Abstract

The crushing and grinding of samples, as well as the reduction of ground ore in a hydrogen environment, were carried out. X-ray spectral analysis showed that the ore contains 4 main elements and meets the requirements of GOST for the content of harmful impurities. After the reduction of the ore, the oxygen content decreased by 3%, and the iron content increased with an increase in the particle size class. Oxidation of ore material increases with decreasing particle size.
