:: New Diamond-Recovery Plant Installed at Miba in DRC

NLK2, the 400 t/h kimberlite-processing plant ordered by Miba, has been successfully commissioned by Bateman in Mbuji Mayi in the Democratic Republic of the Congo (DRC). The commissioning was completed in two-and-a-half weeks by a Bateman team of process, equipment and electrical engineers.

The plant comprises a front-end ore-preparation circuit, a re-crushing circuit and two new-generation twin-stream mega 200 t/h dense-media separation (DMS) modules. The entire plant was fabricated in various workshops in the Reef area of South Africa. The mega DMS modules were pre-assembled and tested in the works prior to dismantling and packing for transport to the DRC.

The complete plant was transported in 90 DZ rail wagons from the Kazerne rail siding in South Africa, through Zimbabwe and Zambia, to the Mwene-Ditu mine siding in the DRC, some 100 km from the Miba mine at Mbuji Mayi. Some 800 t were railed to the mine siding, with the mega DMS modules alone weighing 130 t.

This is the second plant of this type supplied to Miba. The first DMS unit for NLK1, supplied in 1998, was a single-stream DMS unit with a capacity of 150 t/h.
