A fundamental study on some aspects of nonisothermal reduction of iron ore by both solid and gaseous reductions has been carried out. The aim is two fold:
(a) to develop appropriate mathematical procedure for the analyses of nonisothermal kinetic data and evaluation of kinetic parameters and
(b) to develop a theory for kinetic studies of reduction under fluctuating but measured temperature.
These theories have been tested against actual experimental results on reduction of iron ore by solid and gaseous reductants. A mathematical procedure conveniently amenable to computation is described which can be used to predict the course of reaction under fluctuating temperature conditions.
