Fluorite is one of the common non-metallic minerals, the chemical formula is CaF 2.It is widely used in metallurgy, chemical engineering, ceramics, glass, casting and other industries. Common fluorite beneficiation methods mainly include manual selection, gravity separation and flotation, among which flotation is the most used. There are 8 main factors affecting the fluorite flotation effect.
