摘要
Pyro-hydrometallurgical process for the recovery of zinc, lead and other value metals in form of oxides from iron- and steelmaking powders, in particular from EAF dusts. In comparison to other pyrometallurgical processes, the process according to the invention stands out by virtue of important process features which allow to prevent powder losses at the pyro-hydrometallurgical stage and to simplify and make more cost-effective the hydrometallurgical stage, as well as to increase its yield. The figure shows a block diagram for the carrying out of an embodiment of the process according to the invention.
