In the flotation process, the collector is the key to achieve effective separation of bastnaesite from the co-associated minerals calcite, fluorite, barite, dolomite, quartz and feldspar [4], [5]. The common collector for bastnaesite is oxygen or nitrogen-containing hard base organic compounds, such as carboxylic acid, hydroxamic acid and ...

The flotation of bastnaesite, as a major mineral source of rare earth elements, attracting much attention in the mineral processing field, is challenging owing to the natural flotability of calcium-bearing minerals. To promote the application of flotation, we systematically investigated the flotation behavior of bastnaesite, barite, and calcite, …
Barite (BaSO4), a sulfate of barium (Ba) is the major industrial source of barium, and the heaviest nonmetallic mineral. BaSO4 has the mass proportion of 66 % …
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 ...
Barite deposit at Mangampet is one of the world's largest deposits containing around 61 million tonnes of recoverable barite. Beneficiation of low grade …
The general process of barite beneficiation includes crushing, grinding, screening, gravity separation, flotation and drying.According to the actual ore type, sometimes washing and magnetic separation processes are also included.JXSC our barite beneficiation process and equipment, impurities can be removed and the purity and …

The concentration of barite by gravity separation generates substantial quantities of fine-particle wastes, and it is estimated that ≈40% of the contained barite is lost to these waste streams. In this study, froth flotation was examined as a potential method for the recovery of fine-barite particles. The study included the use of kinetic …
The best performance was reached with the use of Petronate L (1000 g/t; pH 6.5) for barite flotation, leading to the obtention of a barite concentrate with a 95.1% BaSO⁴ grade answering the oil ...
The flotation separation of barite from calcite using sodium dodecyl sulfate (SDS) as the collector and sodium silicate (SS) as the depressant has been concretely studied in this paper.
The flotation recovery of bastnaesite was significantly affected by dissolved fluorite and barite species. After treatment with fluorite and barite supernatants, the …
Calcite depression through the flotation of its associated valuable minerals (such as barite, scheelite, apatite, monazite, cassiterite, etc.) could be accomplished by depressants (Table 3). Starch is the most common depressant for calcium mineral separation, which has a higher affinity towards calcite over apatite, thereby adsorbing …
The flotation flow sheet was modified to reject barren coarse and/or slime fractions from some of the samples, and one feed sample had to be scrubbed prior to flotation to remove residual flotation reagents. The cleaned concentrates had BaSO4 contents ranging from 95.0 to 96.9 percent, while recovering 81.2 to 95.9 percent of the barite in the ...
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 ...
Oxidized paraffin soap(C 12-16 COONa)is also widely used in quartz-fluorite, calcite-fluorite and barite-fluorite separation by flotation. Its collecting abilities are weaker than oleic acid, but its selectivity is better. The soap made from saponified waste oil can reach the flotation concentrate grade and recovery of ca. 98% and 86%, ...
2.4.2 Barite flotation in cell Two steps (roughing and scavenging) have been required. The roughing flotation has been carried out with petroleum sulphonate (1000 g/t) at pH 6. The sink
Micro-flotation experiments confirm that the flotability of bastnaesite is high at pH 6.5–8.5, while calcite floats at pH 8.0–9.5, and barite has little flotation response.
The jaw crusher is mainly used to crush the mined barite to reach the size range of the jig machine. Two-stage crushing process. It is recommended to use PE400*600 jaw crusher for the first stage of crushing, and PEF250*1000 fine jaw crusher for the second stage of crushing. After one stage of crushing, the product is conveyed to …

Using 1-octadecyl ester-1, 2-benzenedicarboxylic acid (OEBA) as a collector, the flotation separation of fluorite, calcite and barite was investigated in this paper. The micro-flotation results showed that OEBA efficiently floated out fluorite and barite from calcite at pH ∼ 9.0, and barite from fluorite at pH ∼ 11.0.

Abstract The effects of ultrasonic waves on the flotation of calcite, barite and quartz have been investigated in the case of single and mixed minerals. In the case of single minerals, ultrasonic treatment has a positive effect in the flotation performance of calcite and barite, while showing a negative effect in the case of quartz. Similar results were obtained in …

The flotation of rare earth minerals, which is of current interest in the mineral processing field, is challenging owing to the dissolution of gangue minerals. In this study, dissolved fluorite and barite species were found to significantly affect the flotation behavior of bastnaesite.
In the case of single minerals, ultrasonic treatment has a positive effect in the flotation performance of calcite and barite, while showing a negative effect in the case of quartz. Similar results were obtained in the case of mixed minerals. This has been attributed to the difference between collector adsorption mechanisms characterised by ...
