In this study, the gold refinery wastewater that contains copper, nickel and zinc in the chloride and nitrate media has been used. Since the wastewater was supplied from the gold refining process, the solution were strongly acidic (pH below 0). In order to adapt the pH for metal extraction firstly caustic solution was added to adjust pH to 1.

Statistically, 30 to 80 percent metal, 5 to 20 percent acid and 2 to 3 percent water are used efficiently in the processes. The most common electroplating processes are zinc, nickel, chrome, copper, cadmium and iron plating, sedimentation of precious metals, and alloys of stannum, lead and bismuth. Part of the metals enter the liquid waste stream.
