    Typically, copper-bearing minerals are removed by froth flotation by adding of flotation agent to water suspension of ore materials leading to the sulfide minerals to float to the surface where they can be skimmed off and followed by settling, filtration, and drying (Germani et al., 1981). The elemental fraction somewhat depends on several factors, such as the properties of elements themselves, their
