Slag Recycling and Metal Recovery - MEKA

Slag recycling - recovery - Recovery Worldwide

1 Introduction2 Slag Recycling and The Circular Economy3 Global Market Data4 Trends in Slag Recycling5 ProspectsIron and steel slags are valuable raw materials that are obtained during the pig iron and crude steel production processes. Two main production methods are involved (Fig. 1). In the iron ore-based process, pig iron is produced from oxidic iron ores in a blast furnace.
