Limestone was calcined in a rotary kiln fired with natural gas. The kiln was operated at steady state, producing 280 tonnes of dead-burned lime per day. The stones fed to the kiln analysed (wt \%): 96%CaCO3,2%SiO2,1%Fe2O3, and 1%H2O. Calculate: a) The feed rate of limestone and b) The chemical analysis of the lime made
