The gravity circuit is fed from a dedicated pump on the cyclone feed pumpbox, with all tails and oversize stream recollected and pumped back to the ball mill feed. The screen undersize is fed to a centrifugal gravity concentrator. A batch of concentrate is produced every 45 minutes and fed to the intensive cyanidation unit (ICU) holding tank.
Initially designed to handle coarse concentrates from batch centrifugal concentrators, such as the Falcon, Knelson and InLine Spinner, the flexible, robust design is now used to successfully leach smaller volumes of even the finest gravity and flotation concentrates. The well mixed horizontal drum design gives the ILR the flexibility to handle any leaching chemistry and reagent regime.
Jan 25, 2019· Abstract: The present invention is a segmented bowl for a batch centrifugal concentrator constructed from a plurality of segments that are each placed adjacently to one another, so that each segment is in intimate contact with its neighbouring segments, so that when a sufficient number of segments are put into place, they form the bowl of the batch centrifugal concentrator.
of centrifugal and gravity machines, such as Knelson and Falcon concentrators, however the subsequent recovery of gold is relatively inefficient and subject to security problems. The InLine Leach Reactor (ILR) offers a new method to recover over 95% of gold in concentrates using a simple, secure leaching process. The InLine Leach Reactor is of

Other batch centrifugal concentrators perform this function using water spray units that require distilled water on site and continuously supplied to the unit, complicating the instrument. In addition, other concentrators use higher g-forces to speed up the process, however this can promote contamination and other problems associated with ...
Of the Centrifugal devices developed, Kelsey Jigs, Knelson, Falcon, and Mozley MGS –the Falcon Concentrator has emerged as the most useful for fine gravity and flotation beneficiation. Fine Screening has come a very long way –e.g. Screens USA can now screen down to 45 microns, and such screens are being specified for Primary
