Corex® - Cost-efficient and environmentally friendly ironmaking
Corex is an industrially and commercially proven smelting-reduction process – unique to Primetals Technologies. Corex enables the cost-efficient and environmentally friendly production of hot metal from iron ore and coal.
In the Corex process, all metallurgical work is carried out in two separate process reactors – the reduction shaft and the melter gasifier. Since coking and sintering plants are not required for the Corex process, substantial cost savings of up to 20% can be achieved in the production of hot metal, of a grade similar to that of the blast furnace. Regarding environmental concerns, Corex plant emissions contain only insignificant amounts of NOx, SO2, dust, phenols, sulfides and, ammonia. Emission values are already far below the maximum values allowed by future European standards. Furthermore, waste-water emissions from the Corex process are far lower than those in the conventional blast-furnace route.
