Description

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

Abstract (Russian)

Изучено влияние концентрации серной кислоты, используемой для сульфатизации берилла, степени измельчения берилла, температуры, продолжительности процесса его сульфатизации и других технологических параметров сернокислотного вскрытия на полноту извлечения бериллия. По результатам выполненной работы предложен метод подготовки берилловых концентратов к сульфатизации, основанный на механохимической активации данного вида сырья как альтернативы традиционно применяемым методам активации берилла
