Tschudi Copper Project, Namibia
Ore is hauled from the pit and blended using the finger pile system. The run-of-mine ore passes through a three-stage crushing unit featuring a primary jaw crusher, a secondary gyratory crusher and two tertiary gyratory crushers. The crushed ore is then taken to the agglomeration plant, where sulphuric acid and raffinate are added.
