Abstract: 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 comprises the steps of: - subjecting the residue to a flash or agitated bath fuming step, thereby producing an Fe bearing slag and Zn- and Pb-bearing fumes; and - extracting the Zn- and Pb-bearing fumes and valorising Zn and Pb; characterised in that CaO, SiO 2 and MgO are added as a flux before or during the fuming step so as to obtain a final slag composition with: formula (I) all concentrations being expressed in wt%. The invention also relates to a single-chamber reactor for Zn-fuming equipped with one or more submerged plasma torches as heat and gas sources.

Abstract: A method and a plant for treatment of fly ash are described, wherein heavy metals are separated and wherein there is formed a leaching resistant slag. The treatment takes place in a reactor (2) and the fly ash is introduced into an oxidizing gas stream which is heated to at least 2500 DEG C in a plasma generator (1). The fly ash melts and forms liquid drops of slag. A carbonaceous or hydrocarbonaceous material is added to the gas stream. This burns and supplies extra energy to the process. The ratio of oxygen and carbon is regulated in such a manner that the ratio CO2/CO + CO2 is kept within the limits 0.4 - 0.9. Heavy metals in the fly ash such as zinc and lead are thereby reduced and pass into the gas phase. The gas is discharged from the reactor (2), cooled and washed and metal oxides are separated. The gas will also contain chlorine and sulphur which are separated in a gas scrubber. The slag is collected in the bottom of the reactor (3) and can be continuously tapped via a slag lock (9). The slag's content of CaO and SiO2 can be regulated by the admixture of a slag-forming material with a high content of SiO2. A slag is thereby obtained with excellent leaching resistance.

Abstract translation: 描述了一种用于处理飞灰的方法和设备，其中分离重金属，并且其中形成耐浸出渣。 处理在反应器（2）中进行，并将飞灰引入到在等离子体发生器（1）中被加热至至少2500℃的氧化气流中。 飞灰熔化并形成液滴。 将碳质或烃类材料加入到气流中。 这会烧伤并为过程提供额外的能量。 调节氧气和碳的比例，使CO 2 / CO 2 CO 2的比例保持在0.4-0.9的范围内。 因此，飞灰中的重金属如锌和铅因而减少并进入气相。 气体从反应器（2）排出，冷却和洗涤，金属氧化物分离。 气体还将含有在气体洗涤器中分离的氯和硫。 炉渣收集在反应器（3）的底部，并可以通过炉渣锁（9）连续地攻丝。 炉渣中CaO和SiO2的含量可以通过成渣材料与高含量SiO2的混合来调节。 从而获得具有优异的耐浸出性的炉渣。
