Equipment for electrodeposition of gold or gold alloys.

摘要

Equipment for the electrodeposition of gold and gold alloys, comprising an electrolytic cell (1) with an anode (10, 11), a cathode (12) in which the objects that are placed to be deposited gold or alloy, and an alkali-cyanide electrolyte, and means to replenish the gold consumed in the electrodeposition process, said means to replenish gold comprise an auxiliary electrolytic cell (2), connected with the electrolytic cell (1) which is made the electrodeposition process by respective ducts (17, 18) allowing recirculation of electrolyte from one to another, said auxiliary electrolytic cell (2) comprising an anode (21) in which gold foils (22) are placed characterized by fact that the distance between the outer part and the inner part of the anode (10, 11) of the electrolytic cell (1) is shorter in the central area than at the upper and lower ends, by the fact that the inner part (11) anode áreamayor has a factor that the outer part (10) and by the fact that the cathode (12) is placed closer to the inner part (11) of the anode of the outer part (10).
