FIELD: gold extraction from chloride solution containing impurities of metals of platinum group, selenium, tellurium, copper, lead, and other metals. SUBSTANCE: precipitation by sugar at 85 to 90 C temperature. EFFECT: decreasing content of impurities of platinum group and non-precious metals in technical-grade gold being precipitated at 0.35 to 0.35 kg (sugar)/kg (Au) and decreasing reduction-oxidation potential of agent down to 650 to 660 mV. 1 tbl
