TS矿田某铀矿床矿石矿物学特征研究

The Study of Mineralogical Characteristics of an Uranium Deposit in Taoshan Orefield

指出了TS矿田某铀矿床位于TS铀矿田的中偏南部,矿体赋存于中粗粒斑状黑云母花岗岩中。通过实验对其进行了测试分析,结果表明:该铀矿石矿石矿物成分为沥青铀矿、铀石、钛铀矿和铀钍石;脉石矿物有石英、长石、云母、绿泥石、碳酸盐矿物、绢云母等;金属矿物有黄铁矿、方铅矿、磁铁矿、黄铜矿、闪锌矿;副矿物锆石、金红石、磷灰石等。通过查明铀矿物的存在形式、矿石的结构构造和矿物共生组合等工艺矿物学特征,可以为铀矿石的水冶工艺提供依据。

A medium--sized uranium deposit of Taoshanorefield is located in the sourthern part of Taoshan uranium orefield.The occurrence of ore body is in the coarse grained porphyritic biotite granite.The test analysis results indica- ted that themineralcomponents wereuraninite, coffinite, brannerite and uranothorite. The gangue minerals included chalcedony, chlorite, hydrgmica, fluorite, calcite etc.The metallic mineral included pyrite, galena, sphalerite, arse- nopyrite, chalcopyrite, white ilmenite, hematite zircon, rutile, apatite etc.The uranium mineral is closely associated with sulfide. By finding out the existing form and structureand paragenetic association of minerals of uranium miner- al,this process mineralogy characteristics could provide the basis for the hydrometallurgical process of uranium ore.
