The Transformation of Ferrochromium Smelting Technologies
2AvestaPolarit Chrome Oy, FIN-95400 Tornio, Finland. E-mail: Matti.Honkaniemi@avestapolarit ABSTRACT In the latter part of the 1980’s Outokumpu Chrome in Tornio, Finland, was in a situation when its twenty-year-old ferrochrome plant was becoming inefficient to sustain economically sound production. TheAverage carbon costs from 2015–2020 in the GCC was $177 /t for that period. In 2021 and 2022, carbon costs were $83 /t and $177 /t higher, respectively than that average. In the world ex. China, CRU is only forecasting an increase in primary production of 1.3% in 2023, and any further weakening in LME prices could see the Aluminium smelters stung by the escalating costs of carbon

Economic modelling of a ferrochrome furnace SciELO
The production cost therefore shows a 2 per cent sensitivity to variations in the electrical inputs, which could account for the discrepancy in the predicted cost distribution. Conclusion Through the use of material and energy balances, a robust model was developed to predict the influence of numerous process variables on the profitability of a ferrochrome the cost-effectiveness of the specific process route. A good example of process optimization is the semi-empirical model developed by Broekman and Ford1, which incorporated the ore supply, smelting operations, as well as the markets to predict and improve the overall cost-effectiveness of the process.
