All lithium ore with industrial value can be enriched by flotation, especially the fine-grained disseminated lithium ore. Flotation is done in an alkaline environment, as it not only has a good flotation result but also protects the flotation machine and is easy to control. There are two flotation processes for lithium ore: positive flotation ...
Add strong alkali (such as sodium hydroxide or sodium carbonate) for flotation after the lithium ore is ground. After high-concentration, strong stirring, and multiple scrubbing in alkaline medium, oleic acid and its soaps are added as collectors to float lithium concentrate, leaving gangue minerals in the tank. This process does not require inhibitors.
