  • Froth flotation - Wikipedia

    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

  • Gold Jig Mineral Processing Jigs

    The Gold Jig or Mineral Jigs are important of all types of alluvial gold concentrating device among all gravity separation methods; they are also the most complex and the practice of jigging in mineral processing is often viewed as an art rather than a science. Gold jigging has been referred to as being probably the most complex gravity operation because of its continuously varying hydrodynamics.
