A history of gravity separation at Richards Bay Minerals
Gravity separation techniques have been in use in the mineral sands industry for decades; from the Reichert cone to tables, Wright sluices and the Kelsey Jig, all attempting that elusive perfect gravity separation. Just as the gravity separation industry evolved, Richards Bay Minerals also evolved in their use and approach to gravity separation.
