According to the United States Geological Survey in 2016, about 5,726,000,000 troy ounces (178,100 t) of gold has been accounted for, of which 85% remains in active use. Since the 1880s, South Africa has been the source of a large proportion of the world's gold supply, and about 22% of the gold presently accounted is from So…
Just a refresher on specific gravity extracted from the Gold Facts page; Specific gravity is a measure of relative density - the ratio between the weight of a substance and weight of an equal volume of water at 4 degrees C (39 degrees F) - The Specific Gravity of Water at 4 Deg C is 1.0. The specific gravity of gold is around 19.3
This can be done by manipulating Eq. (1.1) which defines density. If we multiply both sides by V, we obtain (1) V × ρ = m V × V = m (2) m = V × ρ or mass = volume × density Taking the density of gold from Table 1.4, we can now calculate (3) Mass = m = V ρ = 428 cm 3 × 10 .32 g 1 cm 3 = 8.27 × 10 3 g = 8 .27 kg This is more than 18 lb of gold.

The average bulk density for float ore can be taken as 2.51.The recovery percentage for the 3nos. of iron ore samples varied from 58.50%, 63% and 61%, the average being the float ore recovery which is around 43%. Hematite (45%) is the abundant mineral. Martite and goethite occupied about 10% in the ore mineral.
