1. Influence of alumina on the zinc slag fuming processes : an experimental study on physical properties and leaching behaviour of the generated fayalite-type slag
Abstract : Recycling of secondary raw materials by non-ferrous metal producers is steadily increasing. These materials inevitably introduce various impurities to the production furnaces, which can change the chemical composition, and thereafter, the physical and chemical properties of the products and by-products of the operation.

2. Alternative Reducing Agents in Metallurgical Processes : Potential of shredder residue material as reductant in zinc fuming process
Abstract : .... READ MORE

3. Leaching behaviour of rock materials and a comparison with slag used in road construction
Abstract : Leaching characteristics are used for the evaluation of secondary materials used in road construction. In order to form a basis for comparison of the leachability, Swedish rock material have been investigated using the availability test NT ENVIR 003. READ MORE

4. Alternative reducing agents in metallurgical processes : Experimental study of thermal characterization of shredder residue material
Abstract : Coal used in metallurgical processes can participate in reduction reactions to produce metals and alloys from oxides. Base metals production leads to generation of slag, which contains valuable metals that can be recovered and recycled. There are several options to treat the slag, depending on the metal content in the slag. READ MORE

5. Slag Cleaning of a Reduced Iron Silicate Slag by Settling : Influence of Process Parameters and Slag Modification on Copper Content
Abstract : During the pyrometallurgical extraction of copper, a significant part of the copper is lost with discard slag, which decreases profits, overall copper recovery, and efficiency of raw material usage. Smelting furnace slag usually has a copper content that is close to or higher than that of copper ores. READ MORE
