Difficult to choose gold mine and cyanide tailings gold extraction and its comprehensive utilization technology

The traditional gold extraction method is cyanidation, which produces a large amount of gold smelting cyanide tailings every year, and with the deepening of gold mining, the output of refractory gold mines is getting larger and larger. In order to improve the extraction of gold and reduction of gold cyanide tailings smelting of environmental pollution, the use of catalytic oxidation of refractory gold cyanide tailings, wrapped in gold sulfide, arsenic compounds in the catalytic oxidation of these minerals may be out Increase the chance of gold contact with the leaching agent, thereby increasing the recovery rate of gold. While also integrated recovery of silver, copper, lead and other valuable elements, and the use of large amounts of iron, wherein the recovery of the production of ultrafine. At the same time, it can also comprehensively recover valuable elements such as silver, copper and lead, and use a large amount of iron to produce ultra-fine and transparent iron-based pigments.
