Spodumene and processing methods are hand-selected method turquoise and flotation, the flotation method is flotation method and reverse flotation, flotation is frequently used, its essence is finely ground ore, flotation lithium Pyroxene, in the alkaline slurry of sodium hydroxide or sodium carbonate, after high concentration, strong stirring, multiple washing and de-sludge, adding fatty acid (such as oleic acid) or its soap as a collector to directly float lithium Pyroxene; after three selections, a spodumene concentrate with a grade greater than 5% LiO2 and a recovery of 70% to 75% can be obtained. A mine ore in Xinjiang, China contains 1.3% LiO2. After normal temperature flotation, the grade of spodumene concentrate is 4% to 5%, and the recovery rate is 85% to 90%.
The reverse flotation process of spodumene is to inhibit the spodumene in a lime-adjusted alkaline medium using dextrin, starch, etc., and use a cationic collector (such as the acetate alcohol of dextrin) to float the silicate. A gangue mineral, the product in the tank is a spodumene concentrate, and if necessary, an HF resinate foaming agent is used to further extract iron minerals.
(1) The hand selection method is selected according to the appearance characteristics (color, gloss, and crystal form).
(2) Flotation method
1 acid method (sub-mixing method and priority method) The acid mixing flotation process uses amine acetate to float out mica , then hydrofluoric acid activates beryl and feldspar , and the mixed concentrate is washed (added chlorine) Calcium acid) and drug removal, flotation of beryl with petroleum sulfonate. The acid process priority process uses sulfuric acid, aluminum sulfate and the like to adjust the slurry, and the cationic collector is used to remove the mica, then the ore washing, concentration, and hydrofluoric acid treatment, and the fatty acid (such as oleic acid) and neutral oil are used in the soda medium. Class of medicine flotation beryl.
2 alkaline alkali flotation process is to pre-treat the ore with alkali (sodium hydroxide-sodium sulfide-sodium carbonate or sodium hydroxide-sodium carbonate) before grinding or flotation, and wash and de-sludge, or Without this process, a (hot) fatty acid collector, emulsifier and foaming agent flotation beryl are added.
