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 slurry, indicating a very

fluorite ore Jinpeng Mining

fluorite ore :The beneficiation of fluorite ore is gravity separation and flotation process. The specificity of fluorite flotation: 1. Because industrial making hydrofluoric acid require calcium fluorite content>98% and silica <1%, fluorite flotation generally use 5-7 stages concentration; 2. When the PH of ore pulp is 8-11, the floatability is good.
