:: DMS copper ore separation project for Chemaf, DRC
Bateman Engineering has been contracted by Chemaf SPRL of Lubumbashi in the DRC to supply a modular plant to process 100 t/h of run-of-mine ore to produce a separated copper ore product by means of crushing, scrubbing, sizing and dense media separation (DMS) modules.
In approaching Bateman Engineering, Chemaf were seeking a solution to the problem of treating large quantities of ore through their conventional facilities. The Bateman Modular Plant will allow Chemaf to concentrate the feed product (prior to conventional processing) by means of DMS processing, a route other producers and their suppliers are also finding to be successful.
This plant, which will be erected and commissioned at Etoile on the outskirts of Lubumbashi, DRC in June 2008, thus represents a new approach to copper ore processing and a potentially vibrant new market for the DMS technique as it is not commonly employed in copper and cobalt oxide applications.
The plant consists of processing equipment, such as the vibrating equipment, jaw and cone crushers and tyre driven scrubbers, and comes complete with conventional belt conveyors linking the ore preparation with the modular DMS units. The two DMS modules each process 50 t/h ore which the client has selected, rather than a single larger module, to provide greater flexibility of operation.
The plant was manufactured near Johannesburg in South Africa. It was ordered ex-works on 24 July 2007 and was ready for dispatch on 28 February 2008. The DMS modules were fully assembled at the works, water tested and signed off by the client prior to dismantling and transport by road on the trailers to site. The peripheral equipment and commissioning spares packed in containers accompanied the consignment.
The approximately 3,500 km trip to the DRC site took typically about 15 days per consignment. The on-site assembly, commissioning and training of the operators, under supervision of an engineer from Bateman Engineering, requires a further 15 days. Commissioning is planned for mid 2008.
There has been increased activity lately in the southern region of the DRC to treat copper and cobalt oxide mineral rich ores present in the various concessions. One of the premier mining and mineral processing organisations in this region is Chemaf, which has been a producer of value-added copper and cobalt products in the DRC since August 2001. The modular plant ordered from Bateman Engineering will process ore from the Etoile deposit for which Chemaf is the sole licensee.
Bateman Modular Plants can be applied in prospecting, exploration, small-scale mining and mineral processing, and are designed to overcome the problems encountered in the erection and commissioning of processing facilities in remote and difficult locations. The design options are standardised, but flexible, and significantly reduce engineering and construction times and hence capital cost.
While the market for these plants has to date predominantly come from the diamond market, Bateman Engineering has also supplied plants to process coal, graphite, magnesite, andalusite, chromite, platinum and gold.
