摘要

FIELD: technological processes, mining.;SUBSTANCE: invention may be used for processing of zinc-containing wastes of metallurgy and mining production, in particular, zinc-containing blast furnace, converter, electro-steel-smelting dusts and slags, and also zinc and iron containing oxide wastes of ferrous and non-ferrous metallurgy. Method of zinc-containing dusts and slags processing in metallurgy and mining production includes stacking of dusts and slags in ash-and-slag collectors and their processing. Processing is performed by means of disintegration of initial raw material into rotation-pulsation-cavitation device of continuous action with ratio of solid to liquid of 1:4 and at excessive pressure of 5 atmospheres at the inlet to device. Further supply of material into flotator with extraction of zinc, as harmful impurity in foam product and chamber product sent to gravitation classification. in which fine and large-scale fractions are extracted and sent separately to wet magnetic separation in separators with permanent magnets with preparation of conditioned iron-containing concentrate purified from zinc and final tailings.;EFFECT: increase of efficiency of zinc-containing wastes processing and reduction of ecological load in places of concentration of harmful wastes of metallurgy and mining production.;1 dwg
