Iron ore (Fe2O3) is refined to iron (and carbon monoxide) by reacting the iron ore together with coke (pure carbon, C) What mass of coke is required for every 1.000 kg iron ore refined?Steps please.Thanks.
The smelting reaction is Fe2O3 + 3C 2Fe + 3CO 2 mol of Fe2 requires 3 mol C 1 kg of Fe 17.91 mol and will require 3 / 2 x 17.91 26.86 mol of C or 322.6 g of carbon. Coke (as supplied to a Blast Furnace) is essentially fixed carbon, some ash and moisture and typically 82% fixed C, 13% ash and 5% moisture. Thus the coke equivalent of the above is 322.6 / 0.82 or 0.393 kg So to make 1.000 kg of Fe you need 0.393 kg of coke assuming a iron source of 100% haematite (Fe2O3)
