Steel slag can also be produced by smelting iron ore in a basic oxygen furnace. According to methods for cooling molten steel slag, steel slag is classified into five types: natural aircooling steel slag, waterspray steel slag, waterquenching steel slag, airquenching steel slag, and shallow box chilling steel slag .
The smelting of copper, lead and bauxite in nonferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores, and separates them as ironsilicatebased slags. Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium ...

Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina.
Converter slag is the oxidized material that is generated when lime and other auxiliary materials are added and oxygen is blown onto the pig iron in order to remove carbon, phosphorous, sulfur, and other components from the pig iron and refine it to produce strong steel. The other type of steelmaking slag, electric arc furnace slag, is ...
Basic Oxygen Furnace Steel Slag (BOF or Steel Furnace Slag) This slag Is formed when molten Iron, scrap metals and various fluxes, such as lime, are oxidized by injecting large amounts of pure oxygen into the molten iron mix to create molten steel and molten slag. Slow cooling of the molten slag produces a dense rock material. Principal uses ...
