How to Sample Gold Ore - Mineral Processing Metallurgy

dm = density of the mineral m. It is on gold ores carrying relatively coarse gold that the real problem arises, because the wt. %m is low and the dm is high. In ore assaying 0.1 oz. per ton, the wt. %m =4.2 X 10 -4% dm = 10.3. 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
