Gold in porphyry copper deposits: its abundance and fate,
01-10-2002· 1.. IntroductionPorphyry copper deposits contain up to 100 t of gold and are among the largest reservoirs of gold in the upper crust (Kerrich et al., 2000).They are commonly surrounded by deposits and country rock containing gold that is thought to have been derived from them (Jones, 1992).Gold can be removed from porphyry copper systems by vapors thatGold Tailings Reprocessing Technology,The gangue minerals are mainly quartz, sericite, etc. The processing technology uses one-stage grinding, preferential flotation process. The gold and copper concentrate product can be recovered once. In general, the gold recovery method of gold tailings is mainly the all-slime cyanidation CIP method.SART Process for Gold Recovery and Cyanide Management,,The cyanide is regenerated as free cyanide and recycled to the gold extraction circuit.

The leaching and adsorption behaviour of gold ores
gold was completely extracted by cyanide alone. The flotation feed and copper concentrate showed an enhancement in gold extraction due to the activated carbon adsorbing gold that would otherwise have been preg-robbed. However, this mechanism did not explain the behaviour of the pyrite concentrate. For this ore the,,,,,
