    • The invention relates to a process for the separation and recovery of non-ferrous metals from zinc-bearing residues, in particular from residues produced by the zinc manufacturing industry. The process allows for the valorisation of metal values in a Zn-, Fe- and Pb-bearing residue, and comprises the steps of: -subjecting the residue to a direct reduction step, thereby producing a metallic Fe-bearing phase and Zn- and Pb-bearing first fumes; - extracting the Zn- and Pb-bearing first fumes and valorising Zn and Pb; - subjecting the metallic Fe-bearing phase to an oxidising smelting step, thereby producing an Fe-bearing slag and second metals-bearing fumes; - extracting the second metals-bearing fumes and valorising at least part of their metallic content. The main advantage of this process is that an environmentally acceptable output for Fe is obtained.
    • 本发明涉及从含锌残留物,特别是由锌制造业生产的残余物中分离和回收有色金属的方法。 该方法允许在含Zn,Fe和Pb的残留物中金属值的增值,并且包括以下步骤: - 将残余物进行直接还原步骤,由此产生金属Fe-相和Zn-和 含Pb的第一烟; - 提取含Zn和Pb的第一烟和钒和铅的增值; - 使金属含Fe相进行氧化冶炼步骤,从而产生含铁渣和第二含金属烟雾; - 提取第二个带有金属的烟雾和至少部分金属含量。 该方法的主要优点是获得了一种环境可接受的Fe产量。
