SPECIAL METHODS OF SEPARATION

Special methods of separation:

  • Ore separation by color
  • Ore separation by shine
  • Ore separation by hardness
  • Ore separation by form
  • Ore separation by friction
  • Ore separation by elasticity
  • Ore separation by size (with selective crushing and grinding)
  • Ore separation by density (in air)
  • Separation of ores by ability to adhere to body surfaces (or other surfaces)
  • Separation of ores by ability of the mineral to obtain triboelectric charge through friction
  • Separation of ores by ability of mineral to crumble when heated (decriptation)
  • Separation of ores by ability of mineral to crumble when frozen
  • Separation of ore by reflectivity of mineral when using various types of physical radiations (optical methods, photometric separation, radiometric sorting, fluorescent separation)
  • (Amalgamation, Borax method of gold extraction)
  • (Sticky separation)
