A solid ore containing 82 wt% FeS2 and 18 wt% inert is fed to a furnace. Dryair is fed in 40% excess of the amount theoretically required to oxidize all ofthe sulfur in the ore to SO3 . A pyrite conversion of 85% is obtained, with 40%of FeS2 converted to form sulfur dioxide and the rest forming sulfur trioxide.Two streams leave the roaster: a gas stream containing SO3 , SO2 , O2 , and N2, and a solid stream containing unconverted pyrite, ferric oxide (Fe2 O3 ), andinert. Using 100 kg/min of ore as a basis, calculate the rate of Fe2O3 production(kg/min) in the outlet solid stream, and the total molar flow and composition ofthe outlet gas stream. The following reactions take place in the furnace:FeS2 ( s ) + 15/2 O2 ( g ) → Fe2 O3 ( s ) + 4 SO3 ( g )2FeS2 ( s ) + 11/2 O2 ( g ) → Fe2 O3 ( s ) + 4 SO3 ( g
