1. Settling Mechanisms of Valuable Metal Droplets in Iron Silicate Slag
Abstract : A significant source of copper losses from pyrometallurgical copper extraction is attributed to dissolved and entrained copper in discarded slag. Entrained copper can be recovered via pyrometallurgical slag cleaning in a settling furnace where the droplets settle under gravity. READ MORE

2. Preparation and characterisation of refractory whiskers and selected alumina composites
Abstract : A whisker is a common name of single crystalline inorganic fibre of small dimensions, typically 0.5-1 μm in diameter and 20-50 μm in length. Whiskers are mainly used as reinforcement of ceramics. This work describes the synthesis and characterisation of new whisker types. READ MORE

3. Study on the dissolution of lime and dolomite in converter slag
Abstract : In the present study, the dissolution mechanism and rate of lime, limestone and dolomite in converter slag was studied. Lime dissolution in stagnant slag was studied first and dissolution of lime, limestone and dolomite under forced convection were carried out by new experimental setup. READ MORE

4. Energy and environmental optimization of some aspects of EAF practice with novel process solutions
Abstract : The objective of the present thesis is to optimize the electric arc furnace (EAF) practice from an environmental view point. Two aspects that meet the requirements of the secondary steelmaking industries today, viz. READ MORE

5. A Study on the Influence of Steel, Slag or Gas on Refractory Reactions
Abstract : During the production of steel the oxide inclusion content partly depends on the reaction of the melt with the furnace lining, the ladle lining and the pouring system. The refractory material may be eroded by the molten steel and slag as well as corroded through chemical reactions with the slag and molten steel and the deoxidation products. READ MORE
