Comminution circuits for gold ore processing - ScienceDirect

2005-1-1 · Hydrocyclones demonstrate a trait that is useful for gold mills – minerals with higher specific gravities having 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 Fig. 11). On a size-by-size basis, concentrations of up to 100 times can occur in cyclone underflow.
