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

Samancor Chrome Mines Mining Technology

Samancor’s operations are centred on reserves held in the Bushveld layered intrusive complex, which contains approximately 70% of the world’s economic chrome ore reserves in the Lower Group (LG) 6 and Middle Group (MG) 1 seams. LG6 has a Cr2O3 content of 43-47% and a Cr:Fe ratio of 1.6:1, while MG1 averages 42% Cr2O3 Mhona, however, could not comment specifically about the Chinese chrome smelters in Gweru, saying he was not familiar with the issue.

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.
