We recommend that the gravity concentrator be placed on cyclone feed to generate the highest recoveries. However, it can also be used to recover minerals from the cyclone underflow and overflow within the circuit. Outside of grinding circuits, fine gold recovery can also be achieved from alluvial gold operations and from aggregate plants.

High gold recovery with fully fluidised cones. Our concentrator's leading-edge cone technology has been built on 40 years of innovation and is designed to capture the maximum amount of gold per cycle. Knelson is the only enhanced gravity concentrator with a fully fluidised bed allowing for upgrading throughout the entire cone surface.

Gold particles which are retained can be subjected to multiple passes through a gravity recovery device to ensure the chance of capture is maximised. By targeting the high recoveries of the cyclone and the high upgrade ratios of the Knelson Concentrator, even the finest liberated gold can be recovered into a relatively small mass

So a 2% difference in cyclone efficiency actually – for the gold retention – actually does have a substantial difference on overall gold recovery in the circuit. So this is one of the reasons that one of the best things an operator can do to improve the gravity circuit is make sure that the cyclones are functioning very efficiently when it ...

Gold particles were observed to be one to two microns in one dimension and 50 to 500 microns in the other two dimensions. This characteristic caused the gold to float across the conventional gravity tables and report to the tail. Gold was found to be concentrated in all cyclone underflow streams. The concentrations of the cyclone underflow streams
