Mineral separation by froth flotation is widely used around the world for the beneficiation of sulfide ores. Flotation products (typically concentrate) are subjected to metallurgical processes for metal extractions. Bioleaching as a metallurgical procedure indicated many advantages over other traditional techniques (pyro- and hydro-metallurgy).

All copper sulfide ores are concentrated using the froth flotation process. Ground ore is mixed with xanthate reagents (for example, pine oil), which reacts with the copper sulfide mineral to make it hydrophobic on its surface. The sulfide ore is crushed and ground to increase the surface area of the ore for subsequent processing.

Effective flotation collector reagent selection is dependent on the sulphide minerals present, their mineral associations in the ore, and circuit characteristics. Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance.

Bulk sulphide flotation is a widely applied process because it is an economic method to pre-concentrate gold when expensive pre-treatment or pre-oxidation processes are required. Gold flotation is also applied for the processing of some very low grade ores as well as when liberated fine gold is not arrested by gravity concentration equipment.
