一、炼锌窑渣和浸出渣处理的现状炼锌工业的挥发窑渣中尚含有一定量的锌、铅、铜、铟、锗、镓、银等有价金属,如何最大限度地回收这些金属使废渣得到综合利用,已成了炼锌工业的重大课题。窑渣的处理,国内外都进行过多年的试验研究,但至今还没有找到一个尽善尽美的办法。如苏联的贝洛夫斯基炼锌厂采用高温氯化法处理窑渣,也只是半工业试验,始终未能在工业上大规模采用。再是以热酸浸出为基点处理锌浸出渣的黄铁矾法、针铁矿法,也仍然没有完全解决含铁废渣的综合利
First, the status of zinc slag and leaching residue treatment Zinc slag industry in the volatile residue still contains a certain amount of zinc, lead, copper, indium, germanium, gallium, silver and other valuable metals, how to maximize the recovery of these metals So that the comprehensive utilization of waste residue, zinc has become a major issue of the industry. Kiln slag treatment, both at home and abroad for many years of experimental research, but so far still not found a perfect way. For example, the use of high-temperature chlorination for the treatment of kiln slag by the Belovsky smelter in the Soviet Union is only a semi-industrial test and has not been applied on a large scale in industry. And then based on hot acid leaching zinc leaching residue treatment of the iron ore method, goethite method, but also still not completely solve the comprehensive iron-bearing waste
