【摘要】：为了确定澳大利亚布朗斯地区炭质页岩铜钴镍矿资源合适的选矿工艺,对该地区有代表性矿样开展了工艺矿物学研究。结果表明:1矿石为典型的沉积型炭质页岩多金属矿,矿物组成复杂,主要金属矿物为黄铜矿、斑铜矿、硫钴镍矿等,矿石中钴、镍等有价元素以类质同象的形式或呈机械夹杂物分布于硫镍钴矿、黄铁矿及脉石矿物中,脉石矿物主要为炭质、白云母、多水高岭石等。2矿石中各矿物间共生关系复杂,普遍存在着交代结构和相互浸染构造,致使部分可浮性较好的炭质矿物易浮选进入硫化矿精矿中,同时部分微细粒硫钴镍矿被黄铜矿包裹,浮选时易进入铜精矿中。3矿石中黄铜矿和黄铁矿属中细粒嵌布范畴,硫镍钴矿属细粒—微粒嵌布范畴。根据矿石工艺矿物学特征,建议采用阶段磨矿—阶段选别的工艺依次回收铜、钴、镍、硫,尾矿可作为钾化肥。
[Abstract]:In order to determine the suitable mineral processing technology for copper, cobalt and nickel ore resources of carbon shale in Bronx, Australia, the technical mineralogical study of representative samples in this area was carried out. The results showed that the 1 ore was a typical sedimentary carbonaceous shale polymetallic ore with complex mineral composition, the main gold genus was chalcopyrite, porphyrite, sulphur, cobalt and nickel ore and so on. The valence elements such as cobalt and nickel in the stone are distributed in the form of the homogeneous image or the mechanical inclusion in the sulphur nickel cobalt ore, the pyrite and the gangue minerals. The gangue minerals are mainly carbonaceous, the muscovite and the multi water kaolinite are complex in the.2 ore, and there is a common metasomatism and mutual impregnation structure, which results in better floatability. The carbonaceous minerals are easily floatated into sulfide ore concentrate, while some micro fine-grained cobalt nickel ores are wrapped in chalcopyrite. When floatation is easy to enter the fine particle embedding category of chalcopyrite and pyrite in the.3 ore of copper concentrate, the sulfur nickel cobalt mine is fine particle size distribution category. According to the mineralogical characteristics of the ore process, the stage grinding stage is suggested. In order to recover copper, cobalt, nickel and sulfur, the tailings can be used as potassium fertilizer.
