manganese froth flotation
Direct Recycling of Blended Cathode Materials by Froth Flotation
Herein, a froth flotation process is developed to separate pristine lithium nickel–manganese–cobalt oxide (LiNi 0.333 Mn 0.333 Co 0.333 O 2, NMC111) and lithium manganese oxide (LMO) materials. The flotation results show that with multiple stages of the separation processes, a satisfactory separation is achieved with 95% grade or above …

Effect of Sodium Oleate Concentration Variations on Froth Flotation …
Each type of a manganese deposit is a problem by itself in the matter of selection of a proper method of concentration, depending on the manganese minerals and their gangue constituents. Hence, this work studied the effect of sodium oleate concentration variation on the froth flotation of manganese ore obtained from Madaka, Niger State, Nigeria.
