Apr 15, 2018 Gold Pyrite, Pyrrhotite and Arsenopyrite Recovery. One of the more common classes of ores containing gold is when gold is associated with pyrite, pyrrhotite, and arsenopyrite. This is the area of gold recovery that has probably received the most research and plant optimization support especially in light of the long history of South Africanget price

Jan 01, 1991 Abstract. The flotation of pyrite is of great importance to the gold mining industry in South Africa and Australia. The flotation plants fall into a number of categories, viz. flotation after milling, flotation of current residues and reclaimed residues, flotation of refractory ores and the flotation of gold-copper oresget price
Jan 01, 2016 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 numerous gold mines in South Africaget price
In the late 1970s and early 1980s there were approximately 25 pyrite flotation plants operating in South Africa. These were located in the gold mining areas where the slimes dams were retreated mainly to produce a concentrate for sulphuric acid production. The gold content was 0.5g/ton of which about 50% was recovered in the concentrate. Early work in the flotation group focused on a wide range ofget price
