Flotation tests showed that the best results in terms of fluorite metallurgical recovery were 82.8% and 87.9% for new collectors DP-I and DP-II respectively, for a dosage of 100 g/t and using pneumatic cell. Additionally, in terms of fluorite grade, DP-I showed the best results, achieving 79.7% of CaF2 in roughing step for a dosage of 100 g/t.
The flotation process is divided into grinding, classifying, agitating, flotation and other processes. Due to the high requirements for concentrate grades, multiple flotation concentration separations more than 6 times, and the fluorite floatability is relatively good, usually only one scanning separation is required.

When ...
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
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

Mixed flotation of fluorite (fluorspar) and barite flotation, and then separate them. In mixed flotation, obtain mixed concentrate with oleic acid as a ...
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 concentrate.
General Treatment Scheme for Upgrading Fluorite Ores Flotation is the usual method for concentrating fluorite to a commercial grade product. Due to the difficult prN-Jblems encountered when trying to selectively float fluorite from its associated gangue minerals and produce high grade commsrcial
Apr 24, 2019 In general, the flotation process of the barite type fluoride ore is divided into two steps, one is combination flotation that obtains the combination of concentrate both of barite and fluorite, another is flotation that separation the barite and the fluorite from the combination concentrate. Flotation of the first step Na2CO3 as the conditioner of PH value, oleic acid as
Fluorite ore processing methods which is one roughing repeatedly choice,as a collector agent rougher with oleic acid or its substitute. The process is simple, low-cost advantages can be selected from the high calcium fluorite ore grade fluorite concentrate with a low content of calcium carbonate.
Apr 01, 2021 The mixture of sodium silicate and aluminum sulfate has also been used as the depressant in fluorite flotation, aiming at the elimination of sulfate minerals and calcite, and named as the A-3 series depressant . Compared with water glass, the grade and recovery of fluorite concentrate are increased by over 10% and 3%, respectively . Generally, two
The U.S. Bureau of Mines investigated column flotation for recovery of a high-grade fluorite (caf2) concentrate and byproduct concentrates from the Fish Creek fluorite deposit in Eureka County, Nevada, The recovery scheme consisted of (1) grinding the ore to minus 48 mesh, (2) fluorite rougher and cleaner flotation, (3) desliming the rougher fluorite flotation tailings at
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 ...

Oct 21, 2017 The magnetic iron removal was moved from the rougher silicate concentrate to the mica flotation tailings stream. Column flotation also resulted in higher grades of fluorspar, mica, and beryl products with better recovery. Fluorite Flotation. Water temperature was found to be an important factor in continuous flotation of fluorite.
This fluorite ore is difficult to beneficiate. Because the flotation properties of fluorite and calcium carbonate are the same, it is difficult to separate fluorite and calcium carbonate by conventional beneficiation methods. Qualified fluorite concentrate can also be obtained by flotation with special beneficiation methods and special reagents.
