The main methods used in lithium ore separation include flotation, magnetic separation, dense medium method, combined mineral processing method, etc. Among them, flotation is one of the more widely used beneficiation methods. When flotation lithium ore, the choice of collector for lithium ore is the key to affect the flotation index of lithium ore.
