Mar 01, 2022Copper Flotation is a beneficiation method based on the hydrophobicity difference of the mineral surface. While the copper mineral is usually in the form of sulfuration exiting in the mineral. Its natural floatability is good, so froth flotation is the main method of extracting copper ore.
