The Lithium Mining Process
The hard rock lithium mining process uses the following steps: After the ore is mined, it's crushed. The crushed mineral is then cooked in a dry heat at 2012°F (1100°C). Once cooled to 140°F (65°C), it's re-milled and cooked again at 482°F (250°C), treated with sulfuric acid in a process called acid leaching.
