  • Flotation and entrainment behavior of minerals in talc

    The main aim of a flotation process is to recover the valuable part of the ore with minimum gangue contamination by different mechanisms, such as entrainment. In this study, the flotation rate and recovery of talc and entrainment of fine calcite particles were investigated using individual minerals and a mixture of talc and calcite. The effects of various frothers were tested. The results

  • Flotation separation of molybdenite from chalcopyrite

    01/09/2020· Therefore, the flotation separation of molybdenite from chalcopyrite should be conducted at pH 8, which is very close to neutral and is economical for Cu-Mo flotation separation in commercial scale.

  • Flottation — Wikipédia

    La flottation est une technique de séparation fondée sur des différences d' hydrophobicité des surfaces des particules à séparer. Elle est utilisée en minéralurgie pour séparer des minéraux entre eux et dans le traitement des eaux usées pour éliminer les graisses.

  • Froth flotation Wikipedia

    The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement. Phosphates and coal are also upgraded (purified) by flotation technology. Prior to 1907, nearly all the copper mined in the US came from underground vein deposits, averaging 2.5 percent copper. By 1991, the average grade of copper ore mined in the US had fallen to

  • Définitions : flottation Dictionnaire de français Larousse

    (anglais floatation ou flotation) Définitions de flottation. Procédé de séparation d'un mélange de corps finement broyés, utilisant la propriété qu'ont certaines substances en milieu aqueux de fixer des bulles d'air, acquérant ainsi une densité artificiellement réduite. Action d'amener, à l'aide de petites bulles d'air, les impuretés à la surface de l'eau à épurer. VOUS

  • Flotation ore dressing Britannica

    Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to

  • Flottation par moussage — Wikipédia

    Histoire. Historiquement, l'extraction minière a été la première industrie à utiliser ce procédé à grande échelle, où il a été une des technologies les plus utilisées au XX e siècle. Il a été ainsi qualifié de « la plus importante opération élémentaire utilisée pour la récupération et l'enrichissement des minerais sulfureux [2] », par son intérêt dans l'extraction du

    10/06/2000· Plus tard, ce procédé a été appliqué à la séparation solide-liquide (flottation de précipité) et à l’extraction d’ions en solution (flottation ionique). Le principe de la flottation des minerais est le suivant : les particules solides sont mises en suspension par agitation dans de l’eau après qu’un broyage en humide, plus ou moins poussé, ait libéré de la gangue l
