MIX MATERIAL FOR EXTRACTION OF LITHIUM FROM LITHIUM CONCENTRATES MIX Russian patent published in 2014 - IPC C22B26/12

Abstract RU 2531019 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy. The mix material for lithium extraction contains a mix of spodumene (SK) and lepidolite (LK) lithium concentrates and sodium carbonate. And the mix material contains sodium carbonate on the basis of obtaining of the mass ratio SiO₂/(Na₂O+K₂O+Li₂O), equal to 2.2÷2.3, and spodumene and lepidolite concentrates contains with the mass ratio SK/LK, equal to (1.0÷1.3):1.0, and mass ratio of oxides SiO₂/(Na₂O+K₂O+Li₂O), equal to 4.7÷4.8.

EFFECT: increase of level of lithium extraction is provided.
