improving fluorite flotation from ores by dispersion

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 ...

    Selective flotation of fine ingrained carbonate fluorite

    Jul 05, 2014 The studies into the fine-ingrained high-carbonate fluorite ore concentration show that increasing of pulp dispersion uniformity results in higher selectivity of flotation. The researchers find out availability of quality fluorite concentrate in processing of low-grade ore with carbonate index less than 1 at CaF2 recovery up to 70%.

    Jan 08, 2021 At this time the fluorite ore grade is high, but the recovery rate is low. It can be seen that increasing the slurry temperature appropriately can also improve the fluorite flotation index. 03 Correct selection of flotation reagents and dosage. The fluorite flotation reagents mentioned here mainly focus on collectors, inhibitors and pH regulators.

    Flotation separation of fluorite from calcite using

    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.

    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 ...

    The Role of Water Glass in the Flotation Separation of

    Fluorite is the principal mineral of fluorine and usually coexists with quartz in deposits. The removal of fine quartz in fluorite concentrate is the main problem in fluorite flotation. In this study, the flotation tests on fluorite, quartz and a weight equivalent mixture (all less than 10 μm) using water glass (with different modulus) as depressants and sodium oleate as collector were conducted.
