The beneficiation of lithium minerals from hard rock ores: …

DMS exploits the difference in specific gravity between the target and gangue minerals, and is commonly used in the separation of spodumene from other gangue silicates. The specific gravity of spodumene is between 3.1 and 3.2; this makes it slightly heavier than most gangue minerals such as quartz (2.65), albite (2.60) and muscovite (2.8).

Pre-concentration of vanadium from stone coal by gravity separation

A new process for pre-concentration of vanadium from stone coal by gravity separation was investigated based on mineralogical study. It was confirmed that the vanadium occurred in muscovite and illite, and the acid consuming minerals were pyrite and calcite.The process comprised three key steps: decarburization, selective grinding and gravity separation.
