How Does Lithium Mining Actually Work and Will We Have Enough?

After spodumene is mined, it's heated to 1100°C, then cooled to 65°C and ground up, mixed, and roasted with concentrated sulfuric acid. The sulfuric acid kicks off a reaction in which lithium sulfate replaces hydrogen. The slurry is then filtered and a number of additional compounds are added.

Lode vs. Place Mining | Wells Historical Society

The process of placer mining is the process that is used to find the gold that has been eroded from the lode. Very generally speaking, placer mining involves sifting through gravel to separate the pieces of gold. Placer mining can be done by a single prospector with a gold pan. The process of lode, or hard rock, mining, on the other hand, is ...

The least common method in hard-rock mining, block caving, is typically saved for low-grade ore. It involves drilling a section of ore at the very bottom of the deposit and then blasting to make the roof collapse. Gravity then takes over, as the ore above the blast site fractures and collapses in succession as support is withdrawn.
