Abstract

An alternative ironmaking process for simultaneously producing a highly metalized iron/steel product, coke from coal, an iron/steel product from an iron rich feedstock, and, optionally, energy using heat recovery. The simultaneous process is performed in the environment of a non-recovery or heat recovery coke oven. The iron rich feedstock is layered on top of a coal bed. The iron rich feedstock and coal bed are heated in the presence of a reducing gas to reduce the iron oxides of the iron rich feedstock into the iron/steel product and to devolatilize the coal into coke. After quenching the iron/steel product and coke, the iron/steel product is separated from the coke.
