- Why does silica operate at highly temperaturearrow_forwardOne can view the blast furnace from a simple viewpoint as a process in which the principal reaction is: Fe2O3 + C → Fe + CO But some other undesirable side reactions occur, mainly Fe2O3 +C → FeO+CO After mixing 600 lb of carbon (coke) with 1.00 ton of pure iron oxide, Fe2O3, the process produces 1200 lb of pure iron, 183 lb of FeO and 85 lb of Fe2O3. Calculate the pounds of carbon used up and the pounds of CO produced per ton of Fe2O3 charged and the selectivity in this process (of Fe with respect to FeO).arrow_forwardTo determine the amount of magnetite.
