Popis:	Effect of the concentration of sulfuric acid used for beryl sulfatization, degree of beryl grinding, temperature and duration of beryl sulfatization, and other technological parameters of sulfuric acid decomposition on the extent of beryl recovery was studied. The results obtained made it possible to suggest a method for preparation of beryl concentrates for sulfatization. The method is based on a mechanochemical activation of this kind of raw materials and can serve as an alternative to the conventionally employed beryl activation techniques.
