Zero-emission production method for valuable elements vanadium and iron in calcium-process vanadium extraction tailings
The invention provides a zero-emission production method for valuable elements vanadium and iron in calcium-process vanadium extraction tailings. The method comprises the following steps that (A) desulfurization treatment is carried out on the calcium-process vanadium extraction tailings to obtain a graded iron material; (B) after smelting reduction is carried out on the graded iron material, slag adjusting treatment is carried out, and a low-vanadium iron block is obtained; and (C) vanadium alloying is carried out on the low-vanadium iron block. The method has the production characteristics of being simple in operation, clean and green, the national environmental protection requirements are completely met, the recovery effect on the valuable elements vanadium and iron in the calcium-process vanadium extraction tailings is good, the production cost is low, meanwhile, zero emission of slag discharge in the whole process can be achieved, and the method benefits the nation and the people.
本发明提供了一种钙法提钒尾渣中有价元素钒和铁的零排放生产方法，包括以下步骤：A)将钙法提钒尾渣进行脱硫处理，得到选别铁料；B)将选别铁料进行熔融还原后再进行调渣处理，得到低钒铁块；C)将所述低钒铁块进行钒合金化。本发明具有操作简单和清洁化绿色的生产特点，完全符合国家环保要求，钙法提钒尾渣中有价元素钒与铁回收效果好，生产成本低，同时，还可实现全流程渣排量零排放，利国利民。
