How to Sample Gold Ore - 911 Metallurgist

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. 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 =

Gold processing - Mining and concentrating Britannica

Amalgamation is accomplished by passing a slurry of ore over copper plates coated with mercury, by mixing a slurry of ore and mercury in a cylindrical or conical vessel called an amalgam barrel, or by grinding the ore in a ball, rod, or pebble mill to free the gold from the mineral matrix and then adding mercury to the mill and continuing grinding until the gold has dissolved in the mercury. The denser amalgam is then separated from the now barren ore

Common gold grades are in the same magnitude as about 5 g/t, or 0.000005% gold content by weight. This means that upgrading the concentration by a factor of 3000 to 4000 is commonly required to achieve commercial ore (Marsden House, 2009). In order to make extraction possible, significant comminution is required as well as the utilization of chemicals such as cyanide for leaching in the ...
