稀土精矿焙烧处理后2000A熔盐电解制取混合稀土金属

Electrolytic Preparation Mischmetal by Roasting - treated Rare - earth Concentrate in 2000A Molten - salt Furnace

本文介绍了以四川冕宁商品稀土矿经再造分所得稀土精矿为原料,经焙烧处理得到高品位稀土精矿,再在2000A氟化物熔盐体系中直接电解制取混合稀土金属的工业性试验情况.

This paper introduces the industrial test of recleaning rare ?earth concentrate which has been won high - grade concentrate by roasting, then it directly was electrolysed mischmetal in 2000A fluoride molten- salt furnace. The results of experiment show that the method is feasible and the better technical and economic indexes has been achieved. The product quality has reached the standard GB/T 4153 - 93.
