镍冶金渣综合利用现状

Comprehensive utilization of nickel metallurgical residue

镍渣是镍冶炼过程中排放的一种工业废渣,含有铁、镍、钴和铜等多种有价金属。由于近年来工业的迅速发展,镍渣产生量随之增多,不仅占用了大量的土地,浪费金属资源,而且严重污染了环境。结合目前镍渣处理及综合利用现状,介绍了镍渣作为矿井充填材料、建筑材料以及有价金属的回收再利用方面的应用,并展望了镍渣综合利用研究的发展趋势。

As an industrial waste slag, nickel slag produced in the nickel smelting process contains many valuable metals,such as iron,nickel,cobalt and copper. With the rapid development of industry in recent years, the output of nickel slag is increasing, which not only takes up a lot of soil and wastes metal resources, but also seriously pollutes the environment. On the basis the current status of the treatment and comprehensive utilization of nickel slag, the applications of nickel slag in mine filling materials,building materials,and recovering valuable metal recycling are introduced, and the development trend of the comprehensive utilization of nickel slag is predicted.
