Study on Knelson Concentrator Gravity Separation of a Polymetallic Ore Bearing Gold The major methods of recovering gold are gravity separation, gold flotation, cyanide. In fact, traditional gravity separators, such as jig machine, spiral chute, gold shaker table, have the shortages of low beneficiation ratio and low productivity.

However, in a production environment, recovery rates using gravity separation methods for gold particles down to 200-300 mesh begin to decline using any gravity separation method. We claim 99% recovery of free gold down to 100 mesh and 80% to 90% recovery down to 200 mesh.

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.

A centrifugal extractor—also known as a centrifugal contactor or annular centrifugal contactor—uses the rotation of the rotor inside a centrifuge to mix two immiscible liquids outside the rotor and to separate the liquids in the field of gravity inside the rotor. This way, a centrifugal extractor generates a continuous extraction from one liquid phase (fermentation broth) into another ...
