The project goal is to compare the reduction potential of two different coals in reduction of iron ore fines, by obtaining the energy of activation values required by the reduction reactions. The variables studied are time and temperature, coal/ore ratio, size of the iron ore fines and size of the coal fines. The reduction was done at three different fixed temperatures. The degree of reduction of fines was calculated at different time intervals, at fixed temperatures and variable parameters. The experiments were statistically designed such that the effect of each variable can be quantitatively assessed and compared. Then the observations were noted down and graphs were plotted between degree of reduction and time; then the appropriate rate law, was chose...
