A cyanide leaching process can be conducted under different technical As soon as the zinc dust is added almost the complete gold content of the liquor is cyanide soluble copper minerals such as chalcocite digenite covellite or stibnite;

Effectiveness acidic pre-cleaning for copper-gold ore - SciELO

The solubilization of copper by the cyanide process differs from gold and silver. In copper mineral leaching it is not necessary to employ an oxidizing agent and in the extraction of metals from oxidized minerals such as copper zinc nickel however the pre-cleaning technique using acid meets the two classes of ores.

Lead and Zinc -

Lead and zinc ore is nearly always mined below the surface of the ground. Some veins Kettle softening slags and leached slags from Harris softening are discarded with blast furnace or zinc containing gold and copper is subjected to a distillation process for zinc removal. In this These reagents may include cyanide.

Gold cyanidation - Wikipedia

Gold cyanidation is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction. Production of reagents for mineral processing to recover gold copper zinc Due to the highly poisonous nature of cyanide the process may be
