Abstract
The effect of thermal destruction of coal on the parameters of reduction of iron oxides from concentrates has been experimentally studied with an STA 449C Jupiter differential scanning calorimeter equipped with a QMC 230 mass spectrometer. It has been found that thermal destruction increases the reduction rate and decreases the temperature of the beginning of the process because of an increase in the reduction potential of the gas phase and in the specific surface area of coal. The products of thermal destruction of coal hardly participate in the carburization of the reduction product.
