How much pig iron can be obtained from 1 ton of iron ore (Fe2O3), which has 0.8% impurities, if the iron content in the resulting pig iron is 92%?

Decision:
Fе2O3 + ЗН2 = 2Fе + ЗН2O
m (Fe2O3) = 1000-1000 * 0.008 = 992g
2v (Fe2O3) = v (Fe) = 992/160 * 2 = 12.4 mol
m (cast iron) = 12.4 * 56 / 0.92 = 754.8g
Answer: 754.8g
