Flotation is a benefication 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 flotation is the main method of extracting the copper ore. According to the processing order of the useful mineral, the copper ore processing/mining can be divided into precedence flotation, equivalent flotation, mixed flotation and partial flotation. The process choice of copper ore flotation is determined by the raw ore properties.
Meanwhile, there are many determined factors for copper ore flotation process, like the mineral disseminated particle size, the associated relationship with quartz rock and the gangue mineral types. Only taking full consideration of the factors and using the proper process, it can efficiently recycle the useful copper mineral from the raw ore.
