In addition to non-ferrous metals, old flotation tailings may be a source of ferric iron, which is strong oxidant that can be used for the leaching of non-ferrous metals from different raw materials and wastes including slags, substandard concentrates, and electronic wastes [10, 12-14].
Materials and Methods Samples of old pyrite flotation tailings obtained at an industrial concentrators in Russia were used.
