一、前言 包头稀土资源十分丰富,但矿物成分复杂,在稀土精矿中除了氟碳铈镧外,还含有独居石15～35％以及萤石、石英、重晶石、方解石、磁铁矿、赤铁矿等多种矿物。采用加碳高温氯化法处理含多种杂质的稀土精矿,可直接生产出符合电解要求的无水稀土氯化物[1,2]。但是包头稀土精矿成份复杂,又给氯化工艺和设备带来许多问题。 I. Introduction Baotou rare earth resources are very rich, but the mineral composition is complex, in rare earth concentrate in addition to bastnaesite, but also contains 15 to 35% monazite and fluorite, quartz, barite, calcite, magnetite, Hematite and other minerals. The use of carbon high temperature chlorination method with a variety of impurities in the rare earth concentrate can be directly produced in line with the requirements of electrolysis of anhydrous rare earth chloride [1,2]. However, Baotou rare earth concentrate complex composition, but also to the chlorination process and equipment to bring many problems.
