Abstract
A study of simultaneous effects of the major processing variables on the extent of reduction of a column of iron ore fines surrounded by coal fines in an externally heated shaft reactor is reported. The variables studied are ore particle size, coal particle size, coal/ore ratio, time, and temperature. Statistically planned series of isothermal experiments have been carried out to quantitatively assess the effects of each of these variables and of their interaction on the extent of reduction. Within the range of the variables studied, use o f computational methods to find the values of each of the variables to obtain the maximum extent of reduction have also been discussed.Keywords
