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.
