The beneficiation of lithium minerals from hard rock ores

The close similarity in chemical and physical properties between lithium minerals and associated gangue minerals complicates the beneficiation of lithium minerals from ores. Surface chemistry of minerals, type of collector, pulp pH, chemical pre-treatment methods, and the presence of slimes play key roles in lithium minerals flotation.

A review of the beneficiation of rare earth element

2013-2-1  Highlights Review conducted of RE mineral beneficiation using English and Chinese language sources. Of the 250 known RE minerals only bastnäsite, monazite and xenotime are extracted commercially. Flotation, using fatty acids or hydroxamates, is the primary separation process for RE minerals. Currently, optimal beneficiation processes employ flotation, gravity and magnetic separation.

Talc is a naturally hydrophobic gangue mineral in most sulfide ores. However, talc has vast applications in the cosmetics, paper, and paint industries due to its high chemical stability, and its demand continues to grow. Since flotation is the most effective beneficiation technique for upgrading sulfides, the high hydrophobicity of talc has made its selective separation challenging.
