Booysendal South tailings retreatment project, South Africa
This article has been supplied.
Name of the Project
Booysendal South tailings retreatment project.
Location
The Booysendal mining right straddles South Africa’s Limpopo and Mpumalanga provinces.
Client
Northam Platinum.
Project Description
The project entails the hydromining and reprocessing of the Booysendal South tailings storage facility (TSF) to extract 1.3-million tonnes of chrome concentrate from 8.7-million tonnes of tailings, from which platinum-group metals (PGMs) will also be extracted. Tailings from this project will be placed back underground in the old Everest workings to reduce environmental impact.
The tailings have a mineral content of about 18% chrome and 0.7 g to 0.8 g of PGMs a tonne.
The project will be undertaken in two phases – chrome will be extracted first and tailings returned to the storage facility before being processed for a second time to extract PGMs.
Apart from the compelling economics of this project, a key objective is to ensure that the concentrator is fully commissioned and optimised ahead of the run-of-mine feed from the Booysendal South mining project.
Potential Job Creation
