中国科学院矿冶研究所自1960年以来,对重介质旋流器选矿进行了研究。1965年3月与广西第二矿务局密切合作,将实驗室試驗、半工业試驗、工业試驗三步并作一步走,在选矿厂成功地进行了工业性試驗。現在試生产已获得成功。所选别的原矿(12～3毫米粒级)中合錫0.80％,鉛0.57％,鋅2.52％;尾 Institute of Mining and Metallurgy, Chinese Academy of Sciences Since 1960, heavy medium cyclone beneficiation has been studied. In March 1965, in close cooperation with Guangxi No. 2 Mining Bureau, laboratory tests, semi-industrial tests and industrial tests were conducted in three steps and one step was taken. Industrial experiments were successfully carried out at the concentrator. Now trial production has been successful. Selected other ore (12 ~ 3 mm grain size) tin 0.80%, 0.57% lead, zinc 2.52%; tail
