金川铜镍矿床中典型单矿物的提取

为研究金川铜镍矿代表性单矿物在浮选过程中的行为，认识、掌握和控制浮选过程，分离提取镍黄铁矿、磁黄铁矿、蛇纹石等代表性单矿物。利用双盘带式磁选机、筒式电动磁选机、QXC－1多用磁选仪，进行反复选别、分离，从二矿区富矿中制备了纯度分别为95.61%,95.46%的镍黄铁矿和磁黄铁矿。用磁选和重选联合流程，从金川贫矿中制备以橄榄石（占40％）、蛇纹石（占35％）为主的脉石矿物，橄榄石按化学组成为镁橄榄石，蛇纹石实际上包括了胶蛇纹石、叶蛇纹石和纤维蛇纹石诸变种。

SEPARATING PURE MINERALS FROM JINCHUAN COPPER-NICKEL MINE

In order to research the action of representative minerals in flotation process, and to grasp of process nature for the purpose of well designing and controlling flotation, pentlandite, pyrrhotite, serpentite and olivine are prepared as representative minerals Pentlandite and pyrrhotite of purity 95 62% and 95 46% respectively are separated from the rich ore of Jinchuan Second Mining Area by magnetic separators The gangue minerals mainly consisting of olivine and serpentine are obtained from lean ores by the combination of magnetic separating and gravity concentrating
