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.Uranium Mining and Extraction from Ore,[2,5] Fig. 3 shows a schematic of the in-situ leaching process, in which the leaching solution is pumped into the ore zone containing the uranium ore. The leaching solution is pumped back up into a plant for further processing.
