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)
