— If you encounter a large amount of heavy black sand, stage panning can be a useful technique. Divide your material into smaller portions and pan each portion separately. This allows for more focused gold recovery and facilitates better separation from the black sand. Using a magnet to remove magnetic black sands
The black sand separation system. This is our black sand separation system. When concentrate contains some gold and we do not want to recover the small gold, but need some black sand, we are using the classic magnetic separation from one bowl to other bowl. The concentrate is first dried on the stove, then black sand is removed for our …

— While the ultrasonic separation may work well on a small unit with dry sand, I am wondering if it is practical to scale this idea up to a unit with a hopper of 20-40 litres capacity. Also, as it is not practical, at the claim site, to dry sand in large quantities, I wonder how feeding damp sand into such a machine would effect its operation.
Both these tools are covered in much more detail in my guide to separating gold from black sand. Important Tip: Use Jet Dry or Dishwashing Soap. The surface tension of the water will sometimes act to lift up tiny gold particles so that they escape your recovery device together with the lighter materials. To prevent this, you can just break the ...

— The mineral composition of the gold ore, including the type of gold minerals and associated gangue minerals, can significantly affect the flotation process. Some minerals may be more easily floated, while others …
— Or pan the gold manually in water to separate gold from the gravel and sand in a stream. Refine the gold you have extracted and separated. Use Miller and Wohlwill processes, which process gold chloride by subjecting it to an electric current; this separates gold from impurities and attaches it to the anodes generating the current.
— The density of salt is 2.16 g/cm³ while the density of sand is 2.65 g/cm³. In other words, sand is slightly heavier than salt. If you shake a pan of salt and sand, the salt will eventually rise to the top. A similar method is used to pan for gold, since gold has a higher density than most other substances and sinks in a mixture.
— It features a specialized table surface that aids in the concentration and separation of fine gold particles. Aside from the Miller Table, the Black Magic is another equipment that can be utilized for fine gold recovery. This equipment is specifically designed to efficiently separate fine gold from black sands and concentrates.
