Lithium minerals are usually associated with gangue minerals, such as quartz and feldspar, so the content of lithium oxide in the ore is low. These useful components are enriched through beneficiation to obtain lithium concentrate, which usually includes gravity separation, magnetic separation, flotation, and other processes (Tadesse B et al., 2019).
