Gold Extraction Recovery Processes

The nature fluidity of the agglomerates allows that gold particles can be absorbed in the oil phase, which is 12-27% of agglomerate. Then, rate of gold recovery is not limited by the metallic content of the product. The metallic content of agglomerates is influenced by the gold content, gold recovery, and carbon/ore ratio. For example, it has ...

Refractory Gold Ore Treatment Methods

11/01/2018  An 80 per cent gold recovery was made by the method of treatment described. It is generally known that antimony can be readily volatilized, and by roasting stibnite (Sb2S2) in an oxidizing atmosphere, antimony oxide can be driven off and condensed. At the same time, anyone who has had experience with such roasting knows that it is a delicate process. To begin with it is impossible to drive
