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 followed in brine extraction.

Firstly, vanadium cannot be pre-concentrated effectively by the conventional flotation, gravity and magnetic separation methods. For example, Liu et al. used the gravity separation method to treat the stone coal ore, the V 2 O 5 grade can be improved from 0.81% to 1.02% and the recovery rate was 89.6% ( Liu et al., 2016 ).

For iron ore this involves crushing the ore and then concentrating it in different ways, for example by milling, flotation or magnetic separation. At some sites the ore is processed further and pelletised for use in direct reduced iron (DRI) steelmaking. In the processing stage, the mined material is transformed into usable raw material.
