摘　　要：在高温合金等金属材料切削和打磨加工过程中,有少量金属进入切磨废料中,造成金属损失。采用选矿手段将废料中有用的金属富集回收是一种经济有效的方法。试验主要对某含镍钴合金金属加工磨床废料进行了原矿粒度分析、磁选、重选、浮选探索试验研究。试验结果表明:通过筛分将物料分为200目筛上和筛下两个粒级,筛下物料进行重选可获得符合要求的金属物料。In the process of cutting and grinding metallic materials such as super alloy,a small amount of metal fall off into the cut-ting and grinding waste,causing metal loss.It is an economical and effective way to concentrate and recover valuable metals in a nickel-cobalt-containing metal processing waste by mineral processing method.The experiments mainly carry out studies on particle size analy-sis,magnetic separation,gravity concentration and frothflotation.The results show that the material under the 200 mesh sieve can meets the requirements after gravity separation by sieving the material into two grain levels of 200 mesh sieve undersize and oversize.
