: The research aims to reveal the structure, phase, and elemental content of manganese ores
from deposits—Bogach (Karaganda region, Kazakhstan) and Zhaksy (Akmola region, Kazakhstan).
The samples were studied with scanning electron microscopy with energy dispersive analysis (SEMEDA), X-ray diffractometry (XRD), Infra-red spectroscopy (IRS). During the research, structural
peculiarities, elemental and phase content of the samples have been revealed. The mineral matter
of the Bogach deposit ore mainly consists of hollandite, cryptomelane, braunite, calcite, bixbyite,
quartz. The Zhaksy deposit ore includes quartz, hollandite, bixbyite, pyrolusite. Bogach ore includes
(wt.%) C(10.68), O(32.00), Mn(43.26), Ca(6.36), Si(3.51), Na(0.52), Al(1.13), Mg(0.69), K(1.85). The
elemental content of Mn in Zhaksy ore is two times lower. Zhaksy ore includes (wt.%) C(23.77),
O(32.1), Mn(21.81), Si(10.52), Al(5.13), K(1.21), Fe(5.47). The obtained data of the conducted spectral
analysis indicate that both samples represent a polymineral heterogeneous structure. Conducted
research allows to conclude, that by phase-elemental content the Bogach ore can be used for obtaining
trimanganese tetraoxide pigment similar to manganese ores from West Sumatera deposit (Indonesia)
by top-down method using grinding with a milling tool and high-temperature sintering.
