Abstract

The slag-foaming phenomenon is observed in many pyrometallurgical processes such as basic oxygen steelmaking, pretreatment of molten pig iron and bath smelting of iron or chrome ore. The current state of understanding of this phenomenon is reviewed and particular attention is paid to its surface chemical view.
