摘要
为配合云南东川铜、硫、铁多金属矿的矿石可选性试验,开展了该矿的工艺矿物学研究。结果显示,主要金属元素铜、铁、铋、金、银分别赋存于黄铜矿、磁铁矿、辉铋矿、银金矿等矿物中。矿石中的主要金属矿物磁铁矿含量较高,与其他金属硫化物矿物嵌布关系密切,且磁铁矿的嵌布粒度较粗,这对矿石的可选性影响较大。
In order to coordinate with the beneficiability tests of the copper-sulfur-iron polymetallic ore in Dongchuan Yunnan,the research on process mineralogy of the copper-sulfur-iron polymetallic ore is carried out,so as to find out the occurrence states of the five main valuable metals in the test samples. The mineral composition of the ore has been identified. Copper,iron,bismuth,gold and silver exist in chalcopyrite,magnetite,bismuthinite and electrum respectively. The ore has a high content of magnetite which is intimately disseminated among other metallic sulphides and the grain size distribution of magnetite are not fine. This would have a major influence on the beneficiability of the ore.
