白云鄂博氟碳铈矿-独居石混合精矿中非稀土元素的氯化反应
Carbochlorination of Non- rare Earth Elements in Baiyunebo Mixed Bastnaesite- monazite Concentrate
摘要
Abstract
The isothermal carbochlorination reaction of non-rare earth element in Baiyunebo mixed bastnaesite-mon azite concentrate and the change of its physical states in this process were investigated. When the temperature is 500t ,the non-rare earth elements of Ca,Ba and Mg in Baiyunebo mixed bastnaesite-monazite were carbochlorinat ed completely using carbon as reductant,chlorine as chlorination agent,SiCl4 as defluoration agent. Their carbon chloration products were dissolved in water with the carbonchloration products of rare-earth. TiCl4 mainly exit in the insoluble residues, less than 1 % of which was vaporized in the carbochlorination process and deposited in the recep tors around 450^. FeCl3 was deposited in the receptors at 300t to 150T!. POC13 was deposited in the receptors below 150t. The separation of Fe, P Th from other substances and the separation of a little substance which was not carbonchlorated from carbonchloration products can be realized by dissolved the carbonchloration products in water.关键词
