Experimental Research on Recovery of Fluorite from a …
Flotation tailings of a polymetallic mine in Inner Mongolia contain fluorite resources. Due to the influence of the tungsten-tin flotation reagent and the ore embedded characteristics in the early stage, the fluorite flotation concentrate grade is up to 92%, and the recovery is about 30%. The fluorite resources in the tailings were not effectively …Web

Before fluorspar can be used to make hydrofluoric acid, the raw ore must be physically concentrated and purified. Ceramic and acid gr ades of fluorspar are concent rated (not shown) by crushing and grinding fluorspar, and purified by froth flotation. First the fluorspar is crushed and ground. Then lead and zinc sulfides are preferentiallyWeb

Investigation on the flotation separation of fluorite from celestite
As can be seen from Fig. 5(a), with the increase of pH, the flotation recovery of fluorite and celestite first increased significantly, and then decreased slowly after reaching the maximum value. For fluorite, the maximum recovery of 98.11% was obtained at pH 6.0, while the recovery of celestite was 73.82% at the pH. ConclusionWeb
