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 …

Gold room operations can be as simple as a single electrowinning cell and eluate tank, drying oven and smelting furnace. Or they can incorporate gravity-concentrate tabling, separate concentrate leaching, multiple electrowinning cells, cell-mud handling and filtration, and large-scale smelting operations. The complexity of the operation …
