Answer to Question #285374 in Material Science Engineering for sara

Question

1 ton Zinc concentrate which is include 60% ZnS, 33%Fe₂O₃, 7%SiO₂. 20% Ore Charging Mass Weight Coal used for Calcination Process. Coal is include 72 % C, 6%H₂, 10%Sulphur and 12% ash. All volatile gasses are throw away gasses out chimney, and ash from coal do not join Zinc concentrate. Ore body concentrate 3% ZnS didn’t effect from Calcination. Oxidation Products are ZnO, Fe₂O₃ and SiO₂. Used air was applicated 50% added air from required. Please calculate air amount by volume, and chimney gasses by volume and find percentage chimney(stack) gasses.

(Zn:65, Fe:56, Ca:40, S:32, O: 16, Si:28, C:12)
