— During the BOS process a proportion of the molten iron cannot be recovered so elemental iron is often observed in the slag (Yildirim and Prezzi, 2011). Slags can be classified into three different categories: ferrous slag (contains iron), non-ferrous slag and incineration slag.
Chemically, the slag layer consists primarily of oxides of calcium, iron, silicon, phosphorus, sulfur, aluminum, magnesium, and manganese in complexes of calcium silicates, aluminosilicates and aluminoferrite. The slag is typically removed by tipping the furnace backwards and pouring the molten slag out through a slag door1, at which point the
