  • Recovery of Gold in Pyritic Sulfide Ores Mine

    Recovery of Gold in Pyritic Sulfide Ores Mine

    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.

    From sulfide ores. Because the conversion of nickel sulfide directly to metal would require an extremely high temperature (in excess of 1,600 °C [2,910 °F]), the removal of sulfur at this stage of the converting process is controlled in order to produce the 70–75 percent nickel matte, which has a lower melting point.

    Processing Sulfide Ores. Instead of relying on autoclaves or roasting to prepare a sulfide ore for traditional leaching, our vibratory grinder on our circuit allows our leach to make contact with the precious metal encapsulated in the sulfide so leaching can occur. With the aggressive nature of our leach allowing us to process most ores in an hour,...
