Gravity separation : ALS

ALS provides gravity separation in combination with other techniques to identify and optimise the process flowsheet for the target mineral. Gravity separation is achieved based on the difference in specific gravity SG shape and particle size of the valuable minerals or metals as compared with the gangue or host rock and the carrying medium.

Dense Medium Cyclone

From the early 1960’s until the mid 1980’s dense medium cyclone circuitry design technology did not change appreciably. The basic design which was both highly flexible and highly efficient was consistent with technology developed by the Dutch State Mines “DSM” in the mid 1940’s. During this period the “typical” dense medium cyclone circuit was designed to process raw coal ...

How Gravity Separation Works to Recover Metals and …

Gravity concentrators use the same principles of gravity separation at higher velocities. While conventional gravity separation happens at one G force the Falcon SB uses up to 200Gs to concentrate microscopic particles as small as 20 microns. The same principles apply just at a smaller scale. Dense particles will settle first and light ones ...
