Gold is one of the heaviest minerals. When pure, it has a specific gravity of 19.3. Due to its weight, it can be panned because the Gold sinks to the bottom. In addition, it can be easily separated from other substances due to the weight differences. Gold is also the most malleable and ductile substance known.
To explain that in other words, the specific gravity of gold is 19.3 which means the weight of gold is 19.3 times that of an equivalent volume of water (at 4 degrees C). If water weight is 1 gram per ml then Gold at an SG of 19.3 is 19.3 times as dense as water or 19.3 grams
Jan 23, 2020 The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isnt as complex as you may think because waters density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).
Refractory gold ores, however, require rather sophisticated recovery techniques. Different ways of gold concentration (p15). 1.1 Gravity concentration Gravity concentration is the oldest technique for gold recovery. It makes use of the high specific gravity of gold that amounts
