BRASS FOUNDRY SLUDGE PYROMETALLURGICAL PROCESSING METHOD

摘要

FIELD: metallurgy.SUBSTANCE: invention relates to brass foundry sludge pyrometallurgical processing. The furnace-charge is prepared, it contains slag, graphitised breeze coke in amount of 10% of slag weight, copper collecting agent, and carbonates of alkaline and alkaline-earth elements as activator of the regenerative process at the copper collecting agent consumption 0.1-0.3 of slag weight. The furnace-charge is melted at 1000-1300°C in induction crucible furnace with located in the crucible induction heater in form of the graphite rod with diameter 0.1-0.2 of crucible diameter or graphite pieces in amount of 1-5% of crucible volume.EFFECT: most complete copper and copper alloy components extraction from the slags with minimum losses of highly volatile element.3 cl, 2 dwg, 14 ex
