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 2040 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.

For instance, in a few situations, plants using gravity concentration for recovering gold, used magnetic separators to remove the high concentration of magnetite that was recovered with the gold, prior to further processing. Magnetic separation is generally a low cost method of recovery, unless high intensity separators are required.
The cupellation method is appropriate for separating gold from small amounts of ore. The refiner grinds the ore into a fine powder and mixes it with lead oxide, a flux made of sand or borax, and an organic reducing agent such as graphite or flour.
It was an extensive operation, the biggest in the San Juan Mountains, and employed the latest technologies available in 1929, including the new techniques of ball mill crushers, froth flotation of sulfide ores, and recovery of base metals as well as gold and silver.
Two other methods of gold refining are amalgamotion and smelting. In amalgamation, the gold ore is dissolved in solution and passed over mercurycovered plates to form a gold/mercury amalgam.
