摘　　要：采用电子显微镜、人工重砂鉴定和电子探针等手段,对华阳川多金属矿床铀矿石进行了工艺矿物学研究。查明矿石中的铀主要赋存于铌钛铀矿中,少量存在于铀钍石、沥青铀矿中;铌钛铀矿多呈粒状及其集合体状分布,与长石、角闪石、黄铁矿、沥青铀矿等密切共生;矿石中有害矿物组分主要是方解石和黄铁矿,二者含量较高,应去除后再浸出,可减少试剂消耗。Electron microscope,manual heavy mineral identification and electron probe methods are employed in the identification process in the huagyang Chuan polymetallic deposit.Occurrence state of uranium is mainly existed in betafite,little existed in uranothorite and pitchblende.Betafite has granular shape and its aggregated distribution.It is closely associated with feldspar,amphibole,pyrite and pitchblende.The harmful compositions in the mineral are calcite and pyrite with high content.In order to reduce reagent cost,both are need removed from the ore before leaching.
