Albemarle Lithium Pty Ltd has awarded Metso Outotec an order for two pyro processing and comminution lines for its Kemerton lithium hydroxide processing plant in Western Australia, the OEM says.

Previously, Metso Outotec delivered two similar pyro process lines to the plant as part of another order.

Metso Outotec’s delivery consists of rotary calciner kilns and coolers, Premier™ ball mills, acid roast indirect rotary kilns and coolers for the pyro processing lines, as well as advisory services for installation and commissioning. Over 90% of the approximately €55 million ($58.6 million) order value is booked in Metso Outotec’s Metals fourth-quarter (December-quarter) orders received and the rest in its Minerals’ orders received.

Chris Urban, Vice President, Heat Transfer at Metso Outotec, said: “Albemarle is one of the largest lithium producers in the world. Commissioning and ramp up of the first two pyro lines delivered by us is currently taking place at the Kemerton plant in Western Australia, and we are delighted to now have received orders for two additional Metso Outotec pyro processing lines.”

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.

Zenith Energy has converted the Letter of Award it signed with Liontown Resources to supply electricity to the Kathleen Valley lithium project in Western Australia into a Power Purchase Agreement.

The PPA will see Zenith supply the project with electricity for a period of 15 years as part of a 95 MW hybrid power station setup at the mine.

Zenith has, since the signing of the Letter of Award, announced in September, progressed the planning, engineering and design works for the hybrid power station, including the order of long-lead items such as the wind turbines.

With 46 MW of emission-free power generation capacity, the 95 MW hybrid power station is currently expected to be one of the largest off-grid wind-solar-battery storage renewable energy facilities in the mining industry in Australia.

The thermal components are designed to operate in “engine off” mode at various times, enabling Liontown to operate from 100% renewable energy during periods of high wind and solar resource, the companies say.

The hybrid power station is expected to start up around the same time as the Kathleen Valley process plant is commissioned, currently slated for the first half of 2024.

The plant will include wind generation from five wind turbines each capable of generating 6 MW. A 16 MWp fixed axis solar photovoltaic array coupled to a 17 MW/19 MWh battery energy storage system will provide additional clean energy, supported by synchronous condensers that provide critical system stability and resilience, Zenith said. The thermal power component will comprise 27 MW of gas generation and 5 MW of diesel standby generation.

Kathleen Valley is one of the world’s largest and highest-grade hard-rock lithium deposits and, with an initial 2.5 Mt/y production capacity, is expected to supply circa-500,000 t/y of 6% lithium oxide concentrate, according to the company. With first production expected in June quarter of 2024, the deposit will also produce tantalum pentoxide.

Ioneer Ltd has signed a non-binding memorandum of understanding (MoU) with Shell Canada Energy for the sale of sulphur to Ioneer for its Rhyolite Ridge lithium-boron project in Nevada, USA.

Securing the supply of key reagents for ore processing is an important step along the critical pathway to developing the Rhyolite Ridge project, Ioneer says.

Under the MoU, Ioneer will purchase up to 500,000 t of high-quality sulphur annually from Shell, which would fulfil the estimated annual sulphur requirement for the project. The agreement follows a Letter of Intent signed by the two companies in December 2019. With a binding commitment to negotiate exclusively with one another, it is the intention of both parties to advance the MoU into a Definitive Agreement at the appropriate time, Ioneer says.

Once operational, Rhyolite Ridge is expected to produce 20,600 t/y of lithium carbonate, converting in year four to 22,000 t/y of battery-grade lithium hydroxide, and 174,400 t/y of boric acid.

Ioneer’s Managing Director, Bernard Rowe, said: “With this MoU, Ioneer takes another key step to secure sulphur for the Rhyolite Ridge lithium-boron project. Sulphur is a primary input for our process as it will be converted into the sulphuric acid required for leaching the ore as well as releasing heat which is recovered to produce carbon free power and steam for the facility. Shell is an ideal partner for this effort, and we look forward to furthering our partnership together on additional decarbonisation solutions while providing materials for a sustainable future.”

Peter Zissos, GM Global Sulphur & Thiogro from Shell, said: “We are excited to expand our partnership with Ioneer to include the sale of sulphur while collaborating on various decarbonisation solutions. Sulphur’s second largest use is for mining, including for the extraction of electric vehicle metals like lithium. With safe and reliable delivery of sulphur to customers like Ioneer, Shell Sulphur Solutions is delivering inputs critical for renewable energy production and management.”

Pilbara Minerals and Calix commit to lithium calcination tech demo plant at Pilgangoora

Pilbara Minerals and Calix have executed a joint venture (JV) agreement for the development of a demonstration plant using Calix’s patented calcination technology at the Pilgangoora project in Western Australia.

The aim of the joint venture is to produce lithium salts via an innovative midstream “value added” refining process leveraging this calcination technology. It will also explore the potential commercialisation of the process.

The objective of the “Mid-Stream Demonstration Plant Project” is to deliver a superior value-added lithium product enabling lower product cost, reduced carbon energy intensity, and reduction of waste product logistics.

The unincorporated JV will be a 55:45 agreement in favour of Pilbara Minerals, with each party funding their share of operating and capital costs and Calix licensing its patented technology and calcination knowhow into the JV. Pilbara Minerals will manage the demo plant at Pilgangoora, overseeing both the construction and operational phases.

A successful demonstration of the calcination technology via this plant may then lead to its commercialisation with the JV licensing the technology to the global spodumene processing industry, Pilbara Minerals says.

It follows a previous agreement signed back in June.

The project aims to demonstrate a superior value-added lithium product to the existing industry supply chain, while also potentially delivering a significant reduction in carbon intensity, with potential industry benefits including:

  • Product cost – the flash calcination technology developed by Calix has the potential to treat very fine spodumene concentrate at lower lithia grades and materially improve overall lithia recovery, thereby enabling a lower cost per lithia unit;
  • Carbon intensity reduction – substantial carbon emission reduction through the electrification of the Mid-Stream process, including spodumene calcining, enabling the potential to use up to 100% renewable sourced power; and
  • Waste reduction/handing – rationalisation of the carbon footprint via reduced waste movement across transport and logistics supply chains from a more lithium-dense, and near zero-waste final product.

Pilbara Minerals’ Managing Director and CEO, Dale Henderson, said: “The Mid-Stream project has the potential to be a game changer for our industry. If successful, we will be able to deliver a superior chemical intermediary product to market compared to spodumene concentrate.

“This intermediate product offers a higher concentration in lithium and less impurities whilst being produced through a new process that reduces CO2 emissions compared to the traditional process route for hard-rock spodumene chemical conversion.”

Macmahon Holdings says it has received a Notice of Award from Talison Lithium Australia for the load and haul mining works at its Greenbushes lithium project in the southwest of Western Australia.

Talison Lithium is a Western Australia-based mining company which is 51%-owned by a joint venture comprising Tianqi Lithium Corporation and IGO Limited, and 49%-owned by Albemarle Corporation.

Together with its predecessor company, Talison Lithium has been producing lithium concentrates at Greenbushes since 1983 which are ultimately used in lithium batteries. The Greenbushes project, directly south and adjacent to the town of Greenbushes in Western Australia, is a major supplier of lithium mineral concentrates.

The scope of works on the Greenbushes project includes open-pit mining activities of load and haul, and crusher feed.

Subject to final documentation of certain in-principle agreed terms and signing within 30 days, the contract will commence on July 1, 2023, for a seven-year period and has an option to extend for up to two years. The contract is estimated to generate revenue in excess of A$1.1 billion ($731 million) over its initial seven-year term.

Key mining equipment required for commencement will be from deployment of Macmahon’s existing available mining fleet with minimal impact to capital expenditure in the 2023 financial year, Macmahon says. The maximum remaining capital expenditure required to support this project is spread from the 2024 to 2028 financial years (inclusive) and totals approximately A$128 million. The five-year spread of this capital spend enables Macmahon to maintain a strong balance sheet and enhance return on average capital employed performance, and a number of opportunities exist to optimise this further.

Macmahon said: “The Greenbushes project is in an attractive location, has an existing long-term and loyal workforce with many based in the area. We are eager to engage with them and other people to discuss employment opportunities on the project to build a world-class team. Engaging with the on-site team is a priority for us upon award given the high level of performance we have noted on the project.”

Macmahon CEO and Managing Director, Michael Finnegan, said: “We are delighted to have received the Notice of Award from Talison Lithium for load and haul mining services at its Greenbushes lithium project and look forward to finalising the contract. We very much value the relationship we have forged with Talison Lithium and will continue to build on it. The award of this contract delivers on our commodity diversification strategy into future relevant commodities.”
