Using Knelson gravity concentrators, about 50% of the gold is easily liberated and recovered as free gold at Blanket Mine in Zimbabwe . Knelson gravity concentrators are the leaders in free gold recovery in Africa! Background Blanket started production in 1904. Early workers mined the visible gold sections of the pay shoots, pick the ...
Here is how a gravity gold concentrator (centrifuge) works as a separator: Make sure the concentrator has been correctly assembled and that all bolts have been tightened. If required, attach a funnel to the material feed inlet. If necessary, connect a hose to the tailings outlet. Place the concentrator on a raised structure such as blocks.
FL Knelson Concentrators are the market leaders in gravity concentrators, and are worth more than their weight in gold. Using centrifugal force and water injection processes, FL Knelson Concentrators create enhanced gravitational forces of up to 200 g''s to recover free gold, fine gold and any other precious metals or minerals with high specific gravities.
Gold Centrifugal Concentrator is an efficient gravity separation machine that is useful in the recovery of free gold in all ranges of particle size, especially useful for recovering fine gold which gets lost during the operation of gravitational concentrators. It is not only used for placer gold mining, but it can also be used for the recovery of natural gold from rocks that are hard, for ...
Dispelling the myth: There are abundant documented cases of FL Knelson Concentrators recovering extremely fine gold – "paint" or "powder" gold that floats on water – and in some trials and installations in Africa, FL Knelsons have recovered this very fine gold downstream of competitor products that claimed to be better suited for the job.
