Here Are All Flotation Separation Processes For Different

Feb 04, 2021 Fluorite is an important non-metallic mineral resource and the main source of fluorine in the industry. There are three kinds of processing processes of fluorite hand separation, gravity separation and flotation separation. Among them, hand separation and gravity separation are mostly used as auxiliary separation and pre-separation, while flotation separation is the main method.
