How to Sample Gold Ore
Thus if such an ore is to be sampled to 0.005 oz. ( = 5 per cent error) at 20 mesh, the sample to be taken is. This assumes the gold to be free and occurring in grains up to 20 mesh in size. For a 500-gram sample of this ore to be representative to a 5 per cent error, the ore would have to be crushed to 0.833/∛160 = 0.156 mm = 100 mesh approx.
