In general, froth floatation is a technique that easily separates hydrophobic materials such as gold from hydrophilic materials [1]. The hydrophobicity of gold and the ability of ferrous sulfide to increase the surface tension of water create an opportunity for an efficient method for the extraction of gold dust [1].
Mercury. We used mercury to get the gold out of the powdered rock. Gold, like most minerals, can be 'dissolved' in mercury to form what's called an amalgam. An amalgam is a physical mixture, a type of alloy. This is a comparatively straightforward way of separating the gold from the rock, as the rock remains untouched by the mercury.
Flour Gold Recovery. Flour gold can be defined as ultra-fine gold found in a low micron size fraction, often smaller than 74 microns or 200 mesh.

When it comes to separation, the key lies in exploiting the contrasting properties of gold and sand. Gold's density allows it to sink to the bottom of a pan or sluice box, while sand tends to remain suspended or float. Now that we have a basic understanding, let's ensure your safety before proceeding further. Safety Precautions

Pour the acid-and-bleach mixture into the plastic bowl with the ore grains and stir. Allow four hours for the gold to dissolve, stirring every 20 minutes. The chlorine reacts with the gold inside the ore to form gold chloride. Filter the ore and bleach solution to remove all the impurities, such as soil and rock fragments.
Usually, this would be along the banks of a river or stream, where the water is at least 6in (15cm) deep. However, there is one more factor for you to keep into consideration: the path the gold follows. Indeed, as the particles travel along the river or stream, the particles of gold will follow a specific way.
