Abstract

A method of producing ferrous metal strip from iron ore comprising the steps of beneficiating the ore into a concentrate powder form, forming the powdered ore into pellets, passing the ore pellets through a furnace in the presence of a reducing gas acting as the sole or primary reductant and compacting the reduced pellets in the nip of a rolling mill to produce a strip of ferrous metal. The reduced pellets may pass to the rolling mill at the furnace temperature, or at a lower temperature followed by a sintering step. The step may be subsequently hot-rolled.
