The Corex tower stands 108.6 meters (356 feet) high and includes the reduction shaft and the melter-gasifier where all of the process functions of reduction, gasification and melting are carried out. Indigenous Thabazimbi lump ore is normally charged into the reduction shaft where it is reduced to direct reduced iron (DRI) with an average metallization degree of 93% by means of reduction gas in counterflow. Test campaigns have also demonstrated the suitability and feasibility of charging South African Sishen lump ore, Brazilian pellets and sinter from Newcastle works into the process for the production of high quality hot metal. The Corex process is more flexible compared to a blast furnace in that the burden composition charged to the melter-gasifier can be changed rapidly. This is because the coal and reduced iron is charged separately into the melting zone. A mixture of non-coking local coals are used as the source of energy for melting and as the reducing agent for the Corex reduction shaft.
