    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
