摘要
炼锌渣工业上往往直接排放形成固体废弃物 ;采用选矿工艺回收铁、金银、炭粉 ,尾矿作为水泥熟料填料 ,实现无尾矿工艺 ;综合回收不仅增加企业的经济效益 ,而且有利于保护环境。
Zinc metallurgical slag is often dischar ged as Industrial solid waste. In this i nvestigation, Iron, gold, silver and carbon could be comprehensively recovered f rom the slag by concentration technology. The tailings of the concentration coul d be utilized in cement industry. This technology can benefit both the enterpris e's economic efficiency and the environment protection.
