参考之献[1]指出,可用氯化的方法从精矿中回收稀土元素氧化物混合物。参考文献[2]也研究了单一氧化物的氯化。参考文献[3]中将氧化物加碳与氯气进行反应,可用下式表示:Ln_2O_3+3C+3Cl_2→2LnCl_3+3CO2Ln_2O_3+3C+6Cl_2→4LnCl_3+3CO_2对于各个单一氧化物来说,用炭氯化的机理是不同的。参考文献[4]中陈述了几个假设 Reference [1] points out that the rare earth oxide mixture can be recovered from the concentrate by chlorination. Reference [2] also studied the chlorination of a single oxide. Reference [3] in the carbon oxide and chlorine react, can be expressed as follows: Ln_2O_3 + 3C +3 Cl_2 → 2LnCl_3 +3 CO2Ln_2O_3 +3 C +6 Cl_2 → 4LnCl_3 +3 CO_2 For each single oxide, with carbon chlorination The mechanism is different. Several hypotheses are stated in Ref. [4]
