Conclusions
Some results from the mastery of the thermal hydrolysis section of the pilot plant using the HCl method are reported. The main characteristics typifying the operation of the atomizing reactor for the thermal hydrolysis of magnesium chloride and the absorption section for the regeneration of the HCl are considered. Evaluations of the corrosion resistance of the design materials and the protective coatings of individual parts, units, and elements of the pilot plant are given.
The data obtained during the run-in period indicate the suitability of the first Soviet-made plant for the chemical beneficiation of magnesite and the feasibility of using it in an appropriate modification as a low-tonnage plant for producing a beneficiation product with a mass fraction of MgO>98%. Moreover, the plant can be considered as the experimental base for improving the technology and equipment for the purpose of conversion to large industrial chemical beneficiation plants for magnesite. The beneficiation product is suitable for the production of periclase powders with a mass fraction of 98–99% of MgO destined for the production of refractories for heavy-duty use.
