An overview of the beneficiation of iron ores via reverse

10, 2014 · Research regarding iron ore flotation began in 1931, demonstrating that reverse cationic flotation is a very efficient method for beneficiating oxidised iron ores. This method can also be applied to reduce the silica content in magnetite concentrates obtained using wet lowintensity magnetic separation.

A copper ore is a mixture of copper minerals and other materials in the rock called gangue, from which it is economically viable to extract the metal. A typical copper ore contains between 0.5% and 2.0% copper. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal.
