Abstract
A method of producing a metal matte from an unroasted high-gangue content ore which contains iron sulfides by using ferric oxide as a flux to react with the iron sulfides of the ore and provide the oxygen needed to both remove them from the matte and to produce additional ferrous oxide to slag the gangue thus reducing or eliminating the need for a separate converter step.
