Froth flotation of lithium micas – A review

Abstract. Flotation of lithium micas and especially lepidolite is becoming a matter of increasing interest, as a result of the increased demand in lithium for the battery and other sectors of modern technology. Gangue minerals of lithium-mica deposits behave similarly during flotation, resulting in a difficult separation contrast.
