spodumene ore processing

Commercial Lithium Production and Mining of Lithium

After it is mined, spodumene is heated to 2012 degrees Fahrenheit and then cooled to 149 degrees. It's then crushed and roasted again, this time with concentrated sulfuric acid. 1  Ultimately, sodium carbonate, or soda ash, is added, and the resulting lithium carbonate is crystallized, heated, filtered, and dried.
