Zinnwald Lithium and Metso engaged in ‘one-stop shop’ studies for LiOH project

Zinnwald Lithium plc and Metso have continued to make progress developing the beneficiation plant concept for the integrated Zinnwald lithium project near Dresden, Germany.

This project, which is situated in the heart of the European chemical and automotive industries, is designed to supply battery-grade lithium hydroxide (LiOH) to the battery sector.

Anton du Plessis, CEO of Zinnwald Lithium, said: “Achieving resilience and sustainability for the electric vehicle battery supply chain is essential, including in Europe where over 30 new gigafactories are planned by 2030.

“Our vision is to build a world-leading integrated lithium hydroxide operation to support this supply chain, adhering to the highest environmental standards. We are therefore delighted with the progress being made with Metso as we look to design the best possible particle sorting, otherwise known as the beneficiation process, for the plant.”

Metso was engaged to assist Zinnwald Lithium with its definitive feasibility study in early 2022. The two companies have since been working on developing a successful beneficiation process flowsheet based on a complete mineralogical study, batch and locked cycle tests. The design basis of the tests considers the mixture of two distinctive lithium ore types, Alibite Granite and Quartz Mica Greisen, potentially expanding the resource base considerably.

du Plessis said: “After the completion of the beneficiation pilot, we will start refinement of the calcination and hydrometallurgical flowsheet. We have partnered with Metso to develop and deliver this project as a ‘one-stop shop’ to reduce the need for engagement with multiple suppliers and to maximise in-house expertise in the design of the plant from run-of-mine to the battery-grade final product.”

Mikko Rantaharju, Vice President, Hydrometallurgy at Metso, added: “Metso is delighted to support Zinnwald Lithium with the development of this ambitious project. Development and supply of state-of-the-art, sustainable processes and equipment for the critical minerals required for the electric vehicle supply chain is an essential part of our minerals processing expertise.”

Metso provides sustainable technology and equipment for all ore types, including the critical minerals required for the energy transition, supported by its unique Planet Positive offering.

Metso says its solutions for battery minerals cover the entire lithium, nickel and cobalt production chain – from the mine to battery materials and black mass recycling – with project scopes ranging from equipment packages to plant deliveries. For high-end lithium-ion battery chemicals production, Metso’s expertise covers the extraction of lithium from various lithium sources up to battery-grade lithium salts.

Monadelphous rewarded with A$200M contract at Albemarle’s Kemerton lithium hydroxide plant

Engineering company Monadelphous Group has secured a major construction contract with Albemarle valued at approximately A$200 million ($135 million) associated with the expansion of the Kemerton lithium hydroxide plant in the south west region of Western Australia.

The contract includes front-end pyromet structural, mechanical, piping, electrical and instrumentation works associated with two new lithium processing trains (trains 3 and 4).

The award follows the successful delivery of construction packages on trains 1 and 2, and the recently awarded long-term maintenance and sustaining capital projects contracts at Albemarle’s Kemerton operations.

Work will commence onsite later this year and is expected to be completed in the second half of 2025.

Monadelphous Managing Director, Zoran Bebic, said this award, in addition to the award announced last week with Fortescue Metals Group for work at the Christmas Creek mine site, represent the first in a new wave of major construction projects to come to market.

The company’s work at Christmas Creek involves the supply and construction of an overland conveyor and transfer station, with the scope including civil, structural, mechanical, piping, electrical and instrumentation works.

“We are extremely pleased to have secured these key construction opportunities, and look forward to continuing to deliver high quality solutions for customers, as well as supporting local communities through the provision of employment and supply opportunities,” he said.

Albemarle says expansion of Kemerton represents the biggest investment by any company in downstream processing of lithium in Australia.

The Kemerton plant initially consisted of three production trains, each producing 20,000 t/y of lithium hydroxide, with a potential expansion to five trains that will see production increase to 100,000 t/y by around 2025. The plant will be supplied with lithium concentrate produced at the nearby Greenbushes mine.

Avalon Advanced Materials and Metso sign MoU on lithium hydroxide production plan

Avalon Advanced Materials Inc has signed a memorandum of understanding to create a strategic partnership with Metso aimed at establishing terms to develop a lithium hydroxide production facility to process lithium mineral concentrates that are essential for the North American electric vehicle (EV) battery value chain.

Avalon intends to deploy Metso’s technology to construct and operationalise a full-service lithium processing facility at the company’s recently acquired Thunder Bay, Ontario industrial site.

Upon completion of the project, Avalon says it will be the first vertically integrated lithium producer in Ontario, while ensuring Canada’s EV battery manufacturing base has a stable, proximate and long-term supply of this resource.

“Metso’s platform and technological solutions perfectly complement Avalon’s vision to complete an integrated lithium value chain in Ontario, predicated on innovative process solutions,” Zeeshan Syed, President of Avalon, said. “We view Metso as an integral part of this rapidly growing sector, and a foundational partner in developing internationally best-in-class processing capabilities that are environmentally sustainable, allowing Avalon to meet the soaring demand for battery-grade lithium.”

The non-binding MoU stipulates:
• The pursuit of a definitive agreement to establish a lithium hydroxide processing facility in Thunder Bay;
• Avalon to license Metso technology and solutions to produce lithium hydroxide cathode materials to serve the EV market;
• Allow Metso to conduct testing and engineering work across Avalon’s portfolio of critical-mineral projects, including the company’s flagship deposit at Separation Rapids near Kenora, Ontario; and
• The parties anticipate reaching a definitive agreement on or before September 1, 2023.

Metso’s sustainable next-generation production and processing technologies are being deployed internationally by governments and clean-energy producers in order to address and deliver the necessary supply required by the emerging EV battery industry, Avalon says.

Avalon’s strategic partnership with Metso is a first in Canada, and is a significant step towards helping the company execute on its vertically-integrated business strategy – and, in turn, entrench Ontario’s position as an advanced manufacturing hub serving not only North America, but the world.

Mikko Rantaharju, Head of Hydrometallurgy at Metso, said: “Metso is looking forward to partnering with Avalon and be part of its long-term vision to be a mid-stream supplier in the lithium hydroxide space. We are aligned with Avalon’s vision of the future and proud to play a key role in technology supply and advancement into clean energy solutions.

”We are also extremely excited to be partnering with the first Ontario conversion facility with Metso’s technology. The innovation advantages of the alkaline process allow for elimination of the use of potentially harmful chemicals such as sulfuric acid and comparatively reduces overall solid waste and emissions, making it environmentally friendlier and overall, safer for workers and local surrounding communities.”

Avalon is a Canadian mineral development company focused on vertically integrating the Ontario lithium value chain. The company is currently developing its Separation Rapids lithium deposit near Kenora, while continuing to advance other projects in its portfolio, including its 100%-owned Lilypad spodumene-cesium-tantalum project near Fort Hope, Ontario.

In additional to extraction activities, Avalon is executing on its key strategic objective of developing Ontario’s first midstream lithium hydroxide processing facility, a vital link bridging the gap between upstream lithium production and downstream EV battery manufacturing.

For battery minerals, Metso provides sustainable technology and equipment for the entire production chain, from the mine to battery materials and black mass recycling with project scopes ranging from equipment packages to plant deliveries.

Metso extends calcining and acid roasting input at Kemerton lithium hydroxide processing plant

Metso says it has been awarded a contract to deliver ancillary equipment for Albemarle Lithium Pty Ltd’s calcining and acid roasting facilities at the Kemerton lithium hydroxide processing plant in Western Australia.

This agreeement is an addendum to the two pyro processing and comminution lines that were awarded to Metso and announced in December 2022. The value of the contract is approximately €40 million ($43.5 million).

Metso’s scope of delivery includes selected material handling and gas cleaning equipment for the calciner, calcine grinding and acid vapour sections.

Chris Urban, Vice President, Heat Transfer at Metso, said: “We are pleased that Albemarle, which is one of the largest lithium producers in the world, has selected us as the partner for their lithium hydroxide processing plants. In addition to the pyro processing and comminution lines ordered, it was also our honour to deliver two pyro lines, which were recently commissioned.”

The Kemerton plant initially consisted of three production trains, each producing 20,000 t/y of lithium hydroxide, with a potential expansion to five trains that will see production increase to 100,000 t/y by around 2025. The plant will be supplied with lithium concentrate produced at the nearby Greenbushes mine.

Rockwell Automation to provide process control solution at Cornish Lithium demo plant

Rockwell Automation says it is working with Cornish Lithium on a demonstration plant to validate the sustainable production of lithium hydroxide from micaceous granite.

The Cornish Lithium demonstration plant will be controlled by the PlantPAx® modern distributed control system from Rockwell Automation. This DCS provides a single, plant-wide control system and increased flexibility for better business decisions, according to the company.

Phil Hadfield, UK Managing Director, Rockwell Automation, said: “Rockwell Automation has both the technology and domain expertise to support the complex lithium extraction process. We have successfully worked in lithium projects around the world, including Australia, Africa and South America. The integrated architecture from Rockwell Automation provides end-to-end system integration. The systems are designed with scalability in mind, leveraging the new advancements in digital technology.”

Cornish Lithium has licensed an acid-leaching, selective precipitation and crystallisation process developed to create lithium hydroxide from micaceous granite. This process is expected to be more environmentally friendly than the traditional hard-rock process, which usually involves a significant calcination step, where the ore is calcined at 1,000°C, the company says.

The validity of the process has already been tested at a small pilot plant in Australia and proven that it can produce lithium hydroxide monohydrate salt, according to Cornish Lithium. The next step is constructing a demonstration plant at the site in Cornwall. This will be a complete conceptual end-to-end process from the raw material to lithium hydroxide, using all the same equipment employed in a full-scale facility with just one or two changes for scale reasons. This simulation of the actual process will assure all stakeholders and potential customers of the effectiveness of the processing technology on Cornish ore ahead of the construction of a full-scale production facility.

David Moseley, Process Manager, Hard Rock Minerals, Cornish Lithium, said: “Rockwell Automation will play quite a crucial role in what we are doing. We want to try and simulate as much as possible the industrial process control that we might employ at full scale. We are trying to put as much of that into the demonstration plant as possible because it is a complex multi-stage process with lots of recycles – and sequential operation, particularly with filtration, and process control is critical. Rockwell Automation is putting together the process control philosophy based on our instrumentation. This is a series of different process control units that must be coordinated to have a plant that will operate effectively.”

Two plants will be built; one is a mineral concentration plant where raw ore is crushed, milled and separated to create lithium-enriched mica concentrate. The second is the chemical plant, with a hydrometallurgical acid leaching system that produces lithium sulphate, which is converted into lithium hydroxide. The chemical plant combines chemical reactors, precipitators, filtration and crystallisation. The demonstration plant is currently under construction and, when commissioned, is expected to operate for a year.

Keliber to use Metso Outotec’s Planet Positive leaching technology at lithium refinery

Sibanye-Stillwater’s subsidiary Keliber has partnered with Metso Outotec to provide its sustainable soda pressure leaching technology for Keliber’s lithium hydroxide refinery, which will be built in Kokkola, Finland.

Keliber owns the advanced lithium project located in the Kaustinen region of Finland, which intends to be one of the first integrated operations in Europe to sustainably produce battery-grade lithium hydroxide using its own ore. In addition, Metso Outotec will provide key processes for Keliber’s concentrator plant, which will be located on the border of Kaustinen and Kronoby municipalities in Finland.

Following the approval for the Keliber lithium project by Sibanye-Stillwater’s board, as announced on November 28, 2022, the first and biggest technology contract has now been signed. The combined order value is approximately €120 million ($128 million), of which approximately €80 million is committed for the Kokkola lithium hydroxide refinery. The planned production of the lithium hydroxide refinery is 15,000 t/y of lithium hydroxide monohydrate.

Metso Outotec’s scope of delivery consists of the engineering and supply of most of the equipment for the lithium hydroxide refinery, as well as installation and commissioning services and training. For the concentrator plant, Metso Outotec’s scope of delivery includes engineering and supply of all the main equipment.

Hannu Hautala, CEO of Keliber, said: “Metso Outotec’s Planet Positive portfolio, which focuses on the most environmentally-efficient technologies, supports the potential for the Keliber project to be a world-class lithium hydroxide producer, that is among the most sustainable in the world.”

Metso Outotec has developed lithium hard-rock-related technologies for some 20 years, and collaboration with Keliber started already in the early 2000s.

Heikki Pekkarinen, Chief Project Officer, said: “The lithium hydroxide production process has been successfully tested with Keliber’s concentrate in Metso Outotec’s pilot plant during the last few years. Metso Outotec has also provided the basic engineering for the refinery, which has given us a well-based detailed technical and economic performance review of the plant. During the planning and piloting stages, new initiatives were also developed to improve the environmental and production performance of both plants.”

Markku Teräsvasara, President of the Minerals business area at Metso Outotec, said: “We are excited that Metso Outotec has been selected as a partner for Keliber’s world-class concentrator plant and refinery project. Our proprietary soda pressure leaching technology will enable exceptional material and energy efficiency for the lithium hydroxide refinery, contributing to the sustainability and profitability of the whole project.”

Zinnwald striving for battery-electric circularity with lithium project development

The development of the integrated Zinnwald lithium project in Germany could see the incorporation of a battery-electric fleet of LHDs and the return of metal production to a region of saxony with mining history dating back to the Middle Ages.

The London-listed owner of the project, Zinnwald Lithium Plc, has just released a preliminary economic study on its namesake project focused on supplying battery-grade lithium hydroxide to the European battery sector.

As with any responsible battery metal project being developed today, the project’s ‘green credentials’ are being considered even at this early stage.

Zinnwald Lithium has been keen to flag these, mentioning the project is located close to the German chemical industry, a fact that should enable it to draw on a well trained and experienced workforce with well-developed infrastructure, plus reduce the ‘carbon footprint’ of the final end-use product.

This focus will see all aspects of the project – from mining through to production of the end product – located near to the deposit itself.

Zinnwald Lithium also said the project has the potential to be a low- or ‘zero-waste’ project, as the vast majority of both its mined product and co-products have their own large-scale end-markets.

This could see it produce not only battery-grade lithium hydroxide monohydrate products, but sulphate of potash (SOP) for the fertiliser market and precipitated calcium carbonate (PCC) – the latter being a key filling material in the paper manufacturing process.

The project now includes an underground mine with a nominal output of approximately 880,000 t/y of ore at an estimated 3,004 ppm Li and 75,000 t/y of barren rock. Processing, including mechanical separation, lithium activation and lithium fabrication, will be carried out at an industrial facility near the village of Bärenstein, near the existing underground mine access and an existing site for tailings deposition with significant remaining capacity.

With a 7-km partly-existing network of underground drives and adits from the ‘Zinnerz Altenberg’ tin mine, which closed in 1991, already mapped out, the bulk of ore haulage is expected to be via either conveyor or rail

The nominal output capacity of the project is targeted at circa-12,000 t/y LiOH with circa-56,900 t/y of SOP, 16,000 t/y of PCC, circa-75,000 t/y of granite and 100,000 t/y of sand as by-products.

The company is looking to complete the ‘circularity’ dynamic in its fleet and equipment selection, according to CEO, Anton Du Plessis, who mentioned that electric LHDs could be used to load and haul ore to an ore pass in the envisaged operation.

He said the cost estimates to use such equipment – which are factored into the project’s $336.5 million initial construction capital expenditure bill – have come from Epiroc, which has a variety of battery-operated mobile equipment.

“The base case is battery-operated loaders,” he told IM. “The final selection will be based on an optimisation study where, in particular, partly trolley-fed haulage systems will be investigated.”

Forms of automation are also being studied, Du Plessis said, with the caveat that “only select technologies we consider proven” will be evaluated.

Zinnwald Lithium is also looking at electric options for long-hole drilling underground, with both battery-based units and cabled versions under consideration and requiring firming up in the optimisation study.

With a 7-km partly-existing network of underground drives and adits from the ‘Zinnerz Altenberg’ tin mine, which closed in 1991, already mapped out, the bulk of ore haulage is expected to be via either conveyor or rail. The former, of course, will be powered by electricity, but the company is also considering potential battery-electric options for the latter, according to Du Plessis.

The company is blessed with existing infrastructure at the mine, which should help it in advancing the project at the pace its potential end-use manufacturing suppliers would like. It is already evaluating options for the construction stage – with an engineering, procurement and construction management contract the most likely option – and it has plans to conclude a feasibility study by the end of next year.

Du Plessis said while most of the fixed assets have been removed or were deemed outdated a long time ago from the former operating underground mine, other infrastructure was in good shape.

“The excavations, main level, underground workshop, ventilation shafts and, particularly, 2020 refurbished access tunnel provide a very good starting point for our project,” he said. “The access tunnel was originally constructed for dewatering the old mine and, therefore, the mine and the tunnel have been maintained very well.”

The company is now shifting to the bankable feasibility study and currently selecting partners for the project.

With what it calls a “simple, five-stage processing” route confirmed by test work for the extracted material at Zinnwald, the company is looking to select OEMs with the optimal concept for the project, Du Plessis said.

“In the PEA, mineral processing equipment cost is based on Metso Outotec estimates, pyrometallurgy is based on Cemtec technology, and hydrometallurgy is based on various providers’ technology,” he clarified.

Tianqi and IGO herald battery-grade lithium milestone at Kwinana refinery

Tianqi Lithium Energy Australia Pty Ltd (TLEA) has announced first production of battery-grade lithium from its plant in Kwinana, Western Australia, marking the first time battery-grade lithium, or lithium hydroxide monohydrate (LHM), has been produced in Australia in commercial quantities.

This is a significant milestone for TLEA and Australian mining as the sector expands to meet rapidly growing demand for rechargeable batteries, primarily from the electric vehicle and energy storage system industries, TLEA, a joint venture between IGO (49%) and Tianqi Lithium (51%), says.

TLEA’s Kwinana plant has successfully met internal certification processes with the on-site laboratory confirming that battery-grade specification has been met on 10 t of lithium hydroxide, produced consistently over several days. Samples have been sent for independent verification, TLEA says.

The next step in the plant’s ramp-up process is customer qualification, which will be completed over the next four to eight months. During this time, the plant will continue to focus on stable, consistent and reliable production of battery-grade lithium.

“We are immensely proud to demonstrate that Australia can value add to its minerals onshore as it enhances its reputation as a critical contributor to the production of batteries for electric vehicles and energy storage, which are absolutely vital for the decarbonisation of the world’s economy,” TLK Chief Operating Officer, Raj Surendran, said.

“This is an exciting time for our shareholders, suppliers and service providers who have contributed to the construction and ramp-up of the Kwinana Plant, and our employees who have worked so hard to turn the dream of producing battery-grade lithium hydroxide in Australia into a reality.

“Today’s milestone proves Australia has the capability and expertise to transition from a ‘dig it and ship it’ minerals supplier to a downstream supplier of value-added product.

“However, we also remain acutely aware that there is more work to do to establish the Kwinana plant as a reliable, significant producer of battery-grade lithium, starting with customer acceptance.”

TLEA owns the first lithium hydroxide plant in Australia and the largest in the world to be built and operated outside of China. Lithium hydroxide produced at the plant will be containerised and exported from the Port of Fremantle to customers around the globe.

Surendran said the first train at TLEA’s Kwinana Plant will now continue its ramp-up towards its nameplate capacity of 24,000 t/y of battery grade lithium hydroxide.

Lithium hydroxide is a lithium-based compound derived from spodumene, a lithium-bearing pegmatite mineral. Spodumene is sourced directly from the Greenbushes mine 250 km southwest of Kwinana (Albemarle 50%, Tianqi Corporation 25%, IGO Ltd 25%).

KIZAD and Lepidico to collaborate on Middle East’s first lithium production facility

Khalifa Industrial Zone Abu Dhabi (KIZAD), a subsidiary of AD Ports Group’s Industrial Cities & Free Zone (IC&FZ) cluster, has announced the signing of an agreement with Lepidico Ltd, a lithium exploration and development company, for establishing the first lithium production facility in the Middle East, utilising a first-of-its-kind process.

Covering a land area of 57,000 sq.m, the first phase of Lepidico’s development for the AED348 million ($95 million) chemical plant will house clean-tech L-Max® and LOH-Max® process technologies. The process extracts lithium and recovers valuable by-products from lithium mica and phosphate minerals. As an eco-friendly, zero-waste facility, the residue, predominantly gypsum, will be repurposed for use in the construction industry, KIZAD said.

Abdullah Al Hameli, Head of Industrial Cities & Free Zone Cluster, AD Ports Group, said: “AD Ports Group is committed to supporting cutting-edge innovative solutions that advance industrial development within the UAE. Lepidico’s process technology also aligns with our sustainability principles and our vision to support innovative environmental solutions that contribute to the long-term sustainable development of Abu Dhabi, as outlined by the leadership of the emirate.

“We are pleased to host an innovative and environmentally-conscious company like Lepidico, which aims to establish the region’s first lithium production facility in the Middle East, located in KIZAD. The project is a critical enabler for developing an electric vehicle supply chain in the Middle East.”

Joe Walsh, Managing Director, Lepidico, said: “The signing of the agreement represents an important milestone in developing the first phase of the new chemical plant and enables critical path geotechnical and infrastructure EPCM works to commence.

“In our endeavour to developing a sustainable lithium industry, we plan to integrate social, economic, environmental, and health and safety opportunities as part of the project design criteria and strive for a zero-waste process through our innovative and proprietary technologies. We look forward to working with AD Ports Group as we bring the lithium chemical industry to the UAE and wider Middle East region.”

The vertically integrated Phase 1 Project (P1P) comprises two small scale open-pit mines that will feed a mineral concentrator in Namibia, following which the lepidolite concentrate will be shipped to the facility being developed in KIZAD via Khalifa Port.

Lepidico plans to invest approximately $95 million for the chemical conversion plant in Abu Dhabi for an initial term of 25 years, which will employ the company’s proprietary process technologies, L-Max and LOH-Max. The project is a significant step forward in developing a sustainable lithium hydroxide industry and supports the global clean energy revolution, the companies said.

HALMEK LITHIUM to work with Metso Outotec on lithium hydroxide plant

HALMEK LITHIUM has selected Metso Outotec’s patented lithium hydroxide process for production of battery-grade lithium hydroxide at its greenfield plant in the Tula region in Russia.

The order value, which is not disclosed, has been booked in the company’s Metals June quarter orders received.

Metso Outotec’s scope of delivery consists of the engineering and key equipment supply for the lithium hydroxide process, the basis of which will be the Metso Outotec OKTOP® autoclave plant. The environmentally sound production process is one of Metso Outotec’s more than 100 Planet Positive products, the company said.

Pavel Galchenko, VP, Halmek Lithium, said: “One of the most important tasks in the project was the selection of technology. Instead of the more traditional sulphuric acid processing to produce lithium hydroxide, we decided to choose the Metso Outotec lithium hydroxide process as it is the most promising and environmentally-sound process at the moment.

“The pilot tests conducted at the Metso Outotec Research Center in Pori, Finland, provided excellent results.”

Mikko Rantaharju, Vice President, Hydrometallurgy business line at Metso Outotec, said: “Metso Outotec has developed lithium hard rock-related technologies for some 20 years now. It started with the battery-grade lithium carbonate process and, when the market changed to favour lithium hydroxide, the process flowsheet was converted to directly produce battery-grade lithium hydroxide monohydrate from spodumene.

“Both of the processes are patented and will be significant assets in our battery chemicals business, meeting the need to produce high-end lithium-ion battery chemistries for the growing market.”

HALMEK LITHIUM’s new hydrometallurgical plant, which will complement its existing lithium hydroxide plant, is currently under construction. As raw material, the new plant will use spodumene concentrate; it will feature a capacity of 20,000 t/y of battery-grade lithium hydroxide monohydrate, which is used in the production of batteries for electric vehicles. The first production line is planned to start up in 2023, and the second production line with a capacity of 20,000 t/y is expected to start production in 2026.
