Study of the Technology for Gold Recovery from …
The majority of gold processing plants currently handle ores containing sulfide minerals. Gold in such ores is par-tially associated with sulfides and partially in a free state. Ores of this type are in most cases classified as refractory. The raw material for gold recovery is the gravity-flotation concentrate of ore enrichment.

The size of gold particles is a crucial factor in ore processing technology. Gold is typically categorized into three size groups based on its behavior in subsequent processing operations: coarse gold, with particles larger than 0.07 mm; fine gold, with particle sizes between 0.07 and 0.01 mm; and finely dispersed gold, smaller than 0.01 mm.
