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. Owing to the hydrophobic property of diamonds, these stick to the grease affording a very clean diamond concentrate for final hand sorting.
The major steps in diamond recovery are liberation, gravity concentration using rotary pans, and diamond recovery on grease tables, followed by hand sorting.
The heavy mineral concentrates advance through an attrition scrubber to grease tables and hand-sorting for diamond recovery.
The final concentrate is fed onto sloping grease tables for removal of the diamonds.
