FIELD: metallurgy.
SUBSTANCE: method includes blending of concentrate with solid sal ammoniac in portions 100-140% molal from stochiometric amount. The it is implemented heating at temperature 200-320°C and leaching by water with transformation into soldering acid, iron, copper and separation of silicon oxide. Additionally value of pH of solution is developed up to 3. By filtration it is separated ferric hydroxide and is baked up to receiving of ferric oxide. Into the rest solution it is added lack of ammonia water in ratio 70-90% molal from stochiometric amount. By filtration it is separated zinc hydroxide and is burnt up to receiving of zinc oxide. The rest solution is boiled. Then by filtration it is separated copper hydroxide and is burnt up to receiving of copper oxide.
EFFECT: receiving of ferric oxide, copper oxide and zinc oxide, cleaned from admixtures.
