金川有色金属公司是我国重要镍基地。为合理利用二矿区富矿,有关单位曾做过不同方案的选矿工艺的试验研究,取得了不少成果。其巾中性介质选矿工艺连续选矿试验,于1981年6月17～26日在冶金部矿冶研究总院进行,由于参加试验人员的共同努力,获得成功。试验表明,所制定的中性介质选矿工艺流程结构简单合理,操作顺利,设备运转正常,选矿指标 Jinchuan Nonferrous Metals Company is China’s important nickel base. In order to make rational use of the ore in the No.2 mining area, the relevant units have conducted experimental studies on beneficiation processes with different plans and achieved a great deal of achievements. The towel neutral medium beneficiation process of continuous dressing test, June 17, 1981 June 26 in the Metallurgical Department Mining and Metallurgy Research Institute, due to participate in the joint efforts of test personnel to be successful. The test shows that the neutral medium beneficiation process has a simple and reasonable structure, a smooth operation, a normal operation of equipment, a beneficiation index
