The most typical process is to use hydrofluoric acid as the activator, and use an amine cationic collector for flotation under strong acidity (pH=2～3). Flotation methods can be divided into three types: The first is the method with fluorine and acid. This method is widely used because of its good flotation effect, easy control and stable index.
