Abstract
Bright gold plate, i.e. of at least 23 Kt, is electro-deposited from a bath containing an alkali metal gold cyanide and a chelate derived from a base or noble metal compound, e.g. of nickel cobalt, copper, cadmium, zinc, indium, tin, arsenic, antimony or silver, and heptonic acid or gluconic acid, the bath including a buffering agent such as acetic, citric, tartaric, lactic or kojic acids. The pH may be adjusted by addition of ammonia, and the bath may also contain potassium pyrophosphate or sulphamic acid. The anodes used may be of platinum, platinum-coated titanium or stainless steel.
