density of gold bearing rock Gold can be visible or invisible in quartz, and it is never evenly distributed in veins. Goldbearing veins have ore grades that rarely average as high as ounce per ton of gold (opt Au). Today, many gold mines produce ore at average grades. Gold Mining Mining Shares | Guide from BullionVault
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 oz. per ton, the wt. %m = X 10 4% dm = Thus if such an ore is to be sampled to oz. ( = 5 per cent error) at 20 mesh, the sample to be taken is
Surface Mining Surface mining is the primary source of gold and silver. It requires extensive blasting as well as rock, soil, and vegetation removal to reach load deposits. Ore is removed from the mine and transported to milling and beneficiating plants for concentrating the ore.
