Method for processing zinciferous steelmaking dust in the direction of obtaining concentrates of zinc and lead concentrates

摘要

method of processing cynkonou015bnych dusts stalowniczych in order to receive zinc concentrates and lead concentrates, characterised by the fact that leads to selective etching of lead and chloride contained in the ashes stalowniczych via solution - suspension of ca (oh) 2 + naoh concentration ca (oh 2) 1.5 - 2.0%, naoh 0,5 - 1% of the following selective secretion of solutions potrawiennych trudnorozpuszczalnych lead compounds forming rich concentrate lead.then prepares nadawu0119 kiln przewau0142owego by mixing purified from chlorine and lead dust stalowniczych with pressure regulator - koksikiem of 30 - 35% in relation to the weight (dry) stalowniczych dusts and topnikiem in fragmented form of limestone in the il bones to content in the flux nadawie przewau0142owego as cao was 6 - 8% forthe particulate mass stalowniczych. followed by pirometalurgiczne processes przewau0142owych at 1000 - 1300u00b0c, whose product is steel zinc oxide content of the product is steel zinc oxide containing 50% zn, characterised by low lead content and chlorine.
