Description

Conditions of actually full decomposition of loparite concentrate at a temperature of 95 Deg C by hydrochloric acid, its concentration 37 % at S : L = 1 : 4, for 6 h were ascertained for developing hydrochloric acid technology of loparite. Extraction separation of the sum of titanium (IV), niobium (V) and tantalum (V) using octanol was carried out under laboratory conditions in a continuous mode. The process of low-soluble Cs2TiCl6 precipitation from back-extraction solutions was tested for separation of titanium (IV) and niobium (V)

Abstract (Russian)

С целью разработки солянокислотной технологии лопарита определены условия практически полного разложения лопаритового концентрата при температуре 95 град С соляной кислотой концентрацией 37 % при Т : Ж = 1 : 4 в течение 6 ч. В лабораторном масштабе в непрерывном режиме проведено экстракционное выделение суммы титана (IV), ниобия (V) и тантала (V) с использованием октанола. Для разделения титана (IV) и ниобия (V) опробован процесс осаждения малорастворимого Cs2TiCl6 из реэкстрактов
