Abstract
The present disclosure relates, according to some embodiments to a method for steel production, the method comprising forming a hydrogen and a carbon from a natural gas using thermal plasma electrolysis; reducing iron ore fines with the H2 to form an iron briquette; melting the briquette iron from the furnace to form a melted iron and melted non-metallic slag; separating the non-metallic slag from the melted iron in the furnace; combining the carbon and the melted iron in a furnace to form a carbon black and iron mixture; and alloying the melted iron with the carbon black to form a steel.
