Influence of the impurity concentrations of rocks in original magnesites on the quality of the raw materials and concentrates

Refractories Aims and scope

Conclusions

The maximum permitted total amount of impurity rocks of diabase and dolomite in unbeneficiated magnesite grade I, guaranteeing its possible use for the production of highly refractory articles and powders, in accordance with TI 200-0-45-82 equals, for TsMP-2 2.0%, and for TsMP-3 3.1%.

The calculation ratios of magnesite and impurity rocks in the original raw material enables us to assess the original raw material for determining the desirability of its beneficiation and planning the quality of the ores delivered to the various departments of the Combine in relation to the qualitative composition of the ore at the face.

To obtain magnesite concentrate suitable for making highly refractory articles and powders in accordance with TI 200-0-45-82, the mass proportion of CaO in the original raw material delivered for beneficiation should not exceed 5.5%, and the dolomite impurities 7.0%.
