In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure.Highly oxidized ores generally do not respond well to flotation.Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized.
The major ores of gold contain gold in its native form and are both exogenetic (formed at the Earth’s surface) and endogenetic (formed within the Earth).The best-known of the exogenetic ores is alluvial gold.
In most cases, gold flotation process is used in the treatment of gold-bearing ores with high reproducibility of sulfide minerals with good separation effect.The gold flotation process can not only enrich maximum gold into the sulphide mineral concentrate, but also discard the tailings, so the processing cost is low.
