Abstract

In this research were studied the chemical and mineral compositions of some iron ores in Mongolian the western region. Also the study investigated the effect of calcium fluoride on decomposition temperatures of calcite in the raw mix for obtaining cement clinker.

The chemical investigation result showed that iron oxide (Fe2O3) content in the western Mongolian iron ores represents in Uvgondatsan (Khovd) – 87.23%, Suul Khar (Khovd) – 85.00% and Kharganat (Uvs) – 89.29%, respectively. Iron ores of Kharganat and Uvgundatsan are mostly contained magnetite (Fe3O4) while iron ore of Suul Khar is mostly contained hematite (Fe2O3).

The decomposition temperature of calcite (CaCO3) was reduced by 5°C, 10°C, and 15°C when calcium fluoride (CaF2) in the raw mix for obtaining cement clinker that consists of Shokhoit limestone, Shal clay and Kharganat iron ore was added up 0.5%, 1.0% and 1.5%.
