摘要： 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, SiO2 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.

摘要： A process for batchwise working-up valuable metals containing recycling materials having a content of organic constituents so high that its use as smelting materials in conventional metal smelting processes is not suitably or even possible. The material is charged to a tiltable reactor rotatable along its own longitudinal axis having a common opening for charging and emptying. The material is heated to a temperature promoting the expulsion of organic constituents by pyrolys and/or combustion. The material consists at least to an essential part of such size fractions that admits a continuous charging during operation. The process is characterized in that said material during operation is charged continuously in an adjustable stream being controlled and/or adjusted by means of running measurements of different process variables so that the flow and composition of the combustible gas and the heat release is kept under control. A worked-up product substantially free from any organic substance is withdrawn from the reactor and is added to a conventional metal smelting process. The material is suitably supplied during operation by means of a charging equipment provided against or down through the single opening of the reactor by means of gravity and/or a pneumatic transport gas.

摘要： An apparatus and method for processing liquid slag and baghouse dust from a steelmaking furnace such as an EAF to recover valuable metals from the slag and dust includes a treatment vessel having a movable lower shell portion for receiving liquid slag and an upper shell portion that couples with the movable lower shell portion during heat activation of the treatment vessel. The slag is combined with silicon dioxide, a reducing agent, baghouse dust, and an inert gas before being heated to between approximately 1400°C and 3000°C. The heat treatment results in a molten reduced iron and manganese metallic material, a treated slag layer, and an off-gas containing lead, zinc, and carbon monoxide. The off-gas is combusted, cooled, and solidified, resulting in lead oxide and zinc oxide. The slag layer is tapped, cooled, and solidified. The metallic layer is tapped for recycle in the steel making process.
