blast furnace makes pig iron containing 3.6% C, 1.4% Si and 95% Fe. The ore used contains 80% FE2O3, 12% SiO2 and 8% Al2O3. The coke analysis shows the presence of 10% SiO2 and 90% C. The flux used is pure CaCO3. The exit gases contain 28% CO and 14% CO2. The coke ratio is 1000 kg/t pig iron. Flux is 400 kg/t pig iron. Calculate per tonne of pig iron: (a) the weight of the slag made, (b) the weight of the ore used, (c) the composition of slag the air required at NTP.
