The main difference of this system is the absence of a fine-grained material top layer in the bed and the placement of an extended layer with coarse-grained gravel. A typical configuration of the French system includes a primary and a secondary treatment stage (Boutin et al., 1997; Boutin and Lienard, 2003; Molle et al., 2005). A coarse bar screen is

Gravity separation process is used for the concentration of

Thus, the gravity separation process is used for the concentration of hematite. Thus, the correct option is (B) hematite. Note: Calamine is an ore of zinc, chalcopyrite is an ore of copper and bauxite is an ore of aluminium. The gravity separation process is used for the concentration of heavier ores of iron, lead or tin.

Concentration Of Ore By Gravity Sepration

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 concentrat-ion has declined in twentieth century but still on an average higher tonnage
