:: Phase 1 of Kalana is Complete
Dowding, Reynard and Associates (DRA) has completed Phase 1 of the re-opening of Kalana Mine 300km south of Bamako in Mali. This plant, much of which is housed in enclosed buildings, was originally built in 1985 with the assistance of the former Soviet Union. It operated until 1991 and at its peak produced 500kg of gold annually.
Phase 1 of the project involved the reconstruction of the plant using, at client’s request, as much of the original equipment as possible to recover gravity gold. Fabrication began in April 2003 and at that time the orders for long lead items including the cone crusher, Knelson concentrator, MCCs, screens and winder equipment were placed. Infrastructure, built by the Russians, was still in good condition. The new Knelson concentrator will recover gold from the ground ore. Coarse tails will be stockpiled for re-processing and fine tails will be pumped through to the thickener and on to the original tailings dam also for future re-processing.
Procurement and fabrication were completed in South Africa in August last year and shipped to site in Mali where DRA crews proceeded with construction. The plant was commissioned at the end of last year at a feed rate of 5000tpm through the existing mill.
It is envisaged that Phase 2 of the Kalana project will be the construction of a full carbon-in-leach (CIL) plant with a designed throughput of 200 000tpm of ROM ore. A feasibility study is being conducted by Avnel.
