An Overview of the Lithium Supply Chain
As shown in Figure 1, across deposit types, mining ore grades are generally low (1% to 2%), making these uneconomic for transport. As such, ore concentration activities typically occur at the mine site. Concentration of brine mined ore occurs through solar evaporation in successions of ponds to increase the grade.

Lead and Zinc
6 Lead and Zinc. Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue.
