Abstract
Replenishing of gold is carried out by continuous recirculation of the cyanide-alkaline electrolyte between the electrodeposition electrolytic cell (1) and an auxiliary electrolytic cell (2) in whose anode (21) are placed gold sheets (22) so that free potassium cyanide formed in the electrolyte as a consequence of electrodeposition process, combines with gold in said auxiliary electrolytic cell (2) to produce the cyano-complex (K(Au(CN)2). The equipment comprises an electrodeposition electrolytic cell (1) and an auxiliary electrolytic cell (2) that allows the continuous replenishing of gold. The features of the invention allow to produce an electroplate of uniform thickness and composition, keeping the costs, especially those of replenishing gold, at a low level. <IMAGE>
