摘要:
为了探明广西融水某铜镍矿矿石的工艺矿物学性质，采用光谱半定量分析、化学多元素分析、物相分析等方法，对矿石的物质组成、铜镍在矿石中的赋存形式及黄铜矿、镍黄铁矿的嵌布特性等进行了系统研究.结果表明：该铜镍矿石铜的品位为0.83%，硫化铜中的铜占96.02%，主要赋存于黄铜矿中；镍的品位为0.52%，硫化镍中的镍占73.08%，主要赋存于镍黄铁矿中，但氧化镍和硅酸镍的存在会影响到镍的回收率，其中氧化镍采用常规的浮选药剂是较难回收的，而硅酸镍是不能回收的，所以实际上25.00％的镍是不能回收的.矿石的结构较复杂，矿石中的镍黄铁矿、黄铜矿的粒度以细粒为主，且镍黄铁矿、黄铜矿、磁黄铁矿、黄铁矿之间共生关系密切，多数以非自形晶结构为主，接触边界不规则，给硫化矿物之间的分离带来困难，从而影响铜镍精矿品位.
Abstract:
To explore the process mineralogical properties of a copper nickel ore in Rongshui of Guangxi, a systematic investigation about its mineral composition, copper and nickel occurrence mode and magnetite dissemination was made by spectral semi\|quantitative analysis, multi\|element chemical analysis, chemical phase analysis. The results show that copper grade of the copper nickel ore is 0.83%,and the content of copper in chalcopyrite which is occurred in copper sulfide minerals is 96.02%;nickel grade of the copper nickel ore is 0.52%, and the content of nickel in pentlandite which is occurred in nickel sulfide minerals is 73.08%. However, the existence of nickel oxide and nickel silicate affects the recovery rate of nickel, among which nickel oxide is hard to recover by using normal flotation agents, while nickel silicate is impossible to recover. As a result, 25% nickel is actually not capable of being recovered. The composition of the ore is complicated, in which pentlandite and chalcopyrite have small grain size in general. Also there exists a close symbiotic relationship between pentlandite, chalcopyrit, pyrrhotite and pyrite, most of which have non\|euhedral crystal texture with irregular boundary, bringing unfavorable effect on the separation of suffides.
