Abstract Beneficiation of low-grade ore is of critical importance in order to meet the growing demand for coal and mineral industries. But, low-grade ores require fine grinding to obtain the desired liberation of valuable minerals. As a result, production of fine particles makes the beneficiation process difficult through conventional gravity …
For example, gold has a specific gravity of 19.3, which is 19.3 times denser than water. This high density facilitates separation from other minerals by gravity concentration techniques. Gravity concentration is best for coarse particles as …
