摘要:
四川攀枝花地区有大量钒钛磁铁矿资源,该资源的硫化物中伴生有钴、镍、铜等有价金属。采用激光显微光谱分析、光谱半定量分析和电子探针定量分析等手段,对攀枝花地区钒钛磁铁矿中的硫化物进行详细的工艺矿物学研究,查明了矿石中硫化物的物质组成、主要硫化物矿物嵌布特性和主要有益元素赋存状态等。工艺矿物学研究结果,攀枝花地区的钒钛磁铁矿中硫化物主要为磁黄铁矿,其次为黄铜矿、黄铁矿、镍黄铁矿等,磁黄铁矿是钴、镍、铜等有价元素的赋存物,同时分析了该矿区不同矿段的硫化物特征及选矿产品中硫化物的走向等,研究结果可作为该钒钛磁铁矿的硫化矿中钴、镍、铜的合理开发利用的基础参考依据。
Abstract:
There is a large amount of vanadium titanium magnetite resource in Panzhihua area. Sulfide in the resource is associated with cobalt,nickel,copper and other valuable metals. In this paper sulfide had been investigated by the laser micro spectral analysis,spectral semi-quantitative analysis and electron probe quantitative analysis method in vanadium titanium magnetite in Panzhihua region via the process mineralogy in order to find out the composition of sulfide,the main sulfide minerals distribution and major valuable elements distribution state,etc. According to the results of process mineralogy investigation,sulfide mainly distributes in pyrrhotite,secondly in chalcopyrite,pyrite and nickel pyrite. Pyrrhotite contains cobalt,nickel and copper elements. Besides,the characteristics of sulfide in the mining area of different ore block and the course of the sulfide in dressing products have been gained. Research results are expected to help to achieve the reasonable development and utilization of the vanadium titanium magnetite sulfide ore of cobalt,nickel and copper.
