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 …

A review of flotation and selective separation of pyrrhotite: …
However, problems arise when a part of non-magnetic, hexagonal pyrrhotite is present in ore samples or when dealing with pyrrhotite entrainments within magnetic ores, such as magnetite and iron-bearing sphalerite [14]. Therefore, flotation is commonly used instead of magnetic separation to achieve the separation of pyrrhotite [15].
