Gold ores containing high levels of cyanide-leachable copper minerals, such as covellite, chalcocite, bornite, malachite, azurite, and cuprite have traditionally been difficult to treat economically.
Gold ores with nuisance copper differ from free-milling oxide ores in the back-end treatment of the cyanide-leached slurry. Cyanide reacts with copper minerals to form a range of copper–cyanide complexes, thereby consuming more cyanide than is necessary for gold leaching only. ... from both the Cu 2 S thickener overflow and Cu 2 S filtration ...

In the treatment of gold-bearing polymetallic sulfide mineral ores with high content of valuable heavy metals (such as gold-containing polymetallic sulphide ores containing copper, copper, zinc, lead, zinc, antimony, arsenic, etc.), since these ores contain To eliminate harmful factors, in order to eliminate unfavorable factors, in the actual ...
In mining, when flotation is finished with the ore, and a final concentrate has been produced, often, both products will go to a concentrate thickener before it is dried for shipping. This is a very important step so here …
This milestone was the driving force to promote this technology in other mines having the same issue: the high cyanide-soluble copper content in gold ores which limits the profitability of a gold ...
Gold cyanidation methods have played a pivotal role in the modern gold mining industry, enabling the extraction of gold from low-grade ores and contributing to the global economy. While the cyanidation process is highly effective, it is essential to consider the environmental and social implications associated with its use.
The proven and probable mineral reserves at the Taca Taca project were estimated to be 1,758.5 million tonnes (Mt) grading 0.44% copper, 0.012% molybdenum, and 0.09g/t gold, and containing approximately 7.73Mt of copper, 2.13Mt of molybdenum, and five million ounces (Moz) of gold, as of October 2020. Mining methods
For many gold copper ores production of a gravity concentrate from the mill circuit results in the recovery of much of the gold or copper into a relatively small stream. The remaining material …
