摘要
针对湿法炼锌过程中 ,常规的铁矾法、喷淋法等除铁工艺存在渣量大、周期长、能耗高以及渣二次污染等缺陷和不足 ,并借鉴国外除铁新动向 ,进行了磷酸盐除铁法的试验研究 ,获得了较满意的结果。介绍了磷酸盐除铁新工艺的理论基础 ,着重阐述了其机理和研究成果。
Aiming at some defects and shortages existing in conventional deferrization processes,such as jarosite,goethite and spray processes,in zinc hydrometallurgy process and using new movements abroad for reference,the study on new technology for removing iron by phosphate has been carried out and satisfactory results have been achieved.In this paper,the theoretical deferrization principle of the new technology by phosphate describes emphatically the mechanism of removing iron and research achievements is presented.
