Gold Fields South Deep Gold Mine
Step 1: Milling. When ore enters the plant from underground it first needs to be milled to reduce its size so that the gold is liberated from the host rock. South Deep's milling circuit consists of a single-stage semi-autogenous grinding mill (SAG) and a pebble crusher for primary milling, followed by secondary milling using two overflow ball ...

Refractory Gold Ore Treatment Methods
The clear solution drawn off from an agitator is run to two settling vats 16 ft. 6 in. in diameter by 4 ft. deep. The solution stands in settlers until any cloudiness has settled. It is then run through a sand filter and then to the zinc boxes. An 80 per cent gold recovery was made by the method of treatment described.

Comminution Circuits for Gold Ore Processing
Hydrocyclones demonstrate a trait that is useful for gold mills—minerals with higher specific gravities have a progressively finer cut-size (whether this is desired or not). In plants with free-milling gold, this leads to gold concentrating in the milling circuits (see Figure 17.13). On a size-by-size basis, concentrations of up to 100 times ...
