摘要
德昌大陆槽稀土矿主要稀土矿物为氟碳铈矿，嵌布粒度细，与天青石、重晶石、萤石、褐铁矿共生关系密切。矿物工艺特性研究说明，氟碳铈矿在磁性上与重晶石、天青石有较大差异，在密度方面与萤石、褐铁矿及脉石矿物有较大差异。选矿试验说明磁—重流程优于其它三种流程，可以得到品位ＲＥＯ５１．０８％的优质稀土精矿，回收率为７８．１１％。
The main rare earth mineral of the ore in Dalucao,Dechang is bastnaesite,and its inlaying size is fine.It closely accretes with barite、celestite、flourite and limonite.The research on the mineral technological characteristics shows that bastnaesite is very different from barite and celestite in magnetism,and fluorite,limonite and gangue in density.The experiments on mineral processing illustrate that magnetic-gravitational flowchart overmatches the other three ones and high quality bastnaesite concentration with grade REO51 08%,recovery78 14% can be obtained.
