© 2022, The Minerals, Metals & Materials Society.In this study, the reducing smelting of chromite concentrates by EAF-assisted metallothermic method was investigated. The effect of AlPowder and AlDross addition amount, time, and the ratio of flux addition on the produced metal and slag compositions and metal recovery were investigated. It was seen that ferrochrome can be produced from fine-grained chromite concentrate by this method. As a result of EAF-assisted semi-pilot metallothermic smelting, the highest chromium content in produced alloys was 59.5 wt. %, while the highest chromium recovery from chromite concentrate to alloys was 76.7 wt. % in these experiments.
