separation of apatite and fluorite in flotation

  • The role of sodium alginate in the flotation separation of

    2020-08-01· The flotation separation of apatite from dolomite can be achieved under the reagent system of adding 20 mg/L SA followed by 1*10 −4 mol/L NaOl in pH 8–11. The contact angle tests and adsorption tests indicate that depressant SA absorbed onto both apatite and dolomite surfaces and the adsorption intensity of the latter was greater than that of the former.

  • Improving flotation separation of apatite from dolomite

    To explore the impact of PAMS on the flotation separation of apatite from dolomite, the flotation experiments on mixed apatite and dolomite minerals as feed were performed at pH 9.00, and the results are presented in Table 1. It is worth noting that the mass ratio of apatite and dolomite was 1:1 and the grade of P 2 O 5 was 20.36% in initial feed.

    Flotation tests were performed on a skarn ore to attain the selective separation of scheelite (CaWO 4) from fluorite, apatite, and silicates.Fluorite and apatite constitute common gangue minerals in scheelite ores. Due to their similar surface properties and good floatability, the separation of scheelite from fluorite is particularly difficult.

  • Selective adsorption of sodium polyacrylate on calcite

    2020-06-15· In the flotation separation of apatite and calcite, fatty acid collectors are adsorbed on both mineral surfaces owing to the presence of the same calcium ions on the cleavage planes,, . Therefore, the floatability of both minerals is excellent and the flotation selectivity is very low.

    2015-05-01· Flotation recovery was studied in the pH range of 2–12 for apatite, and 6–12 for calcite (due to the alkaline nature of CaCO 3 it was not feasible to measure at a pH lower than 6) for a collector concentration of 2 × 10 −4 M with the data obtained presented in Fig. 2a and b respectively. Even though the structures of the collectors are relatively similar there are obviously considerable
