While the primary ore for iron and steel production is based on oxide minerals, which can be used as a feedstock for electrolysis and production of iron metal and oxygen gas, iron sulfide as a feedstock offers an opportunity for electrolysis in molten sulfides. Using sulfur- and sulfide-based chemistry for the preparation of iron sulfide and for electrolysis is promising for the mitigation of GHG emissions, yet, to date, the features of a molten sulfide electrolysis process for iron have not been reported. Herein, we present some of the key background work that supports the features of iron production by molten sulfide electrolysis.
