The anionic flotation of fluorite from barite using

Jul 20, 2020· As shown in Fig. 2, the flotation recoveries of barite and fluorite were very high with NaOl alone, indicating the poor selectivity between fluorite and barite in the absence of GS.With the addition of 75 mg/L GS prior to NaOl, the flotation behavior of fluorite was not affected at pH 6.0-8.0 but slightly decreased to a certain extent at pH > 8.0.

Intensifying fine-grained fluorite flotation process with

Accordingly, thorough grinding is necessary to extract high-grade fluorite from lean ore, leading to particles with small dimensions. When the particle size reduced to 37 μm, the large specific area leads to difficulties in stable operation for conventional flotation, due to ineffective attachment between millimeter-scale bubbles and the tiny

Flotation separation of fluorite from calcite by using

Dec 01, 2020· The flotation separation of fluorite from calcite is realized when the adsorption amount on calcite surface is higher than that on fluorite surface (Tian et al., 2019a). Nevertheless, the depressive effect is greatly affected by the pH value ( Tian et al., 2019a ), with the excellent selective depressive effect only achieved in the pH range of

Reverse Flotation Separation of Fluorite from Calcite: A

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 most common method of froth flotation [3,4].However, the selective flotation separation remains a challenge since both

Testing of New Collectors for Concentration of Fluorite by

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.

Reverse Flotation Separation of Fluorite from Calcite: A

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

Flotation separation of fluorite from calcite by using

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

Fluorite flotation process Yantai Jinpeng Mining

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 Scheelite from Fluorite Using

The flotation recovery of scheelite and fluorite keeps at about 75% and 10%, respectively, at the pulp pH 9.3~9.6 and PA-Na concentration from 30 to 50 mg/L. IR spectra results suggest that PA-Na has a chemical effect on the surface of scheelite and fluorite. The zeta potential of fluorite becomes more negative than that of scheelite after PA-Na
