blast furnace charge consists of magnetite

  • Global Drivers for High Grade Concentrate | Magnetite Mines

    Most of the iron and steel industry’s emissions occur during production of iron in the blast furnace, where coal and coke are used as fuel and as a reducing agent. Magnetite has low external fuel requirements during induration as it is exothermic, releasing latent energy in the form of heat as it oxidises.
