摘　　要：对甘肃某稀有多金属矿进行了系统的工艺矿物学研究,查明矿石中稀土总量约为2.1%,稀土元素主要为镧系元素Ce、La,少量Nd、Pr,微量Dy、Sm、Tm、Eu、Gd、Tb、Y、Lu、Ho,矿石为低品位稀土矿,稀土矿物主要为氟碳钙铈矿,其次为氟碳铈矿和独居石。矿石中的稀土矿物嵌布复杂,稀土颗粒单晶细小,属较难处理的矿石类型。A systematic process mineralogy study of a rare polymetallic ore in Gansu Province has been carried out.It is found that the total amount of rare earth in the ore is about 2.1%,and the rare earth elements are mainly lanthanide elements Ce,La,followed by a small amount of Nd,Pr,and trace Dy,Sm,Tm,Eu,Gd,Tb,Y,Lu and Ho.The ore is low-grade rare earth ore,and the rare earth minerals are mainly bastnaesite,followed by bastnaesite and monazite.The rare earth minerals in the ore are complicated to be inlaid,and the single crystal of the rare earth particles is small,which is a kind of ore difficult to deal with.
