Hot Slag Processing Aiming for Efficient Metal, Mineral and Energy Recovery - a Swerea MEFOS Perspective
The metallurgical industry generates every year huge amounts of slag.The annual amount of generated steelmaking slags alone is more than 100 million tons.The steel slag is normally used as construction materials,for instance,for road and river bank construction.Fully utilization of this huge amount of byproduct is limited by its leaching and volume stability properties.In addition to the useful minerals in the slag,there is also a considerable amount of feasible heat lost in the hot slag.Swerea MEFOS have been involved in a number of hot slag processing projects in the past 20 years.These projects included slag stabilization to improve the physical and leaching properties,slag reduction for metal recovery,dry slag granulation for heat recovery and for reduced leaching of heavy metals,etc.This paper will highlight some of the projects with focus on the wellknown IPBM and VILD projects.The extensive pilot experiences of Swerea MEFOS have shown that there is a wide range of options for economic and ecological recovery of metals,minerals and energy from hot metallurgical slag.
