摘要
Abstract
A graphite ore belongs to the low-grade and super-fine flake graphite ore,which contains 8.17％ fixed carbon,and the dissemination size of the ore is super fine,some graphite size is even lesser than 10 μm.According to the ore properties a series of conditions test was carried on..And the proper closed Beneficiation process was achieved,which was one roughing grinding,one roughing and one scavenging,then six regrinding and seven cleaning.The results show that finally the graphite concentrate of fixed carbon with the grade of 85.49％ and recovery of 86.95 ％ was achieved through the whole closed-circuit test,which has some reference value for this type of mineral graphite resources utilization.关键词
