Extraction of Lithium from Brine—Old and New Chemistry
for the calcium (brine and added) Na 2 CO 3 + 2Li + → 2Na + + Li 3 CO 3. for the lithium. If the resulting lithium carbonate is not pure enough, it can be purified by re-dissolution in water and carbon dioxide [ 7 ]. The carbon dioxide converts the carbonate to bicarbonate, thereby dissolving the lithium carbonate.

How to make lithium extraction cleaner, faster and cheaper
Conventionally, rocky ores are roasted at 1,100 °C and then baked in acid at 250 °C to liberate ('leach') lithium in its sulfate form (Li 2 SO 4) 7. A similar procedure is used for clays 8 ...
How is Silver Mined?
During the 1970s, the mining industry began to develop methods of deep-sea mining. This technology extracts nodules from the floor of the Pacific Ocean rich with copper, manganese, nickel, and Silver, in addition to a variety of other metallic elements. While this technology is promising, traditional methods of mining are still more common.
