This paper introduced the characteristics of fluorite resources in our country, and pointed out the causes existing in the difficulty of flotation separation. Summarized the research status and the direction development of fluorite ore collector, and found out chemical or biological modification and combined reagents was an effective method on improving selectivity of fatty acid collector ...
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 equations to estimate the variables …

The effect of pH on the flotation recovery of barite and calcite using SDS and NaOL as collectors was studied by micro-flotation tests, as shown in Fig. 3. It could be seen from Fig. 3 that the flotation recovery of barite with SDS increased in the pH range from 8.0 to 10.0, and at an optimum pH of approximately
Barite Flotation Separation Process. If barite ore contains a high barium sulfate (BaSO4) content, it is associated with gangue minerals such as quartz, calcite and fluorite. …
By Mark Leatherman. Barite has got to be one of my favorite minerals to collect for a variety of reasons: 1) its unique heft for being a nonmetallic mineral, 2) the variety of colors and conditions it can form under, …
Laboratory tests indicated that the barite concentrate assaying 95 % BaSO4 could be obtained with a recovery of around 70 % in a single stage column flotation. The recovery was improved …

NVT [moles (N), volume (V), and temperature (T)] together with Hoover's thermostat were used. The integration of the particle motion was evaluated by the leap-frog method with a time step of 1 fs (femtosecond). The
Barite magnetic separation. A wet magnetic separator is usually used to select some iron-bearing materials such as siderite, which are used as barite feedstock for baryte based pharmaceuticals with very low iron content. …
Barite and fluorite are released at, at least, 82,5% in the fraction 0,1–0,2 mm (65–150 mesh) and the gangue is released at 82% in the same fraction. 2. Experimental conditions in cell flotation …
Barite has numerous applications including barium mud for oil well drilling, manufacture of elemental barium, filler for paper and rubber industries, and contrast material for X-ray radiology for the digestive system. Currently, froth flotation is the main method for the beneficiation of barite using fatty acid as a typical collector. In this research, it was found that …

The micro-flotation performance found that OAHD realized an efficient flotation of ilmenite under low concentration of 1.0 × 10 −5 mol/L under around pH 8.0, and the flotation recovery rate of ilmenite reached about 94.2%, which was about 35.8% higher than that of NaOL. The morphology of ilmenite observed by AFM probed the self-assemble ...
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 results of FT-IR, XPS, and zeta-potential measurements indicate that there is chemical adsorption of SHA on the bastnaesite surface, and physical adsorption also occurs.
