Concentration of Ores: Hydraulic Washing, Froth Flotation …

Concentration of Ores. An ore of a metal is an impure source, this means other than the metal it consists of many other impurities such as sand, grit, clay, rocks etc. These impurities are collectively known as gangue. Gangue is generally commercial valueless and we must separate it from the ore. This entire process is the concentration of ores ...

 · The cleaned concentrate is thickened and then passes to an agglomeration stage followed by drying. In resin-rubber flotation the slurry fed to flotation contains its own frothing and collecting reagents. Frothing depends on the pH of the washing cycle and pulp density for flotation is less than 2% solids.
