    Commercial Lithium Production and Mining of Lithium

    Aug 27, 2019 · In contrast to salar brine sources, extraction of lithium from spodumene and other minerals requires a wide range of hydrometallurgical processes. Because of the amount of energy consumption and materials required, this is a much more costly process than brine extraction, even though these deposits have a higher lithium content.

    The final recovery step may involve precipitation, cementation, or an electrometallurgical process. Sometimes, hydrometallurgical processes may be carried out directly on the ore material without any pretreatment steps. More often, the ore must be pretreated by various mineral processing steps and sometimes by pyrometallurgical processes.

    Hydrometallurgy - Wikipedia

    Hydrometallurgy is a method for obtaining metals from their ores. It is a technique within the field of extractive metallurgy involving the use of aqueous chemistry for the recovery of metals from ores, concentrates, and recycled or residual materials. Metal chemical processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy and molten salt electrometallurgy.
