One feature of the HCl treatment of magnesite is the possibility of using the main mass of HCl in a closed cycle. Regeneration of the HCl takes place during the thermal hydrolysis of the purified solution of magnesium chloride. In accordance with the plan drawn up by the Eastern Institute of Refractories and the Ukranian Institute of Chemistry, a pilot plant has been built at the Magnesite Combine; this has been mastered and is used for the hydrochloric acid treatment of magnesite; the annual productivity of the equipment is 400 tons. Some features of the process of dissolution of natural and caustic magnesite in HCL and the sintering of the beneficiated product have been considered elsewhere. This paper pays particular attention to the apparatus-process character and considers in more detail the hydrolysis of magnesium chloride.
