MIXTURE FOR PRODUCING BERYLLIUM SULPHATE FROM MIXTURE OF BERYLLIUM CONCENTRATES Russian patent published in 2015 - IPC C01F1/00

Abstract RU 2561402 C2

FIELD: chemistry.

SUBSTANCE: invention relates to processing beryllium-containing ore concentrates to obtain beryllium sulphate. The mixture is prepared to obtain weight ratio of SiO₂/CaO in the mixture of concentrates of 2.25-2.45, and sodium carbonate is added to obtain weight ratio of SiO₂/(CaO+Na₂O) in the mixture of 1.45-1.65.

EFFECT: mixture of bertrandite-phenacite-fluorite beryllium concentrates and sodium carbonate expands the raw material base for beryllium hydrometallurgy and provides high degree of extraction of beryllium during processing.
