Dependence of the thermal transformations in the fines of the chromium ore of the Donskoy Ore Mining and Processing Plant on the addition of silicate and aluminosilicate fluxes

Abstract

Differential thermal analysis is applied to study chromium ore, aluminosilicate fluxes, and mixtures of these materials. The dependence of the thermal transformations in the fines of the ore from the Donskoy Ore Mining and Processing Plant on the content and type of added fluxes is estimated. An analysis of the experimental results is supplemented with X-ray diffraction analysis of the sinters of chromium ore with a high flux (clay, microsilica) content (up to 10%), which corresponds to the end of softening of the mixtures.
