The Optima Concentrator

The Optima Concentrator is a hindered settling separator, using upward current water to create a column of stratified slurry in the tank. The heavier particles, which concentrate at the bottom of the tank, are discharged through the reject discharge valve. The smaller and lighter particles overflow the weir and are collected in the overflow launder with the overflow water.

Heavy smaller particles are recovered back into the settling chamber by reducing the upward flow velocity. This creates crowding in the upper settling chamber, which then forms what is known as ‘autogenous dense medium’.

The unit can be controlled via a plant PLC system or a remote Optima Concentrator control system.

The Optima Concentrator technology can be used as a separation module add-on to an existing coal or mineral preparation plant, to increase overall plant recovery and quality.
