Officials at minerals process and project management company MDM Engineering Ltd. have announced that AngloGold Ashanti Ltd. has awarded them completion and commissioning contracts for their MWS uranium plant in Stilfontein, South Africa.

MDM officials said they have a long history with the MWS project, having commenced work on Phase 1B in Q1 2008, which witnessed a 50% project throughput increase from 650,000 metric tons per month (mt/m) to 1.283 million mt/m, treating the reclaimed tailings for the recovery of both gold and uranium.

The Phase 2 module was completed in 2011, and the plant treated an additional 650,000 mt/m of gold reclaimed tailings. Phase 2 also included a reclamation station pumping the material 12 km to a carbon in leach and elution plant, as well as all adjoining infrastructure. In all, MDM laid 72 km of pipeline for Phase 1B and Phase 2.
