Six flotation tests were conducted using the copper–gold ore and its mixtures with quartz, clay minerals and gypsum. Fig. 1 shows the mass recovery as a function of water recovery from these tests. As can be seen, flotation of the ore or baseline resulted in a 5% mass recovery and 31% water recovery at the completion of flotation.

The ground up ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold's hydrophobicity. This mixture is placed into a tank or flotation cell filled with distilled water.
Semi-industrial tests were conducted to investigate the feasibility and efficiency of a combined column and mechanical flotation cell process for the beneficiation of Sanshandao low-grade gold ore. The results showed that the performance of the combined flotation process of the cyclonic-static microbubble flotation column …
However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold's hydrophobicity.
