Albermarle gets environmental nod for lithium plant

US-based lithium and speciality chemicals producer Albermarle has received environmental approval for the development of a lithium hydroxide plant near Bunbury in the southwest of Western Australia (WA).

While the company is still awaiting some other approvals before making a final investment decision on the plant, which is allowed to produce up to 100,000 t/yr, approval by WA's Environmental Protection Authority is seen as a major step forward for the proposed project, estimated to cost around A$1bn ($723mn).

Albermarle, headquartered in Charlotte, North Carolina, owns 50pc of Talison Lithium, which owns and operates the Greenbushes mine, the world's largest producer of hard rock lithium concentrate. The other shareholder is China's Tianqi Lithium, which is building a A$700mn lithium hydroxide plant at Kwinana, south of Perth. Albermarle also has significant lithium operations in Chile, the world's largest lithium brine producer.

Albermarle and Tianqi have spent A$320mn on expanding Greenbushes' capacity and are planning to invest a further $600mn to boost lithium concentrate output to 2.3mn t/yr from 2021.

It is expected that Albermarle will develop five lithium hydroxide "trains", each with a capacity of 20,000 t/yr in a staged development over a few years.

Already the world's biggest supplier of hard rock lithium, WA is increasingly becoming a premier location for downstream lithium conversion, with the main focus on lithium hydroxide. Kidman Resources and its joint-venture partner Chile's SQM have announced plans for a 45,000 t/yr lithium hydroxide plant at Kwinana and Perth-based resources firms Neometals and Mineral Resources are also planning plants.

Battery producers are increasingly preferring lithium hydroxide rather than lithium carbonate for cathodes as it gives batteries greater energy density, capacity and longer life. Concentrate from hard rock lithium can be directly converted into lithium hydroxide, while concentrate from lithium brine must be converted into lithium carbonate before it can be made into lithium hydroxide.

The WA government has established a special lithium and battery materials taskforce to take advantage of the state's lithium production status, along with its output of nickel and cobalt.

South Korea's POSCO buys stake in Aussie lithium producer, signs supply deal

POSCO, South Korea's largest steel producer, has inked a deal to buy up to 240,000 tonnes of lithium concentrate per year from Australia's Pilbara Minerals (ASX:PLS), securing this way a constant supply of the key material used in the making of electric vehicle batteries.
