摘要
为进一步提高广东某铅锌矿的铅锌硫的回收率,通过镜下鉴定、X射线衍射分析、扫描电镜分析和MLA(矿物参数自动分析系统)测定对原矿中铅矿物、锌矿物和硫矿物的种类、嵌布特征、解离度进行了全面的检测,检测结果表明:该矿主要有用矿物为方铅矿、闪锌矿和黄铁矿,同时还含有少量镉、汞、锗和银;脉石矿物主要为石英、方解石和白云石;黄铁矿含量较高;铅锌矿物与黄铁矿连生紧密,并且铅矿物有一定的氧化现象。通过对该铅锌矿进行工艺矿物学研究,为后期试验的开展提供了理论依据。
In order to further promote the recovery rate of certain lead-zinc ore in Guangdong.The characteristics of this lead-zinc ore were studied by microscopic observation,scanning electron microscopy,X-ray diffraction and mineral automated quantitative mineralogy（MLA）.The output form of main mental minerals,the disseminating characteristic and the single separation degree were researched.Statistical results show that the main valuable minerals are galena,sphalerite and pyrite.It also slightly contains Cd,Hg,Ge and Ag.The pyrite is abundant in this kind of ore.The galena and sphalerite are closely connected with the pyrite.The lead mineral was oxidated in a degree.By studying the process mineralogy of the lead-zinc ore,the theoretical foundation can be offered to give the direction of the experimental research.
