Flotation of gold and gold-bearing ores

Gold particles in an ore deposit will vary in size from large nuggets to particles locked in the crystal lattice of sulfide minerals. These sulfide minerals are referred to as gold carrier minerals and contain trace to minor amounts of gold (Taggart, 1927; Chryssoulis and Cabri, 1990).Often it is found that gold ores are refractory due to the small size of the gold …
