What is the process of mining lithium from evaporating ponds? Mining lithium from evaporating ponds is a unique method of lithium extraction. It involves pumping lithium-rich brine into large evaporation ponds and allowing the water to evaporate over time. The concentrated brine is then processed to extract lithium, similar to the process ...
