PRINCE ALBERT, Saskatchewan The 10-tonne/hour dense media separation (DMS) plant at the Star diamond project is complete, and commissioning will begin as soon as it is winterized, says 100%-owner SHORE GOLD of Saskatoon.
The plant was supplied by Batemen Engineering of South Africa. It includes jaw and cone crushing, scrubbing, screening, and DMS of heavy mineral concentrate. These steps will be followed by x-ray sorting and diamond recovery on a grease table.
One of the largest in the world, the Star kimberlite is believed to total 500 million tonnes. Development for underground mining is proceeding. The concrete-lined shaft is based below the sediment-kimberlite interface and is below the freeze-wall. The shaft will bottom out at 250 metres.
According to Shore, the aim of the Star project is to recover and process 25,000 tonnes of kimberlite in order to produce a macrodiamond parcel of some 3,000 carats. This diamond parcel will be used for stone valuation purposes.
