Overall design and construction of the process plant

DRA Global was awarded the overall design and construction of the process plant at Dwarsrivier. This chromite plant in Mpumulanga consists of run-of-mine handling and stockpiling with crushing and screening to definitive top sizes.

The plus 6mm feed is separated by dense medium drum and cyclone separation. The minus 6mm fine material is milled to liberate silica from the relatively small crystal structures and to ensure the adequate liberation of chromite. This milled product is treated in a complex spiral circuit to produce different grades of fine chromite.
