Dolomite of the Skursk deposits

Conclusions

Analyses were carried out of samples of dolomite from the Skursk deposits in the form of white, pale-gray, and gray rock of fine-grained, medium-grained, and consertal structures.

Dolomite samples Nos. 1, 2, 5, 7, and 8 and T-1 conform to the specifications of raw dolomite intended for the production of tar-bonded dolomite refractories, and samples Nos. 3, 4, and 6 to those of the State Standard for raw metallurgical dolomite.

The dolomite is not readily sintered. It can be sintered to apparent density 3 g/cm³ and over by firing the material in granular form, grain size 5–15 mm, at 1780°C without added scale and at 1700°C with added scale, or by firing it in briquets of fine-ground or caustic dolomite at 1750°C.
