Abstract

Based on the chemical composition of the manganese mineral, aluminum shaving and laminated rolled scale, a strategy is proposed to simultaneously produce ferromanganese and galaxite (abrasive material) through the application of aluminathermic reduction. The feasibility analysis of the aluminathermic process, bypassing the roasting stage of the pyrolusitic mineral, is carried out by assessing the enthalpies of the reaction of the pyrometallurgical mixtures. The feasibility evaluation of the technological process is completed both at lab scale and experimental pilot plant. Alloys for industrial use with over 60% manganese and less than 0,1% carbon were obtained in both cases. The chemical characterization of the slag will ensure that it can be used as abrasive material.
