摘要
为给河南某钼矿资源合理开发利用提供依据,利用国际先进的MLA矿物自动定量分析技术,结合光学显微镜、化学物相分析等综合技术手段对其进行了工艺矿物学分析。结果表明:矿石中主要有用矿物为辉钼矿,其余金属硫化矿为黄铁矿、闪锌矿、黄铜矿,金属氧化物主要为磁铁矿和赤铁矿;辉钼矿以中粗粒级嵌布为主,部分呈星点状和浸染状分布,嵌布粒度较细,需细磨才能单体解离,但细磨容易造成泥化,且矿石中绿泥石、蛇纹石、黏土矿物等与辉钼矿紧密共生,易对辉钼矿浮选产生不利影响。建议采用阶段磨矿阶段浮选流程处理该辉钼矿石。
To develop and utilize talcose-molybdenite ore in Henan reasonably and efficiently,the research on process mineralogy was detailedly investigated by the international automatic quantitative mineral technology MLA combining with the means of optical microscopy,chemical phase analysis,etc.. The results show that molybdenite is the main valuable mineral and the rest of sulfide minerals are pyrite,sphalerite and chalcopyrite. Magnetite and hematite are the main metal oxide minerals in the ore. Most of molybdenite is disseminated in forms of coarse grain in the ore,however,part of molybdenite is distributed in the ore in forms of stellate and disseminated structure,which is very fine and not easy to liberate completely. Fine grinding is necessary,but it is harmful for flotation after fine grinding because clay mineral,chlorite and serpentine are closely associated with molybdenite in the ore. Based on the findings above,it is recommended that the beneficiation adopts the technical route with stages grinding for this ore.
