摘要: 通过工艺矿物学研究,查明了朝鲜某铜镍矿石的矿物组成,铜、镍的赋存形式,矿石的结构、构造及主要有用矿物的嵌布特性,为选矿试验提供了重要依据。研究结果表明,矿石中的铜、镍主要以易浮的镍黄铁矿、黄铜矿形式存在,但其他硫化矿物与镍黄铁矿、黄铜矿嵌布关系密切而复杂,将给铜、镍的分选带来不利影响。

Abstract: The process mineralogy study was made to identify the mineral composition, copper and nickel occurrence forms of a copper nickel ore from North Korea, its structure and texture, and the dissemination characteristics of its main minerals. The results show that the copper and nickel mainly occur in the forms of pentlandite and pyrite that are easy to float. However, other sulfides have close and complex dissemination relation with pentlandite and pyrite, bringing unfavorable effect on the separation of copper and nickel.
