    Jun 11, 2020 The former two have been exploited in froth flotation in improving the flotability of mineral fines, which is called as carrier flotation ( Green and Duke, 1962; Atesok et al., 2001 ). The latter two are very detrimental to any beneficiation process, because no matter whether the coated particles are collected as concentrate or tailing, the ...

    Improving Fluorite Flotation Under Low Temperature and

    The authors provide insight into the problem of selective flotation of fluorite from quartz-fluorite ores. The flotation of fluorite mineral from ores by using acidized water glass as depressant has been studied for substitution of the commonly used depressant. It was found that the acidized water glass could achieve higher selectivity of fluorite minerals against gangue minerals in the ...

    Improving fluorite flotation from ores by dispersion. As it is noted, with dispersion processing treated ore slurry, the distributions (true distribution) of fluorite, calcite and quartz in the size fraction of minus 38 μm were 25.3%, 33.1% and 49.2%, respectively, suggesting that the gangue minerals in the ore sample, especially quartz, were much finer than fluorite.

    Abstract Flotation separation of carbonate fluorite ore is a puzzle in mineral processing. In this study, the flotation separation of fluorite from calcite using polyaspartate (PASP) as depressant and sodium oleate (NaOL) as collector was investigated, and the adsorption mechanism was analyzed by zeta potential measurement and infrared spectrum (IR) analysis.

    Feb 13, 2021 The flotation problem is largely one of impurity removal. The sulphide minerals are generally floated first, and then the fluorite is floated from the silica, calcite, and other impurities.

    At present, we commonly adopt the flotation method to remove the mineral impurities except fluorite in the fluorite ore to improve the content of CaF 2, among which the dispersion process is a very important technique and the selection of dispersants will have a direct impact on the contents of CaF 2 of the final products [7]. In this work, we ...

    Oct 12, 2016 In this study, citric acid was used as a dispersant to improve the flotation performance of hematite fines. The effect and mechanism of citric acid on the reverse flotation of hematite fines were investigated by flotation tests, sedimentation experiments, scanning electron microscopy (SEM), zeta-potential measurements, and X-ray photoelectron spectroscopy (XPS). The results of SEM …

    Aug 24, 2010 The authors provide insight into the problem of selective flotation of fluorite from carbonate-fluorite ores. It is found that oxyhydrate collectors used in combination with sodium fluoride provide rather high level of selectivity in fluoride flotation from poor high-carbonate ores and make it possible to eliminate high-temperature pulp treatment with acceptable reduction in the flotation ...

    Accordingly, a study for improving the fluorite flotation by dispersion processing has been carried out in this work. The fluorite flotation is performed by using oleic acid as the collector and quebracho as the depressant, which is a commonly used chemical scheme for fluorite flotation (Crozier, 1992;Raju and Prabhakar, 2000).

    Abstract: Separating fluorite from quartz and calcite by forth flotation can be both in weak-acidized (pH 6.0) condition and weak alkali (pH 9.0) condition. The experiment results have shown that ZnSO 4 can decrease the depression that water glass works on the fluorite, and acidized water glass has a selective inhibition on the silicate minerals. The close flowsheet protocolled in the experiment can obtain the …
