Fluorite is an important strategic mineral. In general, fluorite ores will contain a certain amount of calcite gangue mineral. Thus, they need to be separated from each other. For an economic separation, a reverse flotation process is used to float calcite gangue from fluorite. However, little information on the separation is available. In this study, a novel reagent schedule using citric acid ...

Experiments using a Hallimond flotation tube showed that although the flotation reagents solely differ in terms of spacer, their efficacy in terms of flotation recovery varied very much. Whereas on calcite at pH 10.5 only the monocarboxylate collector gave a high yield, on fluorite at the same pH both the monocarboxylate and the dicarboxylate ...

Fluorite flotation: please anybody suggest good depressants for silica and calcite in fluorite flotation. My specs are now: Raw fluorspar has CaF2 =60%, CaCO3=19.5% and SiO2=9.7%, I am already using water glass, pH=10, with oleac acid as collecter. Concentrate has CaF2=88.7%, eliminated silica to 0.43% but still there is CaCO3 about 5%.

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 ...
