Abstract
The invention relates to hydrometallurgy of noble metals. The claimed method comprises anode dissolution of alloys containing noble metals, including gold, and subsequent reduction of gold on a cathode using an electrolyte consisting of dilute sulfuric acid, ammonium nitrate and sodium chloride. The technical result of the invention is selective production of noble metals, including gold, having a high degree of purity, from anode material of various compositions. The method is characterized by low costs for the reagent base used, a decreased volume of process waste and a simplified procedure for recycling the waste.
