Abstract

In the electrolytic recovery of metals from material containing precious metals, e.g. that obtained by fusing goldsmiths' waste, copper and silver are deposited at the cathode as sludge, from which the copper is removed by leaching with dilute sulphuric p acid, preferably after an oxidizing calcining treatment. From the solution copper sulphate is obtained by evaporation and crystallization.
