After evaluating the flotation behavior of the individual minerals under various circumstances, the efficiency of the selective separation of barite from quartz was examined using one gram of a 1:1 wt mixed sample (0.5 g barite and 0.5 g quartz). The flotation experiments were conducted at pH = 3, 20 min of treatment time, and the cell ...

The single minerals flotation results revealed that barite slimes could be selectively depressed by gelatinized starch (GS), while WG had little effect on the floatability of barite and fluorite ...
Effect of CA concentration on the flotation of barite and fluorite at pH 8.5. [NaOl: 1.5 × 10 −4 mol/L]. Analytical-grade NaOl and CA were used as the collector and depressant, respectively. NaOH and HCl were utilized as pH adjusters. Distilled water with a resistivity of 18.2 mΩ cm was used for all the experiments.
Liu et al. [24] selected a new system with high selectivity and strong collecting ability, α-BLA (bromododecanoic acid) system, which showed promise in their research. The effect of citric acid on the flotation of fluorite and barite were investigated. It was observed that the floatability of the two minerals differed when citric acid was used as a depressant.
The results have shown that a dosage of 200 g/Ton of SDS recovers more than 80% of the barite (i.e., BaO) after performing a 20 minutes flotation at pH 9. A 5-minute flotation is enough to recover at least 60% of BaO with the highest grade, which was considered the target recovery of barite for the present project.

Currently, flotation is one of the commonly used method to concentrate barite from real ore, and the fatty acids are the widely-used anionic collectors in the flotation of barite and other oxidized minerals because of the strong interaction occurred between fatty acids and barium/metal site at minerals surface [[6], [7], [8], [9]].However, as one of the common gangue …
Mineral flotation tests show that barite, deionized water flotation after microwave treatment, recovery increased by 2.67%, 3.35%, respectively, while the pulp and the pulp of chemically added ore ...
9.0, the best floatability of barite was obtained, with a recovery of approximately 91 %. As for calcite, the floatability was good with a recovery higher than 90 % over the same pH range tested for the barite flotation. When using NaOL as the collector, the optimum flotation pH of barite ranged from 6.0 to 8.0,
Definitive choice of optimal flotation requirements focused on Petronate L (1000 g/t ; pH 6.5) for barite flotation and on Flotbel R171A (100 g/t ; pH 9) for fluorite, combined with potassium …
4. Technical Features of the Gravity-Flotation Separation. Targeted Combination of Processes: The gravity-flotation process exploits the differences in density and surface properties between barite, fluorite, and gangue minerals. Gravity separation reduces the load on flotation by discarding gangue early, while flotation refines the fluorite ...
Barite is an important strategic non-metallic mineral. China has rich barite resources. Its reserves, output and export volume rank first in the world. However the situation of low export price has existed for a long time. Based on the characteristics of barite ore at the present stage, this paper introduces the different dressing methods of barite ore in China.
In this research, it was found that lauryl phosphate is also a promising collector for barite flotation. Results from microflotation, contact angle, and zeta potential indicate that …
Barite quality is important to drilling fluid performance because low grade barite products introduce increased amounts of low gravity solids (LGS) for any application and the
The flotation experiments showed that under the SDS flotation system, when the pH was 9.0 and the amount of depressant β-CD was 900 g/t, the barite recovery and density reached the highest values, which were 87.41% and 4.042 g/cm 3, respectively. Zeta potential experiments, contact angle analysis, and FTIR analysis indicate that β-CD adsorbed ...
The development of new collectors to separate fluorite from barite is urgently needed in mineral processing. In this study, the flotation behavior of fluorite and barite was studied using sodium ...
An experiment was conducted to study how varying the NaOL dosage affects the flotation of barite and fluorite at a slurry pH of 9. Fig. 4 displays that the recovery of fluorite and barite were less than 50 % at NaOL dosage of 5 × 10-5 mol/L. Increasing the NaOL concentration to 1 × 10-4 mol/L greatly improved the recoveries, with ...

Collectors (surfactants) play an important role in flotation recovery of fluorite, barite and calcite (Foucaud et al., 2018, Lv et al., 2022).Fatty acids could adsorb on the surface Ca(Ⅱ) or Ba(Ⅱ) sites of the three minerals, and were their dominant collectors (Chen et al., 2019, Zhou and Lu, 1992, Zhou et al., 2013).While, fatty acids suffered from the low selectivity in flotation ...
In the case of barite flotation, although the recovery of barite slime ( 10 µm fraction) presented a slight drop, it is still main at >80% value. These findings revealed that the flotation separation of fluorite and barite was nearly impossible without the addition of a depressant. In our previous study, GS was tested as a depressant in the ...
The Nigeria Geological Survey Agency (NGSA) was the first to report on Barite mineralization in Nigeria in its memorandum report 1959 [11], but no interest was shown with regards to its exploration at that time [12].However, between 1975 and 1980, the Nigerian Mining Corporation carried out exploratory work on barite deposits in Azara, Nasarawa State in North …
