  • differential adsorption of hydrolytic polymaleic anhydride

    Feb 01, 2021 · Therefore, it is of importance to seek efficient methods to recover apatite from dolomite. Flotation, a separation and concentrate process that utilizes the different physicochemical properties of minerals to remove gangue minerals from valuable minerals , , , , is regarded as the most effective method for removing dolomite from apatite , ,

  • selective adsorption of a high-performance depressant onto

    Oct 15, 2020 · The micro-flotation of dolomite and magnesite was carried out in a laboratory flotation device (mechanical agitation) with a 30-mL detachable cell and a stirring speed of 1992 rpm. The flotation slurry was prepared by adding a single mineral (2 g) or artificially mixed minerals (1.2 g magnesite and 0.8 g dolomite) into 25-mL DI water in the flotation cell

  • improving flotation separation of apatite from dolomite

    Sep 01, 2020 · Moreover, the selectivity index (SI) was used to evaluate the impact of PAMS on the separation features of apatite and dolomite by direct flotation, and its calculation formula is expressed as follows (Cao et al., 2019b): (1) SI = ε C A ε T A × ε T D ε C D where SI is the selectivity index; ε C A and ε C D express the apatite and dolomite recoveries in concentrate, respectively; ε T A and ε T D represent …

  • flotation research on dolomite-containing magnesite ore

    In the flotation system of sodium oleate, magnesite and dolomite had good floatability but quartz could hardly be floated. Sodium hexametaphosphate inhibited dolomite more strongly than magnesite

  • promising options for solving thedolomiteproblem of the

    The flotation process could achieve a concentrate with the lowest MgO content, but it is the most expensive approach. Adding a dolomite is inexpensive and easy, but the effect is limited

  • mechanism of separating pyrite and dolomite by flotation

    The separation of magnesite from dolomite was studied by flotation tests, X-ray photoelectron spectroscopy (XPS), and zeta potential measurements in the presence of calcium ion (Ca²⁺) dissolved

  • flotationseparation of carbonate fromsulfide minerals, i

    Jul 01, 2004 · This is usually achieved by direct flotation of the gold and sulfide minerals into a bulk flotation concentrate. However, if the flotation recoveries of gold and sulfide are unsatisfactory, reverse flotation of the carbonate minerals is a possible alternative. In this study, calcite and dolomite were used as representative carbonate minerals, and pyrite and chalcopyrite as representative sulfide minerals to …

  • novel technique for the separation ofdolomitefrom

    The screened particles are de slimed (150 Mesh) (0.105 mm) and conditioned (2.5 minutes) at a pH 10. The concentrate is reconditioned ( 30 seconds) with sulfuric acid (maintains pH 4 5). This is followed by f lotation to remove dolomite. Final processing involves cationic flotation of the fine silica from the dewatered dolomite flotation cell
