  • Effect of solids on pulp and froth properties in flotation

    Apr 25 2014 · Froth flotation is a widely used process of particle separation exploiting differences in surface properties. It is important to point out that overall flotation performance (grade and recovery) is a consequence of the quality and quantity of the solid particles collected from the pulp phase transported into the froth phase and surviving as bubble-particle aggregates into the overflow.

  • Flotation columns Getting the most from fine oresOutotec

    Column flotation devices were re-introduced for mineral processing by Boutin and Wheeler in Canada in 1967 when wash water addition to the froth was used to eliminate entrainment of hydrophilic materials to the float product. By the late-1980s column flotation had become a proven industrial technology in the mineral industry.
