FIG. 8.9 The stages of panning a concentrate from sediment. Often the sediment is sieved to ≤2 mm although
this may eliminate any large nugget. Note the importance of mixing the sediment well so that the heavy
minerals stay at the bottom of the pan. For an experienced panner the operation will take about 20 minutes.
