Sažetak
The article presents the results of studying the beginning, end and temperature range of softening of Kazakhstan manganese ores of the Bogach and Yesimzhal deposits. The experimental study was carried out using a softening unit on the Tamman furnace. The results obtained showed that the ore of the Yesimzhal Deposit has a low softening temperature compared to the ore of the Bogach Deposit, but the ore of the Bogach Deposit has the lowest softening temperature intervals. The dependence of the degree of softening of the investigated manganese ores on the temperature is established. The chemical composition was qualitatively evaluated, and the main phases in the samples of manganese ores were determined by x-ray phase studies.
