銅矿石中往往伴生着黄铁矿,也常見有微量輝钼矿,現代选矿技术的发展,不但可以綜合回收銅矿中的黄铁矿,而且可以成功地从銅精矿中分选出高质量的銅精矿。美国在1956年产钼精矿約17500吨,其中1/3就是从銅矿石及鎢矿石中綜合回收得来的。我院曾在一个銅矿石的选矿試驗研究工作中,綜合回收了輝钼矿、含鈷黃鉄矿及磁铁矿等四种合格产品,这里我們将有关回收含鈷黄铁矿和輝钼矿的选矿流程、分离方法以及提高指标,特别是获取含钼50％以上的钼精矿的点滴經驗,做一介紹。
Copper ore is often associated with pyrite, also a trace of molybdenite, the development of modern beneficiation technology, not only comprehensive recovery of pyrite in copper, but also can be successfully selected from the copper concentrate of high quality Copper concentrate. In 1956, the United States produced about 17,500 tons of molybdenum concentrates, of which one-third was recovered comprehensively from copper ore and tungsten ore. Our hospital had a copper ore beneficiation pilot study, the comprehensive recovery of molybdenite, cobalt-rich yellow ore and magnetite and other four kinds of qualified products, where we will be related to the recovery of cobalt-bearing pyrite and molybdenite Beneficiation process, separation methods and improve the indicators, in particular, access to more than 50% molybdenum ore molybdenum bit by bit experience, make an introduction.
