Minerals are oxidized by air during storage, transportation, crushing and flotation. The oxidation of minerals, especially metal sulfide ore, can greatly affect the flotation. Research and experiments have shown that some sulfide minerals will have a better floatability after being slightly oxidized within a certain limit.

Mineral concentration is characterized by two main indicators: content of the useful component in the concentrate and extraction of the useful component (in percent). As of 1974, up to 92-95 percent of the useful components were being extracted. In this case, the concentration of such components increases by factors of 10-100.

The concentrated mineral particles may be detached from the magnetic particles by any suitable method. For example, the flotation reagent may be destroyed with oxidising reagents such as hypochlorite, hydrogen peroxide or air, or by pyrolitic degradation. Alternatively, the flotation reagent may be displaced by ions such as cyanide or hydroxide.
