Abstract
In this investigation, an attempt has been made to study the adsorption of gold from dilute solutions on to copper sulphide. It was observed that gold is adsorbed on copper sulphide at low pH; 1 g of copper sulphide has the capacity to adsorb 400 mg of gold. This was then recovered by the zinc cementation method. The adsorption is also dependent on the concentration of gold in solution. Recovery of gold of 100% can be achieved from any solution. The method can be used for the extraction of gold from its minerals. Copper, iron, molybdenum, chromium are not adsorbed on copper sulphide at low pH while silver is adsorbed along with gold.
