DMS (Dense Media Separation) Plant

Heavy ferrosilicon material mixed in water creates a carefully controlled slurry that represents the dense media. This dense media continuously circulates through a series of pumps and, once combined with a sample of crushed kimberlite, passes through screens and vortexes that allow the heavy minerals (including diamonds) to settle through the slurry and be collected for further analysis. Lighter grains are kept in suspension and ‘floated off' for more work or disposal

* Purchased from Dowding, Reynard and Associates of South Africa, the Micro Plus DMS is a mobile and compact plant designed for either the mini-bulk testing of kimberlites or the processing of individual small samples.

* Sensitive to heavy mineral grains as small as 0.3 mm in diameter, making it useful for analyzing small rock samples or even sediment samples for diamonds or diamond indicator minerals.

* Can run samples from 2kg up to 100 tonnes.

* Currently about 15 similar models in operation throughout the world.

* Equipped with a water filtration and recirculation system for minimum environmental impact.

DMS

* Maximum rated speed of 1.5 tonnes/hour of sample material using a lower cut-off of 0.8 mm grains; rated at 300 kg/hour with a lower cut off of 0.3 mm grain diameter. This lower threshold is very useful for diamond distribution curve information.

* Adjustable crush size and a customized flow sheet allows for careful treatment of sample material and avoids fracturing of larger stones or loss of smaller stones.
