| Abstract Scope |
Electrolytic reduction of hematite ore or waste bauxite tailings (red mud) has the potential to become a low-emission alternative to traditional blast furnace and direct reduction processing techniques for production of iron. Use of electrolytic reduction in these contexts will allow for valorization of toxic red mud waste. This study involves a techno-economic analysis of two electrowinning technologies and a CO2 emissions analysis of the two processes under study against incumbent and other novel iron production processes. Monte Carlo simulations were performed to account for uncertainties surrounding variable feedstock composition and process parameters. Under these conditions, the more favorable electrowinning process results in emissions significantly undercutting current carbothermic processes, and comparable to other novel iron production processes such as HYBRIT and molten salt electrolysis. |
