近几年来,有色金属研究院和有色金属设计院在改善原料的综合处理方面,做了许多工作。许多企业跃进了或重新组织了原料的综合利用工作。例如,乌斯特卡明诺戈尔斯克铅锌联合企业,从精矿中回收了12种纯金属及其半成品的贵重组份;提高了生产硫酸用的硫的利用率;完全掌握了鼓风炉渣的处理方法,即煤尘还原吹炼法,从而使回收到升华物中Pb的回收率达到92％,Zn达到85％。在这种情况下,废渣中只残留约0.01％的Pb和1～1.5％的Zn。在
In recent years, the Nonferrous Metal Research Institute and the Nonferrous Metal Design Institute have done a lot of work in improving the comprehensive treatment of raw materials. Many companies have leapt or reorganized the comprehensive utilization of raw materials. For example, the Ustka-Kamognogorsk-Zink-Zumba conglomerate recovered 12 precious metals and their semi-finished components from their concentrates; increased the utilization of sulfur for the production of sulfuric acid; fully mastered blast furnace slag Of the processing method, that is, coal dust reduction blowing method, so that the recovered to the sublimation of Pb recovery rate of 92%, Zn reached 85%. In this case, only about 0.01% of Pb and 1 to 1.5% of Zn remain in the waste residue. in
