Heap Leach Stacking and Agglomeration Project for gold mine in Burkina Faso
A major gold operation in Burkina Faso required a heap leach stacking system that could handle operating in challenging conditions, including temperatures of up to 50°C. TNT designed and supplied an innovative solution, which required expansion two years after its original commissioning. The result was a highly efficient system capable of processing 7.5 million tonnes of ore per year and designed for 4-6 stacking lifts.
