Spirals

Spiral separators, or spirals for short, are a versatile method of gravity separation that can deal with a comparatively wide size range Separation is achieved as a result of centrifugal forces induced by slurry running down the spiral, which forces lighter minerals to the outer bend whilst heavier minerals stay closer to the central axis....

Gravity separation

Gravity separation is one of the oldest mineral processing techniques yet, with modern developments, it is still to the fore Gravity concentration is, essentially, "a method of separating particles of minerals of different specific gravities by reason of their differences in movement in response to the joint simultaneous actions upon them of gravity and one or more other forces" (Taggart ....

Gravity Spiral Separator with Different Pitch

As for the 1500mm spiral separator, the disposition width is greater with the increasing mineral weight; as for the same distribution width, the grade of concentrate is increased by the addition of pitch It is suggested that replacing the 1500mm with 900mm to optimize the gravity separation process...

Gravity Separation

Gravity separation uses differences in specific gravity (SG) between various minerals to achieve a separation, and is normally a wet process although examples of dry gravity separators exist Gravity separation works best when there is a large difference in the SG in the minerals to be separated, and the particle size is similar and not ....
