The interaction between coal char and mixtures of pyrite, quartz, almina and kaolinite heating up to 1600℃ under Ar flow were investigated by thermogravimetric analysis combined with off-gas analysis. The chemical compounds of products obtained were identified by X-ray diffraction analysis. Pyrite reacted with other minerals in the presence of carbonaceous materials. Pyrite influenced the reaction of char and alumina above 1500℃. with the evolution of CO and the weight loss. Pyrite also influenced the reactions of char-quartz and char-kaolinite. As the result. those reaction temperatures decreased by 100-200℃.
