ABSTRACT
Reduction of iron oxide has been a subject of many studies because of its obvious importance in the iron and steel industry. This reaction, in one form or another, plays an important role in most of the commercial iron and steelmaking systems in use, and it also forms the basis of a number of alternative process developments which are on the verge of commercial exploitation. Nevertheless, the reduction of iron oxide-rich slags is now being seen in a new perspective with the emergence of Smelting Reduction (SR) processes. In bath smelting SR processes, for example, iron oxide and coal are charged into a liquid iron bath. Cracking of coal and reduction of iron oxide-rich slags constitute the major reactions, and because of these reactions, a large amount of carbon monoxide and hydrogen are generated and become primarily responsible for slag foaming.
