铁矾渣综合利用技术进展

Progress of Comprehensive Utilization Technology of Jarosite

  • 摘要: 在有色冶炼的沉铁过程中会产生大量的铁矾渣,直接堆存处理不仅会对环境造成危害,也是一种资源的浪费。目前国内外对于铁矾渣的处理处置方法,主要是通过火法工艺、湿法工艺、选矿工艺及联合工艺等回收Zn、Pb、Ag、In、Fe等有价金属,其次利用铁矾渣制作功能材料和建筑材料,以及最终无害化固化处置。认为在铁矾渣处置过程中减少二氧化硫和废水排放,避免重金属污染,实现主要有价金属回收的同时减少尾渣数量是今后研究的热点。

     

    Abstract: In the deironing process of non-ferrous metallurgy, a large amount of jarosite residue has been produced, which is not only harmful to the environment, but also a waste of resources if directly deposited. At present, the main treatment and disposal of jarosite residues, include the pyrometallurgical process, hydrometallurgy process, beneficiation process and the joint process for the recovery of valuable metals such as Zn、Pb、Ag、In、Fe, or using jarosite residues to make functional materials and building materials, and the final solidification treatment. It is considered that reducing the discharge of sulfur dioxide, wastewater and tailings, and avoiding the heavy metal pollution while achieving and the recovery of valuable metals are the focus of research in the future.
