CONT: [Most] processes involve concentration of ores with water, but there are equivalent processes employing air as the separating medium. Pneumatic jigs and tables operate on the same principles of gravity separation as wet jigs and tables but find use in desert regions where water is scarce and on ores that are best treated dry, such as asbestos, which depends upon the light, fluffy nature of the mineral for efficient concentration.
OBS: air jig: term standardized by ISO.
