The flotation method involves mixing your crushed ore with water and then you add frothing agents in a single floatation machine. You then use a tube to release air into the floatation machine. This creates air bubbles to the bottom of the machine and this helps attach hydrophilic materials such as gold to the bubbles and thus float on the water.

A Poor Man's Method of Smelting Gold ... Connect a hair dryer to the open end of your metal pipe — use duct tape if necessary to close up any gaps. Once you complete your furnace, you can go about collecting your purification materials. Compounds for Oxidation.

To separate gold particles from a concentrate, concentrate is fed into the centrifuge through a pipe at the top of the machine in a slurry of around 60-75% water and 40-35% solids. The material collects in a vessel in the center of the machine where high speed rotation creates force that moves the material up the sides of the vessel’s walls.

Taking gold out of a sluice box, western North America, 1900s Using a sluice box to extract gold from placer deposits has long been a very common practice in prospecting and small-scale mining. A sluice box is essentially a man made channel with riffles set in the bottom.

The stereotypical grizzled gold-rush prospector panning for gold was searching for "placer gold", or gold deposited in a waterway. Placer mining takes a variety of forms, including panning, "sluice-boxing", hydraulic mining, and dredging. All of these techniques use gravity and water to separate the dense gold from the lighter sand and gravel.
