Abstract

A method for producing a ferro-alloy, such as steel, in a metallurgical furnace and a reductant feed material for use in the method are disclosed. The method includes using a hydrocarbon polymer as a part of a reductant feed material and selecting a ratio of the hydrocarbon polymer addition and the other reductant addition to optimise operational indicators of the method. The reductant feed material includes a (i) a hydrocarbon polymer and (ii) another reductant.
