  • Hydrophobicity Of Minerals Determined By Atomic Force

    Apr 28, 2014 The mineral separation process flotation is fundamentally relying on hydrophobic interactions, which are still not entirely understood and heavily discussed in literature. Here, various possibilities to determine hydrophobic properties of mineral surfaces in water using the concept of colloidal probe atomic force microscopy are introduced.

  • Introduction To Mineral Processing Or Beneficiation

    The use of flotation for recovery of fine coal is also widely practiced. The flotation process begins with a modification of the surface properties of the desired mineral. The addition of surfactants renders the mineral surface hydrophobic (water-hating), so that the mineral may preferentially adhere to air bubbles and float to the surface. The ...

  • Flotation Ore Dressing Britannica

    Most kinds of minerals require coating with a water repellent to make them float. By coating the minerals with small amounts of chemicals or oils, finely ground particles of the minerals remain unwetted and will thus adhere to air bubbles. The mineral particles are coated by agitating a pulp of ore, water, and suitable chemicals; the latter bind to the surface of the mineral particles and make them hydrophobic.
