In the course of continuation of scientific research in the development of Kazakhstani technology for the production of trimanganese tetraoxide pigment, there have been proposed new methods of analysis which make it possible to investigate new nanostructural materials sourced from local deposits. The results obtained are of practical importance and serve as the foundation for developing new technologically advanced domestic production of a competitive product that is in demand both on the national and international markets. The available methods are not able to highlight the particularity and diversity of Kazakhstani manganese ores due to the uneven distribution of manganese minerals and host (waste) rock, the quantitative ratio of rock-forming components and their variation instability. Methods of energy-dispersive analysis of manganese ores from Kazakhstani Zhaksylyk and Bogach deposits have been put forward, electronic micrographs, spectrograms of samples, diagrams of normalized distribution of elements on the surface of samples have been obtained and a comparative analysis with raw analogue samples of some foreign manufacturers has been performed.

The article investigates the effect of the sintering temperature on the crystal structure and elemental composition of manganese ores from the Bogach and Zhaksylyk deposits (central Kazakhstan) by X-ray phase (XRD) and energy-dispersive X-ray fluorescence (EDX) analyzes. The results obtained are of practical importance and are relevant for the development of technologies for obtaining new phases of manganese minerals at a given temperature. There was used a temperature range of 600 ° C, 800 ° C, and 1000 ° C for the sintering process. As a result of the study, it was found that when the sintering temperature changes, the processes of phase transitions occur with the formation of stable thermostable phases, particularly, hausmanite and bixbyite. At the same time, the elemental composition remains practically did not change. For a sample from the Zhaksylyk deposit, an increase in temperature increases the homogeneity of the structure, which is expressed in an increase in the uniformity of the elemental composition after sintering at temperatures above 800 ° C.
