dc.description.abstractThe work highlights the study on chemical and phase composition of stripping waste and manganese ore tailings at Zhairem deposit. It was shown that the overburden rocks have a complex mineral composition and contain 14.6 wt. % manganese in (Mn2O3)3MnSiO3 in braunite form. Enrichment tailings are represented mainly by 76.4 wt. % calcite and contain 2.4 wt. % of braunite. On the basis of manganese ore concentration wastes in the temperature range of 200°C – 800°C, phosphate materials were synthesized due to an acid-thermal method. Alongside, their composition and aqueous solubility were studied as well. It was shown that the product synthesized at 200°C contains mainly acidic and medium diphosphates of calcium, silicon and manganese (III) monophosphate. The mentioned product has a high aqueous solubility of 92.4 %. Increasing the synthesis temperature to 400°C and 600°C grows the depth of phosphate anion dehydration process, and results in the formation of poorly soluble calcium polyphosphates Ca(PO3)2 and trivalent manganese Mn(PO3)3that partially turn into a glassy state at 800°C.
