摘要
针对吉林地区某含难选微细粒隐晶质石墨矿进行选矿试验研究,在确定最佳粗选条件基础上,采用一次粗选、粗精矿七次再磨八次精选闭路流程,石墨原矿固定碳含量由11.51%提高至精矿固定碳85.21%,回收率为81.32%。
A beneficiation test of refractory micro-fine aphanitic graphite ore from Jilin area was studied. On the basis of the optimum roughing conditions, a closed trial was conducted by one roughing, then seven-time-regrinding and eight-time-cleaning to the rough concentrate and finally the grade of graphite raised from 11.51 % to 85.21 %, and the recovery of graphite was 81.32%.
