湿法炼锌浸出沉矾沉铁工艺探讨

Discussion on vanadium and iron precipitation process in zinc hydrometallurgy

比较了常规黄钾铁矾法与低污染黄钾铁矾法沉铁的优缺点,针对常规黄钾铁矾法铁矾渣含锌高以及低污染黄钾铁矾法无法处理高铁原料的问题,提出常规黄钾铁矾法与低污染黄钾铁矾法联合沉铁新工艺。

The advantages and disadvantages of conventional jarosite process and low-pollution jarosite process are compared.As the zinc content in residue is high in conventional jarosite process and high iron-bearing materials cannot be treated with low-pollution jarosite process,a new process with the combination of conventional jarosite process and low-pollution jarosite process is proposed for iron precipitation in this paper.
