    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
  • Froth flotation - Wikipedia
    The minerals that do not float into the froth are referred to as the flotation tailings or flotation tails These tailings may also be subjected to further stages of flotation to recover the valuable particles that did not float the first time
  • Flotation - an overview | ScienceDirect Topics
    Flotation is defined as a separation process in which air bubbles attach to hydrophobic particles, causing them to rise to the surface of a liquid for removal This process is enhanced by the addition of collectors that impart hydrophobicity to the particles and frothers that reduce surface tension, stabilizing the froth
