I need help with this problem, so far i only be capable to calculate de O2 and N2
A mineral of a process contains contains 90% FeS2 and 10% inerts by weight. This material it is calcined with 25% excess air, according to the reaction:
FeS2 + 02 ► Fe203 + S02
The solid mixture leaves the calciner with 13% inerts by weight and the rest FeS2 and Fe203
a) Calculate the weight of solids leaving the calciner.
b) Determine the% conversion based on FeS2 •
c) Calculate the Orsat analysis of the gases produced.
