• Iron and Steel Slag Market Size, Share, Industry Forecast 2028

    Iron and steel slag, also referred to as ferrous slag, are created by adding calcareous (or dolomite), silica sand, and lime to blast furnaces to remove contaminants from iron ore, and other ferrous feed resources and to reduce the heat conditions of iron and steel processing. Iron and steel slag is a by-product in the method of steelmaking.
