Gravity Concentration of Iron Ore [email protected]

Gravity concentration process is the oldest beneficiation method known to mankind This is a physical process and exploits the differences in densities of minerals to bring about a separation Although with the advent of froth flotation, the relative importance of gravity concentration has declined in twentieth century but still on an average higher tonnage of material is treated by gravity

Gravity Concentration an overview | ScienceDirect Topics

Gravity concentration, or densitybased separation methods, declined in importance in the first half of the twentieth century due to the development of froth flotation, which allowed for the selective treatment of lowgrade complex ores Lucay et al (2012) It is widely used in coal beneficiation, iron ore and diamond processing, and in
