The Specific Composition of Magnesites of Provenance from The Satkinskoe Deposit. Carbonaceous Chlorite Matter

A polymineral component of the magnesite ore of provenance from the Satkinskoe deposit — the so-called carbon-containing matter — is analyzed for composition using advanced techniques. The component has a complex composition, with the prevalence of a magnesian ferrous aluminosilicate, chlorite, in it and, for that reason, may conventionally be termed a carbonaceous chlorite matter (CCM). The CCM, when heat-treated, yield compounds that lower the quality of the final product, which makes it necessary to develop a beneficiation technology for removing CCM from the Satkinskoe magnesite ore. Results of the present study can be used to develop new technologies for recovery and beneficiation of magnesite and its processing into refractory materials.
