Leaching often gold is the process of extracting a soluble constituent from a solid by means of a solvent In extractive metallurgy of gold it is the process of dissolving a certain mineral or minerals from an ore or a concentrate or dissolving certain constituents from materials such as a calcines mattes scrap alloys anodic slimes etc to achieve either one or two purposes

What is the Effect of Aeration on Gold and Silver Leaching Another of the prime requisites of successful cyanidation is free oxygen Pure oxygen is too expensive to use instead atmospheric air is the customary source of the required oxygen gas Some interesting experiments have been conducted using Ozone but the practice has not been adopted commercially on account of the cost in the gold

CSIRO Australia has developed a thiosulfatebased reagent system for gold leaching that has excellent stability and shown broad applicability in the laboratory compared to the thiosulfate system commercially implemented by Barrick to treat double refractory gold ore following pressure oxidation at its Goldstrike Mine in Nevada USA
