The depressing properties of sodium polyacrylate PA-Na for scheelite and fluorite were studied by micro-flotation tests, infrared spectroscopy IR, zeta potentials, X-ray photoelectron spectroscopy XPS, and density functional theory DFT. The flotation results reveal that the selective depression effect of PA-Na is better than that of sodium silicate, and PA-Na can depress fluorite more ...
Keywords scheelite, fluorite, calcite, regulator, flotation separation . INTRODUCTION . In scheelite flotation, gangue minerals such as Fluorite and Calcite have the same surfaceactive cation Ca-2 with scheelite minerals and strong binding capacity with the fatty
Jul 26, 2019 The flotation separation of fluorite mineral and calcite. Calcite and fluorite mineral can both be collected by fatty acid collectors and are both calcium minerals. It is difficult to separate them. For the flotation separation of fluorite mineral and calcite, the key point is to enlarge the flotation difference at suitable grinding fineness.
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
Fluorite ore is brittle and fragile. It is easy to produce many high-grade powdery ores during crushing, and there will be some loss in the process of gravity separation and manual separation. Therefore, the gravity separation and manual separation of fluorite ore tailings are often go to the flotation process to improve the concentrate grades.
Mineral processing equipment includes gravity separation equipment and flotation equipment Gravity separation equipment jig, only jig can deal with the coarse fluorite ore. Fluorite flotation equipment is similar with other mineral flotation equipment including crusher, ball mill, flotation machine etc..
Jul 01, 2018 Abstract. Read online. 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 only FIGURE of the drawing is a flow diagram showing a preferred method according to the invention for the separation of arsenic from fluorite ore, by means of a magnetic separation and by flotation of the arsenical pyrites present in the referred mineral.
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 andor 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 ...
Factors Affecting the Grade and Recovery of Fluorite. 1.Grinding particle size grinding fineness In the mineral processing, grinding fineness is one of the most important factors affecting the ore dressing index, which directly affects the final concentrate ore dressing index.Through processing condition test, it is found that within a certain particle size range, the flotation index of ...
Selective flotation separation of fluorite from calcite by application of flaxseed gum as depressant 1. Introduction. Fluorite is the most important fluorine industrial raw material and its products have been widely used... 2. Materials and methods. The pure mineral samples of fluorite and calcite ...
Apr 01, 2019 Due to its strong complexing ability with calcium ions Arena et al., 1983, EDTA may be used to effectively depress alkaline earth minerals such as fluorite in RE flotation. In the current study, the effect of EDTA on the separation of bastn site and fluorite was studied and the depression mechanism of EDTA on fluorite was systematically investigated through thermodynamic calculation,
Fluorite CaF 2 is the most important mineral source that produces fluorine-based chemicals and materials in a wide range of engineering and technological applications 1, 2 . In general, fluorite is associated with calcite CaCO 3 and separated from calcite through the
Jul 06, 2020 Gravity separation 1. Separation of fluorite and sulfide ore Usually, yellow medicine is used as a collector to float sulfide ore... 2. Separation of fluorite and barite The ore type of a fluorite ore dressing plant is fluorite-barite type, the main... 3. Separation of fluorite and quartz
Dec 01, 2020 Separating fluorite and calcite through flotation is difficult due to their similar Ca 2 sites on the adsorption surface of collectors. Psyllium seed gum, a reagent naturally derived from psyllium seed, was used for the first time as an efficient depressant in the flotation separation of fluorite and calcite.
Jul 01, 2020 Flotation separation of fluorite from calcite using sulfonated lignite as depressant 1. Introduction. Fluorite CaF 2 is one of the most important fluorine-bearing minerals and it is widely used in... 2. Materials and methods. The pure mineral samples of fluorite and calcite were purchased from ...
In short, the single-mineral flotation results show PA-Na has a more preferential flotation separation of scheelite from fluorite than Na 2 SiO 3 at pulp pH between 8.7 and 10. The flotation recovery of scheelite and fluorite with 75 mgL of 731 at the pulp pH 9.39.6 as the PA-Na concentration increased is
Calcite and fluorite can be separated by the adsorption-washing-flotation method using sodium dodecyl sulphate as collector 3 . The acid-grade fluorite concentrates can be obtained with oleoylsarcosine as a collector and quebracho depressant at pH 89 from ores containing more than 6 calcite 4 .
Apr 01, 2021 At present, the primary beneficiation approach of fluorite is flotation .In the deposits, fluorite is often associated with gangue minerals such as calcite and quartz, which share similar surface properties with fluorite i.e. solubility, crystal structure, hydrophobicity, and zeta potential, making the effective separation challenging to achieve , , .
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
Sep 03, 2020 To achieve the separation of calcite and fluorite, the pH value of the slurry must be adjusted, and a collector can be used to achieve a good separation effect. In the pH range of 8-9.5, using oleic acid as a collector, both types of ores can float, but in a weakly acidic medium, the floatability of calcite is relatively lower than that of ...
