Tailings Dam 7
Fraser Alexander™s tailings operations in Zambia are based in Chingola, where various hydro-sluicing projects are operated for Konkola Copper Mine. Initially, the mine only used the TD2 tailings dam as a deposition facility for its copper tailings, while the runoff water ran into the pollution control dam (PCD). Since the dam was proving to be inadequate to handle the tailings volumes, further dams were built.
Fraser Alexander was asked to put together a plan to re-mine the TD7 tailings dam, which was implemented within three weeks, an aspect which gave us the edge over our competitors with regard to delivery time. The high-pressure water pumps and slurry pumps were installed within three days.
Currently 10 000 tons of tailings are pumped from TD7 per day, amounting to 300 000 tons per month.
A new approach was suggested for the removal of slime from the PCD, which was not producing the required volumes. The installation of a barge with a new pump and the use of the latest hydro-sluicing equipment have improved the recovery of slime from the PCD to such an extent that the dam has surpassed its target beyond expectation.
Based on Fraser Alexander’s successes with the Konkola tailings dams, the mine requested that the company establish re-mining solutions for TD3a and 3b. All the planning has been completed to start operations in February 2009. The last phase will involve implementation of the TD5 re-mining solution. The next step is the implementation of an overall maintenance plan for the entire tailings site.
The Konkola project has been characterised by exceptional delivery times, good working relationships and transparency in all communications. We believe that our approach has proven that Fraser Alexander has the cutting edge expertise to provide an innovative solution to any tailings challenge.
