Advanced control of gold ore grinding plants in South Africa
The grind of the final product in this area of South Africa has a large influence on the overall gold recovery. The closer the maximum ore particle size is to the maximum grain size of the valuable material, the more efficient the extraction will be (Stanley, 1987).In the case of these ores, the average grain size of the gold is 75. μm.. Mponeng has a steep "grind-recovery" …
