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

The lithium content of ocean water is far lower, hovering around 0.17 parts per million. However, about 20 percent of the lithium in seawater can be recovered using a combination of membranes, filters, and ion-exchange resins. Brine mining is normally a lengthy process that takes anywhere from eight months to three years.

Zinc smelting - Wikipedia

Zinc is extracted from the purified zinc sulfate solution by electrowinning, which is a specialized form of electrolysis. The process works by passing an electric current through the solution in a series of cells. This causes the zinc to deposit on the cathodes ( aluminium sheets) and oxygen to form at the anodes.
