The beneficiation evaluation of this ore was conducted based on the mineralogical characteristic, and it indicates that the tantalum-niobium–lithium–rubidium rare metal resources, as well as the feldspar and quartz non-metallic resources in the ore, can be effectively and comprehensively recovered using gravity, magnetic, and flotation ...
The commercial processes of coal beneficiation are based on the differences in some physical properties of the pure coal and the impure coal (refuse). The difference in specific gravity is the basis for the largest number of coal beneficiation processes in which case they are termed as Gravity Concentration Processes.
