The high yield in the Consteel process benefits from its design. Fluxes, chemical energy inputs and carbon inputs – whether in the metallic charge, through injection into the EAF or other – must be properly balanced to maximize yield. Consteel operates without any highly oxidizing burner flame and the constant flat bath in the EAF helps keep the FeO oxidizing/reducing reactions within the slag itself, so that the proper carbon balancing in the slag can lead to iron recovery and maximise metallic yield.
