| Abstract Scope |
This project introduces a sustainable alternative to conventional high-carbon submerged arc furnace methods by converting under-utilized manganese ore fines and hazardous mill scale waste into value-added low-carbon ferro-manganese nuggets. Self-reducing composite pellets are produced by blending manganese ore fines, mill scale, and carbon-neutral biochar and classifying the dried pellets by density to ensure uniform internal porosity distribution. The experimental workflow integrates comprehensive material characterization (XRF, XRD, and wet chemical analysis), stoichiometric calculations, and FactSage thermodynamic modeling to optimize the muffle furnace heat treatment boundaries. Post-reduction analysis using XRD, SEM, and wet chemical analysis revealed that the actual pellet metallization reached 58.427 ± 2.668% metallic Fe, remarkably exceeding the 42% theoretical expectation. This high iron enrichment provides concrete physical proof of successful slag-metal separation and targeted ferromanganese nugget formation, validating an efficient pathway for emission-lean upgrading of secondary metallurgical by-products to ferromanganese. |
