mineral flotation with low gold ore

Rcovery of gold in pyritic ores mine engineer

To my knowledge, this has never been attempted. Generally speaking, cyanide leaching of low grade pyritic ores is economically unsatisfactory in today's market. Low grade ores that do not respond well to cyanide or flotation are generally referred to a quot;refractoryquot; ore. Which usually means that it needs to be roasted to release the gold.

Extraction of Gold, Gold Extraction Process, Gold Ore

Gold mineral flotation normally adopts one stage grinding flotation process, but stages grinding and flotation for ore with uneven distribution. Grinding fineness of gold. For the gold wrapped in sulfide minerals, sulfide ore reaches monomer dissociation; but for the gold with gangue, grinding fineness should reach gold monomer dissociation.

The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. 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.
