— Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.

The ball mill is for grinding material to small fine powder because flotation process needs 200mesh material, need work together with a spiral classifier to reach 200mesh output from the overflow of classifier, the underflow coarse particles will go back to ball mill grind again, to be closed-circuit.

 — Counter-current leaching. leaching efficiency can be enhanced by the application of Le Chatelier's principle. In summary, the lower the concentration of gold in solution, the greater the driving force for gold dissolution to occur, although in a mass transport controlled reaction it is debatable what role this plays in gold leaching.
