N2 - In this study, reduction behaviours of Turkish chromite concentrate (48 % Cr 2O 3, 13.30 % FeO, 18.33 % MgO, 12.37 % Al 2O 3, 5.76 % SiO 2) and nickel oxide by Fe-C alloy in graphite crucible were investigated. In the first stage of experiments, steel scraps were melted in graphite crucibles and were saturated with carbon at 1600 °C and 30 min. In the second stage, mixtures of different amount of chromite concentrate, nickel oxide and flux additives (CaO, SiO 2 and CaF 2) were charged into the graphite crucible containing the Fe-C alloy and heated to 1600 °C for different reduction times (0-180 min) under argon gas. The highest Cr and Ni contents in alloys were found as 11.41 and 14.37 % and the highest Cr and Ni recoveries were found as 88 and 94 %, respectively at 180 min.
