With environmental concerns increasing, heavy metal-containing effluent from the mining and electroplating industries is under much more stringent government control. Electrowinning is a means by which the residuary metals from waste-water streams are recovered to be re-used or sold.
The metals that can be recovered by this method are copper (Cu), nickel (Ni), zinc (Zn) and cobalt (Co), and used in the recovery of cyanide-based electrolytes of gold (Au), silver (Ag), copper (Cu), zinc (Zn) and cadmium (Cd)- cyanide is electrochemically destroyed, due to the enhanced anode efficiency.
Different metals plate out at different voltages, so application of the different voltages will allow all metals to be recovered from a mixed metal effluent. Our Mixed Metal Oxide and Platinised Titanium Anodes have already gained acceptance in the Metal Electrowinning Industry and become the anodes of choice. This technology has all but replaced lead anodes offering a far cleaner alternative together with significant power and cost savings.
The CHEMELEC™ metal recovery system can also be used for the efficient recovery of metals from dilute solutions where conventional electrolysis (the driving of a non-spontaneous reaction with DC to discharge ions into electrolyte) cannot be considered.
NMT® also manufactures Mixed Metal Oxide Anodes for other metal recovery systems and fabricate these anodes to customers’ specifications.
