Prevention of copper dissolution during cyanidation of gold ores .
A process for treating copper containing precious metal ores prior to cyanidation and recovery of the precious metal eg gold. The process involves addition to the ore before or after milling of a water soluble or water dispersible surface active agent in the form of a fatty alkyl amine preferably an ethoxylated fatty alkyl amine. The agent reduces the high cyanide consumption, which is caused by copper .
TwoStage SART Process: A Feasible Alternative for Gold .
The SART (sulfidization, acidifiion, recycling, and thickening) process (SP) has been successfully implemented in gold cyanidation plants to address issues associated with high cyanidesoluble copper content ores. However, this process could produce a relatively low grade precipitate, decreasing the sale price when gold plants have high zinc and copper content in their solutions. A potential option in this .
Processing of Gold Copper and Copper Gold Ores with .
The processing of gold copper and copper gold ores can be highly problematic, site specific and the process selection is dependent on ore grade, mineralogy, acid leach behaviour, cyanide chemistry, product saleability and environmental considerations. The production of a copper gold concentrate is also an option where the copper is of a marketable grade. In some situations the flotation tailings may .
