Flotation of fluorite from ores by using acidized water

May 01, 2013· Fluorite flotation tests were carried out with the actual and new schemes. Fig. 2 showed the photographs of the tailing slurries after being settled for 96 h from the flotation test with the actual scheme and being settled for 2 h from the test with the new scheme. With the actual scheme (Fig. 2a), 96 h of sedimentation did not produce clarified water in the tailing

The anionic flotation of fluorite from barite using

Jul 20, 2020· The flotation of mixed minerals confirmed that GS can be used as the efficient depressant in the anionic flotation of fluorite from barite. Zeta potential measurements and XPS results implied that the adsorption of GS on the fluorite surface was physisorption while hydrogen bonding might dominate the interaction between GS and barite surface.

Reverse Flotation Separation of Fluorite from Calcite: A

Fluorite (CaF2), as an important strategic mineral source, is usually separated from calcite by the common froth flotation method, but this separation is still not selective enough. The development of a selective collector and/or depressant is the key to achieving high selective separation. 1-Hydroxyethylidene-1,1-diphosphonic acid (HEDP or H4L) is widely used as an environmentally friendly
