Slag-What is it Good for? U.S. Geological Survey Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded. However, slag could be used to treat acid soils or acid mine drainage. Doing so would both offset the cost of restoring abandoned mine areas, as well as decrease steel manufacturers current waste footprint. Melting Iron Without Forming Slag - Foundry Management TechnologyWhen iron oxide is present in surface slag, free-oxygen atoms will be present in the molten iron bath. The equilibrium chemical equation - FeO = Fe O - is the supply mechanism for free-oxygen atoms. Currently, all the iron that is melted contains some volume of free oxygen unless it has been specifically deoxidized.
