The processing of gold ores has traditionally made use of conventional crushing and grinding circuits. In each case where gold is formed either as coarse native particles or in coarse grained sulphides, it is recovered by gravimetry concentration in the in the comminution circuit in addition to recovery of finer values by leaching. Jigs are the ...

Mineral processing equipment should be large-scale. When the process flow is the same, 2-3 series are suitable for the large concentrators, one series for simple or mature processes, and 1-2 series for the medium and small concentrators. Flowchart comparison can determine the specific series after flowchart comparison.
