Reclamation & Deposition
Witwatersrand Basin
After the solid tailing material of the current deposition sites in the Witwatersrand is converted into slurry, it is filtered and re-processed by the existing processing plants to take out the remaining gold and uranium. The left-over slurry is then transported through pipes to the centralized tailing facility. At the facility, the material is converted into ‘cake’ by a process of dewatering. The now dry material is transported to the final deposition site, where it is stacked by so-called ‘spreaders’.
