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 …

Flotation Machine
In the 1970s most flotation machines were of the "open-flow" type, as they were better suited to high throughputs and easier to maintain than cell-to-cell types. The Denver "Sub-A" was perhaps the most well-known cell-to-cell machine, being widely used in small plants and in multistage cleaning circuits.
