2015-9-1  Steel production occurs primarily through integrated or semi-integrated routes. In the former route, the reduction of the raw material (iron ore, sinter and/or pellets; mineral coal or charcoal; and fluxing agents) in the blast furnace generates pig iron, which is then refined to produce steel, while in the latter route, steel is directly produced in electric arc furnaces (Fruehan, 1998).

How to Control Pollution in Iron and Steel Industry?
