Dowding, Reynard & Associates (DRA) will exhibit in Arequipa, Peru from the 15th -19th September at Extemin 2003 and at the International Mineral Processing Congress in Cape Town from the 29th September to 2nd October 2003.
During the last 18 months, the South African mineral plant design and engineering company, Dowding, Reynard and Associates (DRA) constructed seven platinum concentrator plants. Once again confirming their predominance in this area, DRA teams have worked on the Marula, Amandelbult, Marikana, EPC, K4, Messina and Mimosa projects.
In a further project for Anglo Platinum, Vhumbanani Projects, the joint venture company between DRA and Townshend van der Walt and Partners (TWP) was awarded the EPCM contract to manage Anglo’s new R800-million Twickenham Concentrator Plant. Scope of work includes ore receiving, materials handling, milling, flotation, classification, tailings lines, tailings dam, reagents, sampling and the raw water supply pipelines. The joint venture will pursue other Anglo Platinum Concentrator projects within the area.
Feasibility studies for Cluff Platinum’s Blue Ridge prospect and Aquarius Platinum’s 26-million ton Everest South orebody are underway. At Blue Ridge DRA is investigating the production of PGMs while assisting Aquarius Platinum to prepare the metallurgical and infrastructure sections as well as the overall feasibility study on its Everest South orebody.
A new R40 million project that entails reprocessing the No 4 and No 5 tailings dams at Blyvooruitzicht Gold Mine is also underway. The plant will process 240 000tpm and will include a carbon-in-leach circuit that will be separate from the carbon-in-pulp circuit used for ROM ore.
On site, 3100m up in the Highlands of Lesotho, a new 350tph DMS Plant for the Letseng Diamond project is well advanced. Ore commissioning is scheduled to commence in February 2004.
A ‘stand alone’ Micro DMS unit, the first to be sold in Canada, has been shipped to Mineral Services and will be installed in a purpose-built facility in Vancouver. The plant is due to be commissioned shortly and will be used to recover indicator minerals from exploration samples for a growing client base.
DRA Technical Services refurbished and upgraded a Koepe rock winder underground at Mopani Copper Mines in Zambia. This included replacing the winder drum and upgrading the braking system, a project which took about seven months to complete. The team is currently managing six other projects involving brake upgrades for the same client; they will be completed by October this year.
Managing projects from bankable feasibility studies for new mines to full commissioning has become a norm for DRA. According to managing director Brian Dowding, the company intends to build on recent project successes by opening up relationships with new clients throughout 2003.
