ADVANTAGES of Limestone of Khudolaz deposit

Limestone of Khudolaz deposit is successfully used in chemical, metallurgical and glass industries due to its chemical composition: high content of CaO (up to 56%), low content of insoluble residues (less than 1% SiO2, etc.), almost complete absence of iron, sulfur and phosphorus.

Limestone mainly consists of calcium carbonate, from which lime of high quality is obtained by observing all necessary norms and requirements.

Environmental safety, absence of harmful impurities, specific activity of radionuclides is 5 times lower than the minimum permissible — our materials are used in the manufacture of food additives and feeds for animals and birds.
