Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free.

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 …

Then, the combined column and cell flotation process was proposed based on the optimum conditions of the flotation column process. As described in Figure 3, it was classified into FCSMC–cell-1 and FCSMC–cell-2 according to the treatment of scavenger concentrate.The process consisted of one rougher stage (FCSMC 200 mm × 4000 mm), one cleaner stage …

returned to the mill. because of the high relative sg of gold, and the fact that some forms of gold such as free gold do not break apart during conventional grinding, coarse gold can accumulate in the circulating load, and eventually be lost. eriez has developed a flotation cell that uses fluidized water to enhance flotation of coarse particles.

The depression of pyrite in copper ore flotation is a challenge in high salinity water although natural pyrite can be depressed readily at alkaline pH due to the formation of iron hydroxides on pyrite surfaces (Boulton et al., 2001, Mu et al., 2016).In copper ore flotation, a galvanic interaction occurs between copper minerals and pyrite with copper minerals acting as …
