mining machine effect of copper in gold leaching

4 Reasons and Solutions of Poor Gold Leaching Effect

2020-6-22  Reason #3: There are cyanide-consuming minerals such as copper and zinc in gold ore. Some gold ores are accompanied by copper and zinc minerals, such as malachite, azurite, pyrocopper and sphalerite (especially oxidized sphalerite), etc., which have high solubility in cyanide solution. While leaching gold, they will “compete” with gold for ...
