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.
