The Greenbushes lithium mine is an open-pit mining operation in Western Australia and is the world's largest hard-rock lithium mine. It is located to the south of the town of Greenbushes, Western Australia.
The Greenbushes lithium mine produces approximately 1.95 million tonnes of lithium spodumene annually. The mine is 250 kilometres south of Perth and 90 kilometres south east of the Port of Bunbury.
The mine is owned and operated by Talison Lithium which as of 2014 became a joint venture partnership between the Tianqi Lithium Corporation and the Albemarle Corporation. At the mine's current size, it can fulfil a third of worldwide demand for lithium spodumene concentrate, which is used to produce lithium hydroxide, a component of lithium-ion batteries.
The mine is estimated to have resources of 8.7 megatonnes (19 billion pounds) LCE and reserves of 6.8 megatonnes LCE. The mine produces the highest product quality and sets the benchmark for chemical-grade specifications of minimum 6.0% Li2O and maximum 0.8% Fe2O3.
The mine was bought by Tianqi Lithium Corporation in 2013. However, Tianqi soon came into financial difficulties and was forced to offload the minority stake in the mine to the competing bidder, the American-based Albemarle Corporation in 2014. The 49% owner, Albemarle Corporation is based in Charlotte, North Carolina, and is one of the world's largest lithium producers.
