Diamond recovery from concentrate will be through magnetic separation and X-ray technology supplied by DebTech, with no grease table
Two years later, Redaurum constructed a 10 t/h test plant on site which utilised a rotary diamond pan for concentration and a vibrating grease table for diamond recovery.
The heavy mineral concentrates recovered from the pans are passed with water over a vibrating grease table.
The major steps in diamond recovery are liberation, gravity concentration using rotary pans, and diamond recovery on grease tables
, followed by hand sorting.
The final concentrate is fed onto sloping grease tables
