FIELD: metallurgy. ^ SUBSTANCE: complex includes bay of slag preparation successively consisting of furnace, crusher, magnetic separator, vibration screen, and accumulator of processed slag. Also, the accumulator of processed slag is connected to a mixer-separator of the bay for preparation of zinc containing stock, an input of which is parallel connected with industrial water, chemicals, return water, return solution and a heat source, while an output is connected to the bay for preparation of fine dispersed brass to re-melt. The bay for preparation of fine dispersed brass consists of a drier of brass and of moulding device connected to the furnace. The bay for separation of zinc oxide and copper oxide consists of the mixer whereto chemicals are introduced and of filter for separation to copper oxide and to solution containing zinc oxide. The filter of separation to copper oxide and to solution containing zinc oxide is successively connected to a crystalliser, to the filter of separation of zinc oxide from solution returned to the mixer-separator of the bay for preparing zinc-containing stock, to a mixer-separator of washing, to the filter of separation of zinc oxide from water coming to rotation into the mixer of the bay for preparation of zinc containing stock. ^ EFFECT: non-waste processing industrial waste producing brass, zinc oxide and copper oxide at minimal number of process operations and minimal consumption of power. ^ 1 dwg |
