摘要: 尾矿资源的再开发利用越来越受到全社会的关注。针对某铜镍矿年排放尾矿量大、尾矿中的镍以细粒单体为主的特点,应用旋流喷射浮选柱对尾矿进行了再选试验研究。在实验室研究的基础上,进一步进行了工业试验,经1次粗选、1次扫选、3次精选后从含镍0.23%的尾矿中得到含镍2.78%,回收率14.02%,MgO含量降至8.25%的精矿产品,取得了良好的技术经济指标。

Abstract: The recovery and utilization of tailings is attracting more and more attention in modern society.In view of large capacity of copper-nickel mine tailings drainage every year in a fine-grained single nickel-based feature,the Swirl Injection Flotation Column was used to do the re-concentration test in laboratory firstly.Then,based on the laboratory tests,the industrial test is made.A nickel concentrate grading 2.78% at a recovery of 14.86% and MgO grading below 8.25% were obtained from the production tailings which have 0.23% Ni by the process consisting of one roughing,one scavenging and three cleanings.
