Specifications. Sizes: 100 cu.ft./cell – 600 cu.ft./cell (open flow) = from 2.82 cubic metres to 17 cubic metre
Gold concentration usually consists of gravity separation, flotation, cyanidation, or the combination of these processes. The choice among these processes depends on the mineralogical characterization and gold content of the ore. Recently, the recovery of gold using gravity methods has gained attention because of low cost and …
Application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals, followed by the installation of pyrite flotation plants on …
Initial results were very encouraging. Overall mill gold recovery increased approximately 5%. Typical plant test flash flotation metallurgical results were: FI believes the addition of flash flotation to the grinding circuit has decreased future conventional flotation cell volume requirements for future expansions.
