Aug 15, 2019· A total of 73 gold grains were observed in the flotation concentrate, including 50 liberated grains, 3 attached and 20 locked grains. According to the electron microprobe analysis, gold occurs mainly as native gold, with minor amounts of calaverite and petzite.

The ground ore is then floated to produce a gold rich copper concentrate for filtration and sale to overseas smelters. Flotation tailings are then leached for further gold recovery. The ore processing rate is approximately 35 million tonnes per annum. Typical head grade is approximately gram per tonne gold and per cent copper.

Recovery of gold in sulfide ores has fallen into several categories. First is froth flotation, and second is cyanidation of the ores. Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery.

In ores where the valuable mineral(s) have a much higher specific gravity than the gangue minerals – eg most sulphide ores, PGM, gold ores – the recirculating load of these higher specific gravity minerals will be substantially higher than the rest of the ore. Also as flash flotation concentrate is produced from the cyclone underflow it

For vein gold ore with high arsenic and sulfur or high carbon argillaceous, the gold sulfide concentrate can be obtained by the froth flotation, and then the flotation concentrate can be recovered by the thiourea leaching process. Thiourea gold extraction is a kind of increasingly sophisticated gold extraction method with low toxicity.
