how to flotation fluorite


5. In the froth flotation of fluorite from a calcareous gangue with a fatty acid collector for the fluorite in an aqueous alkaline ore pulp, the improvement which comprises activating said pulp for the selective flotation of fluorite by adding sodium bisulfite in amount within the range of 1/4 to 2 lbs./ton.


Regarding fluorite, the flotation recovery of fluorite changed slightly as compared to the result for using NaOl alone. Therefore, the optimum pH to separate fluorite from barite is deemed to be pH 8–9.5 when using TSP as the depressant and NaOl as the collector.


Abstract. The authors provide insight into the problem of selective flotation of fluorite from carbonate-fluorite ores. It is found that oxyhydrate collectors used in combination with sodium fluoride provide rather high level of selectivity in fluoride flotation from poor high-carbonate ores and make it possible to eliminate high-temperature pulp treatment with acceptable reduction in the ...

Separating fluorite from quartz and calcite by forth flotation can be both in weak-acidized (pH 6.0) condition and weak alkali (pH 9.0) condition. The experiment results have shown that ZnSO4 can decrease the depression that water glass works on the fluorite, and acidized water glass has a selective inhibition on the silicate minerals. The close flowsheet protocolled in the experiment can ...


encountered when trying to selectively float fluorite from its associated gangue minerals and produce high grade commsrcial products by flotation, the process flowsheets are complex, with many stages of grinding, conditioning and flotation, with tailings streams being recycled to earlier treatment stages.

sulphide ores [13], especially for the flotation of fluorite [7]. However, the flotation separation of fluorite from quartz using water glass is not so effective, as there is always a small amount of fine quartz (less than 10 m) in the fluorite concentrate. The floated fine quartz in fluorite concentrate has been reported to be the result of ...


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. Another, increasing the temperature of ore pulp can ...


Flotation separation of carbonate fluorite ore is a puzzle in mineral processing. In this study, the flotation separation of fluorite from calcite using polyaspartate (PASP) as depressant and sodium oleate (NaOL) as collector was investigated, and the adsorption mechanism was analyzed by zeta potential measurement and infrared spectrum (IR) analysis.


During the flotation of fluorite, the regime of reagent and grinding fineness are important factors influencing fluorite flotation, which can't be decided blindly. It is suggested that carrying mineral processing experiment with qualified ore dressing laboratory or ore dressing equipment supplier. To avoid economic loss, technological process ...

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 ...


Separation of fluorite and sulfide ore. The sulfide ore contained in fluorite is floated with xanthate collector, and then fatty acid collectors float fluorite. In flotation of fluorite, it can be also feasible to add a small amount of sulfide mineral to inhibit residual sulfide mineral, and ensures the quality of fluorite …
