The present invention relates to aprocessfor removingantimonyfrom hydrofluoric acid solutions which contain Ta/Nb and have an acidity of >18 N, by addition of a base metal reducing agent to the solution and heating at 40 to 60° C. for 4 to 8 hours.

Therefore, in thejigging process, the bed is in a loose state as much as possible to improve theprocessingcapacity of the jig and improve the sorting effect. (4) The influence of the size and shape of the ore particles on the stratification mainly occurs during the period of relative movement between the ore particles and the medium.

Cleavage/Fracture: Fluorite is a unique mineral when it comes to its cleavage due to its four directions of perfect cleavage, something not seen many common minerals. The shape of fluorite often resembles an octahedron. (3) Crystal Form: Fluorite crystals are equal in dimension because they have an isometric crystal habit. Fluorite typically takes on a cubic form, although other complex forms are not uncommon.
