Global Drivers for High Grade Concentrate | Magnetite Mines

Magnetite has low external fuel requirements during induration as it is exothermic, releasing latent energy in the form of heat as it oxidises. This quality reduces the production costs, increases productivity, improves competitiveness and leaves a smaller environmental footprint for steelmakers. Exothermic vs Endothermic
