云南腾冲铜铁矿工艺矿物学研究

以云南腾冲某地铜铁矿为研究对象,运用化学多元素分析、物相分析、光学显微镜分析等手段,对该矿石的化学组成,铜、铁赋存状态,嵌布粒度进行了详细研究.研究表明,矿石中主要有价元素为铜和铁,品位分别为铜1.79％、铁38.31％.矿石中的铜主要赋存在孔雀石、黄铜矿、斑铜矿中,另有少量铜以结合氧化铜的形式赋存在中磁铁矿中,或呈吸...

Detailed study on technological mineralogy of Copper-Iron Ore in Tengchong of YunNan Province

With copper-Iron ores in Tengchong of YunNan as the study object,by chemical analysis, phase analysis, optical microscope analysis to investigate chemical element composition, phase composition and distribution characteristics of mineral grain size. The results show that the main valuable recovery elements are copper and Iron, the grade of copper and Iron is 1.79% and 38.31%.Copper mainly exists in the form of malachite,chalcopyrite and bornite,a little of copper occurrence State of conjunction oxidized copper in the magnetitl,adsorption state with chlorite or hybrid with gangue,the oxidation rate of copper is 59.86%. Iron mainly exists in the form of magnetite and hematite,a little of Iron occurrence State of isomorphism in the diopside,tremolite,chlorite,garnet and olivine.Process mineralogy research show that the refractory mineral has high oxidation rate of copper,complex occurrence of Iron, may cause low grade and recovery of the concentrate.
