roasting of iron ore for ugradation

A sustainable reduction roasting technology to upgrade
2021-2-15 · Reduction roasting of manganese ores is a known process; however, it is not yet commercialized mainly due to various techno-economic issues. The current research work presents results of a large-scale plant trial performed at a commercial Direct Reduced Iron making plant to upgrade low-grade ferruginous manganese ores (Mn: 25–32%, Mn/Fe: ∼1).
