Summary of Fluorite Ore Flotation Process

2.1 Quartz type fluorite ore. The separation of quartz and fluorite achieved by grinding, it is an important factor affecting the flotation of quartz-type fluorite. The ground ore of a coarse size indicates that may have many associated fluorite ore lumps, these lumps may increase the silica content, decrease the flotation effect.

The Mississippi Valley-type fluorite ore at Jebel Stah (Zaghouan

The ore-forming fluids can be mainly attributed to a NaCl–H 2 O–CaF 2 system of moderate to low temperature, low salinity, and low density. The ore-forming fluid has a meteoric water source, with the reaction between the fluid and wallrocks being the main mechanism for fluorite precipitation at relatively low temperatures.
