Gold Tailings Reprocessing Technology

The processing technology uses one-stage grinding, preferential flotation process. The gold and copper concentrate product can be recovered once. In general, the gold recovery method of gold tailings is mainly the all-slime cyanidation CIP method. It is the recovery of residual gold particles from tailings by using the property of gold soluble in cyanide. The gold recovery for large capacity ...

Ultimate Guide for Gold Cyanidation Process

Although gold cyanidation process is the main gold extraction method at present, there are still some raw gold minerals that are not suitable to be treated by gold cyanidation process. If the content of copper, arsenic, antimony, tin, sulfur, phosphorus, magnetite, pyrite and other components in the ore is high, the consumption of cyanide and the consuming of oxygen in the ore slurry will be ...

Copper production environmental impact

The copper-bearing solution, from the solvent extraction operations, is plated into pure copper cathodes using a process called solution exchange electrowinning (SX-EW). Stainless steel blanks are added to the plating tanks to act as cathodes and copper is plated onto them by electro-chemical deposition. It takes about a week before the cathode is ready to be removed from the tank so the ...
