Gold Centrifugal Concentrator Suppliers and Manufacturers

Gold Centrifuge Concentrator is a new type of gravity concentration equipment for concentrating gold and other high density minerals. Gold Centrifuge Concentrator is kind centrifugal concentration equipment. It can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold, replacing amalgamation. Gold centrifugal concentrator is also used to recover gold from the old tailings

Centrifugal gold concentrator is a relatively new type of gravity concentration apparatus. The machines of pioneer s stlb series concentrator utilise the principles of a centrifuge to enhance the gravitational force experienced by feed particles to effect separation based on particle density. The key components of the unit are a cone shaped "concentrate" bowl, rotated at high speed by an electric motor and a pressurized water jacket encompassing the bowl. Feed material,typically from a ball mill discharge or cyclone underflow bleed, is fed as a slurry toward the centre of the bowl from above.The feed slurry contacts the base plate of the vessel and due to its rotation, is thrust outward.The outer extremities of the concentrate bowl house a series of ribs and between each pair of ribs is a groove. During operation the lighter material flows upward over the grooves and heavy mineral particles (usually of economic value) become trapped within them. Pressurized water is injected through a series of tangential water inlets along the perimeter of each groove to maintain a fluidized bed of particles in which heavy mineral particles can be efficiently concentrated. Centrifugal gold concentrator is an efficient equipment for recovering free gold in all particle size ranges,specially for recovery of fine gold which is lost during the operation of the gravitational concentrators(sluice boxes and jigs). It can be used not only for placer gold mining, but also for recover the natural gold from hard rocks, to replace amalgamation, and recover gold from the tailings.

Description The centrifugal concentrator, a kind of gravity separation equipment, is suitable for the separation of heavy medium minerals that have enough specific gravity differences. STLB concentrator is kind centrifugal concentration equipment. It can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold, replacing amalgamation. It is also used to recover gold from the old tailings. Since 1985, three models have been developed. Application shows that the recovery can be as high as 99%, especially for the case in recovering the natural gold in lode ore with 65% of the ore having a milling size of 0.074mm, the recovery for the natural gold is expected up to 98%. For those natural gold of 0.004mm in particle size, the recovery is 97%. The cleaning up cycle is 1~4 hours. And the upgrade ratio is up to 1,000 times. Working Principle Water jacket centrifugal concentrator is forced by centrifugal force increases mineral centrifugal acceleration, the minerals in the centrifuge spins a few times to get the equivalent in gravity state, then the proportion of mineral difference is magnified several times, Together with recoil mineral water to prevent compaction, thereby fine, mineral beneficiation achieve good results.
