This follows naturally from the preceding discussion. Mobile and highly soluble oils are easily dispersed in an extremely high state of subdivision, while viscous and slightly soluble oils are dispersed more slowly and to no such high degree. In pulp-body concentration the function of the oil is to coat the mineral particles.

dependent on concentration; i.e., it is not correct to assume that changes in concentration will make one frother perform like another. Bubble size in water (pulp) can be matched by changing concentration between 2 frother types (4) so that their relative concentrations to the CCC are the same, but gas hold-up and froth stability will be different.

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.

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.
