Our Projects
Diamond Processing Experts in South Africa
We’re proud to offer bulk diamond processing and caustic fusion to the diamond industry. Here’s a look at some of our successful projects as process consultants and the sole supplier of caustic fusion in South Africa.
Kareevlei Mine Turn-Around
PMC was subcontracted by Minexec to audit the processing sections of the Kareevlei Diamond Mine as part of a turn-around attempt of a struggling mine and processing plant.
UARI 50tph DMS
PMC received an order to supply a 50tph DMS to the UARI Mine in Angola. The DMS is designed as a non-mobile unit erected on a concrete base with plinths.
Caustic Fusion Facility
Caustic Fusion Facility for Angolan Geological Society
The Geological Society of Angola approached PMC’s sister company MME to supply a 40kg per day Caustic Fusion Facility.
Klipspringer Plant Refurbishment
The Klipspringer Mine processing plant was restarted as part of a bulk sample program and also to treat the coarse tailings dump.
Sample Plant Refurbishment
De Beers Exploration Services was contracted by Jwaneng Mine to test the Jwaneng resource extension samples known as Jwaneng Deeps.
Letlhakane Sample Plant
PMC was contracted by Tsodilo Resources to refurbish the old Debot (De Beers Botswana Exploration) sampling plant in Letlhakane, Botswana.
ARMA Double Trommel Screen
PMC supplied ARMA with a 50tph double trommel screen, screening at 0.5mm and 5mm, to treat old tailings. This trommel screen contributed to significant additional profit for ARMA.
Mooikloof Bulk Sampling
The client sent drill core samples from various holes from the Mooikloof concession in Limpopo to recover macro diamonds from the drill core samples. PMC has access to all the equipment to crush and screen the drill core samples and a 150mm DMS to do the primary separation.
Finsch Fine Diamond Sampling
Petra’s Finsch Diamond Mine sent 10 tons of degrit material to test for the presence of diamonds in the degrit material. The material was treated through a 150mm DMS at low feed rates. The DMS concentrate was treated over a grease table and the grease concentrate was fused with caustic to recover all the diamonds. The results were very encouraging.
