The beneficiation of lithium minerals from hard rock

2019-1-15  The main gangue minerals found in association with lepidolite include calcite, muscovite, feldspar and quartz, which need to be separated to enrich lepidolite. Flotation can be used to separate calcite, muscovite, feldspar and/or quartz from lepidolite (Choi et al, 2012). Sulphuric acid digestion at temperatures higher than 250 °C is one method used for the extraction of Li from lepidolite.
