A manganese ore with a composition given below is reduced with carbon in order to produce an alloy phase consisting of Fe,C and Mn,C only. An amount of Cao which is equal to the amount of Sio present in the ore is added to the charge as a fluxing agent. A part of manganese present in the ore is lost into the slag in the form of MnO which forms 10% of the slag phase. In order to produce 100 kg of alloy phase (Fe,C + Mn,C), calculate: i. Amount of ore used ii. Amount of carbon used iii. Composition of the alloy produced iv. Amount and composition of the slag produced Composition of manganese ore: Mno,: 50%, Fe,03: 10%, FeO: 20%, SiO,: 10%, MgO: 5%, A1,0g: 5% 21
