cyclone set to deliver unparalleled results, the company says.

The release follows the recent launch of the Cavex 2 hydrocyclone, which brought with it the introduction of a LIG+™ inlet and chamber design that, the company says, produces a more stabilised flow pattern, further reduces turbulences and friction throughout the hydrocyclone and provides up to 30% additional capacity.

The latest 650 model has undergone years of research, lab testing and in-field testing to ensure it can withstand the rigours of heavy-duty industrial and abrasive applications. It also addresses the continual demand for increased operational and circuit capacity, and offers customers process improvements combined with digital technology, Weir Minerals said.

“It is important to note that enhancements of the hydrocyclone performance go hand in hand with improving the environmental footprint of the equipment,” the company said.

“By reducing bypass returning to the mill, fewer fines are returned back to the mill in a closed-circuit milling process, thus reducing the need for energy to be used to further process particles that are already small enough to move on to the next stage. This frees up mill capacity, previously used up with fine particles, for the size reduction of larger particles.”

As a hydrocyclone that can make a finer separation, the Cavex 2 650 can operate at a lower pressure for further energy savings or a higher feed density for water savings, while maintaining the existing cut size from the hydrocyclone, according to the company.

And, finally, using equipment with a higher volumetric capacity requires fewer units to be installed upfront as well as fewer consumable spare parts used over the life of the hydrocyclone.

Significant benefits to mining customers include:

  • Increased operational and circuit capacity up to 30%;
  • Maximised plant recovery by reducing the quantity of misclassified particles with an average improvement of the alpha parameter of more than 10%;
  • Improvements in bypass with an average of over 15%;
  • Opportunity to retrofit Cavex 2 650 cyclone into existing cyclone cluster footprints;
  • Less turbulence during the separation process due to the LIG+ inlet and elongated chamber design;
  • Enhanced performance with a Synertrex®-enabled monitoring system, which can detect roping or blockage conditions in advance for continuous, efficient operation of the hydrocyclone; and
  • Improvement of environmental footprint.

To satisfy all process conditions and slurry types, the Cavex 2 650 hydrocyclone comes with a range of material technology options including Linatex® premium rubber, R55 rubber, neoprene for high levels of hydrocarbon and ceramic.

The Cavex 2 650 hydrocyclone can be customised to suit almost any application with a variety of spigots, vortex finders and cone angles, according to the company.

These new hydrocyclones have already been put to the test, with the latest Cavex 2 650 hydrocyclone trial taking place with a customer in Chile. The testing was conducted in a large copper ore mine which had a SAG mill in a closed circuit with the cyclone cluster. The trial tested one Cavex 2 650 in a six-place cluster of existing Cavex cyclones and saw an improvement of up to 48.5% in circulating load and 31.7% in water bypass versus the original cluster, according to Weir Minerals.

A lab water test with the same hydrocyclone fittings as above also yielded positive results: a 211 mm inlet and 260 mm vortex finder delivered 16% more capacity at 100 kPa, and 17% more capacity at 250 kPa.

“These improvements in efficiency and bypass translate to increased savings for brownfield sites where the existing hydrocyclones do not have enough capacity and are maxed out, while greenfield projects benefit from savings in capital expense,” the company said.

The Cavex 2 650 hydrocyclone is the second in a range of standard sizes that Weir Minerals is planning to release, with more sizes in development to expand the current product range.

Weir Minerals wins large comminution order from Nigeria iron ore mine

Two of the largest screens built by Weir Minerals Africa are being designed and manufactured in South Africa as part of a process solution for an iron ore mine in Nigeria.

According to Tiisetso Masekwameng, General Manager Comminution at Weir Minerals Africa, the flowsheet accepted by the customer includes equipment for screening, washing, and grinding supplied by Weir Minerals.

“Within our scope of work are the two largest Enduron® double-deck banana screens built by Weir Minerals,” Masekwameng says. “This is made possible by the depth of design expertise in our Separation Technology Group, an eight-strong team conducting research and development.”

Steven Hunter, Separation Technology Group Leader at Weir Minerals Africa, says the two 51 t Enduron double-deck banana (DBHG 43/97) screens (one pictured) for this project were built upon the designs of the existing Weir Minerals screens range. These large machines measure 4.3 m wide and 9.7 m long and can process 1,750 t/h.

“The customer’s production requirements demanded this considerable size, so we optimised the design by minimising mass without compromising structural integrity,” Hunter says. “We conducted extensive finite element analysis on the whole machine but focused on the main structural elements, ensuring that the units were fit-for-purpose while still being light enough to be driven by the exciters.”

The size of the units still demanded the design and manufacture of Weir Minerals Africa’s largest exciter yet – the Enduron LTX 10. With 120 t of excitation force (at maximum setting), these units will drive the screens at a stroke of 9.4 mm and a gravitational force of 4.6 G.

Hunter said the screens are ready to be fitted with Weir’s IIoT platform, Synertrex. “This allows the machines to be monitored remotely; the system can measure the machine’s performance and any deviations arising that may require proactive attention,” he explained.

The order for Nigeria also includes two Trio® jaw crushers, two Trio cone crushers, two large 2 m by 8 m Trio apron feeders, two Trio pan feeders, eight Enduron vibrating screens and an Enduron HPGR.

For the clay washing circuit, Weir Minerals Africa will supply the mine with a Trio twin-shaft blade mill and Trio twin-shaft coarse washers as well as Warman® slurry pumps.

Weir Minerals strives for unmatched hydrocyclone performance with release of Cavex 2

IoT, Mineral processing, Mining equipment, Mining services, Sustainable mining, Water management, , , , , , , , , , , , ,

Almost 25 years after the original Cavex® hydrocyclone came into the classification market, Cavex 2 is set to introduce a step-change in performance and sustainability, with water and energy savings, according to Weir Minerals.

The launch of Cavex 2 marks a new generation of hydrocyclones, Weir says. Like the original Cavex hydrocyclones did more than two decades ago, Cavex 2 introduces new geometric features to offer performance unmatched by any cyclone in operation today, the company claims.

Debra Switzer, Global Product Manager for Hydrocyclones at Weir Minerals, said: “Our Cavex 1 design set an industry benchmark over two decades ago with its unique 360° laminar spiral inlet geometry, which significantly reduced turbulence. This design was so successful and desired by the market that it was widely replicated by competitors.

“Following years of research, development and trials, we have improved upon this design with the creation of LIG+™ inlet and chamber design. This unique design produces a more stabilised flow pattern, further reduces turbulences and friction throughout the hydrocyclone and provides up to 30% additional capacity.”

The advanced LIG+ design (patent pending) enables the Cavex 2 hydrocyclones to classify up to 30% more feed slurry, while occupying the same footprint as competitor hydrocyclones, according to Weir. This allows operators to achieve more throughput with fewer operating hydrocyclones, reducing the upfront capital expenditure.

The new design has taken into consideration the shape and angle of the hydrocyclone to ensure particles report to the correct stream, Weir says. This reduces recirculation and misclassification, further improving separation efficiency.

“Cavex 2 allows our customers to do more,” Switzer says. “A more sustainable circuit, with lower energy and water requirements. Expand the capacity of their existing circuits, without increasing the footprint of the cyclones or clusters. It’s the kind of generational engineering leap that will change the way circuits are designed for decades to come.”

Cavex 2 takes advantage of Weir Minerals’ Synertrex® IIoT technology, which enhances the overall performance of the hydrocyclone. Armed with this technology, operators are automatically alerted to roping or blockage conditions ahead of time, ensuring the hydrocyclone runs under the most optimal operating conditions.

“To minimise the amount of bypass that is produced in any hydrocyclone, it is favourable for it to operate in the semi-roping condition,” Switzer said. “This is often difficult to do continuously because any upset in the hydrocyclone’s feed conditions could move it into the roping condition, but, with Synertrex, this balancing act can be closely managed.”

Cavex 2 hydrocyclones can be customised to suit almost any application, according to Weir, with a variety of spigots, vortex finders and liners. Liners are available in a range of material options, including Weir Minerals’ proprietary R55® rubber compound or Linatex® premium rubber, both of which have been proven to outlast competitors elastomers in similar applications, Weir says. Liners can be replaced via a ‘snap-in’ system requiring zero adhesive, while smaller models (400CVD and below) are available with moulded fibreglass housings, the company says.

Switzer concluded: “Every stage of the Cavex 2’s design has been guided by the needs of our customers. As a consequence, it has been tested in multiple mining applications throughout the globe. These tests revealed outstanding results of up to 30% additional capacity.

“Decreasing ore grades and increasing need to reduce both water and energy usage have created the need for a low maintenance, highly efficient hydrocyclone, which can be readily retrofitted into existing circuits to increase throughput and maximise returns.

“I can’t wait for our customers to see what this new range is capable of.”

Weir Minerals has announced the launch of its Synertrex® platform, an advanced Industrial Internet of Things (IIoT) technology, which, it says, is set to transform the mining industry.

Delivering an advanced level of understanding, it allows operators to monitor every aspect of their equipment’s operation, prevent problems and increase throughput, according to Weir.

It uses network connectivity to capture equipment data and relay it to service centres, service technicians, their customers and Weir’s design centres for trend monitoring, proactive components supply and product improvement.

Ricardo Garib, Minerals Division President, said: “We believe our Synertrex platform will have a significant impact on the mining industry, transforming customer operations through improved productivity and safety.”

The company worked with technology market leaders Microsoft and Dell to develop “sophisticated predictive software and hardware” robust enough to operate in extreme conditions across the globe, he added.

IIoT is a network of equipment that connects to the internet and shares data that can be converted into unique insights. Demand for IIoT-enabled products is growing rapidly, particularly in the mining industry where it is being used in a number of areas including analytics, machine learning, and robotics.

“Synertrex is a cutting edge IIoT platform which harnesses the latest digital technology to transform productivity, foresee risk and enhance performance,” Weir said.

Using cloud computing, it involves placing smart sensors on an array of Weir Minerals’ products to gather critical operating data for advanced analysis. The data is transformed into powerful insights relayed to the customer through a digital interface.

“It can identify problems before they occur, reducing downtime, and optimise equipment performance across an entire circuit,” Weir said.

“Remote management allows for simplified maintenance. Wear and tear can be easily monitored, and trouble spots detected before they escalate into major issues. Whether it’s a drive system, structural or lubrication issues, Synertrex provides the tools to keep mining equipment at its most profitable.”

Through the platform, customers have detailed real-time insight into how equipment is performing, and machines will be able to learn over time, according to Weir.

Information is displayed on an easy to understand dashboard, which can be accessed via any device or integrated into existing operational systems. It will convey real-time, fact-based insights into machine performance and health, remaining useful life and other crucial indicators.

Fred Bradner, Vice President of Global Strategy, Sales and Marketing, said: “This platform will redefine field service standards and lead to greater performance, reliability and ultimately return on investment.”

At this stage, the platform can be paired with Warman® pumps, Cavex® hydrocyclones, GEHO® PD pumps, Enduron® HPGR, Enduron® screens and Enduron® crushers; however Weir has plans to expand the range of compatible products.

Customers with existing Weir products who wish to enable Synertrex will be able to retrofit sensors to equipment.

John McNulty, Vice President of Global Engineering and Technology, said: “This technology is backed by our 147 years of experience and unrivalled service support. Our team travel to the customers’ site to install the sensors, connect to the cloud and provide training to ensure they fully understand how the Synertrex platform works and what it can do.

“The data gathered from Synertrex combined with our in-depth product knowledge, provides unique insights on performance that only the OEM can deliver. Our extensive service network can quickly act on the outputs from Synertrex to provide unrivalled on-site support to our customers.”

Weir sees strong demand for brownfield mine solutions in H1 results

Weir Minerals clocked a solid performance in the first half of 2018 and was ably supported by strong demand for new equipment and aftermarket services from its Minerals division.

The company’s orders from continuing operations (minus its Flow Control division) were up 20% year-on-year in the six month period at £1.17 billion, while operating profit jumped 38% to £160 million.

Minerals orders increased 12% to £728 million, with original equipment orders up 9% (£222 million) and aftermarket orders up 14% (£728 million). Operating profit within the division rose 13% to £112 million.

While its Minerals division performed well, its Oil & Gas division topped it with a 35% year-on-year order jump to £438 million as North American upstream oil and gas markets grew strongly.

Weir said: “Activity in mining markets continued to grow strongly as customers ramped up production to maximise the benefits of supportive commodity prices. Demand was particularly good for brownfield solutions that help debottleneck, increase throughput and reduce downtime of existing mines.”

The pipeline of new projects continued to increase driven by good long-term fundamentals for commodities such as copper, gold and lithium, the company said.

“Customers remained disciplined about committing to new greenfield developments, although a small number of projects received final approval.”

Weir said its early investment in deploying more engineers to customer sites to help miners improve productivity had continued to support strong order growth in the first six months of the year with sales from integrated solutions, which leverage the division’s portfolio of premium products, delivering around £50 million in additional orders. Weir noted engineers completed 374 site audits in the period.

“The division also continued to grow market share through its successful trials programme that sees it go head to head with competitor products to demonstrate the superior performance of Weir equipment,” the company said.

The first half also saw the opening of additional service centres in Zambia, Chile and Peru to further extend Weir’s service network.

Weir’s technology programmes focused on continuous improvement in the division’s core products while also developing its Synertrex® IoT solution. Weir said full commercialisation of this technology in mining markets was planned for the second half of the year.

Synertrex uses network connectivity to capture equipment data and relay it to service centres, service technicians, their customers and Weir’s design centres for trend monitoring, proactive components supply and product improvement.

After the end of the quarter, Weir completed the acquisition of Esco Corp in a deal that came with an enterprise value of $1.29 billion.
