Types and Common Problems of Gold Extraction Equipment. The cyanide gold extraction process is one of the most widely used gold ore beneficiation processes in gold recovery. The cyanide gold extraction process can be divided into many types, and different cyanide gold extraction processes differ in the use of gold recovery equipment.
carbon as a sodium or calcium/gold cyanide ion pair (2) is desorbed from the carbon by a reversal of the adsorption kinetics. Gold is recovered from the pregnant strip solution by electrowinning onto steel wool. The gold depleted solution is then reheated and recycled to the carbon bed for reuse (see Figure 1).
