Effect of Oxygen on Gold LeachingGold Recovery - Silver Recovery - Platinum Recovery

In simplified terms, the Effect of Oxygen on Gold Leaching can be summarized in saying: The dissolution rate of gold in alkaline cyanide solutions under atmospheric conditions, and at practical cyanide levels, is directly proportional to the dissolved oxygen concentration The rate of dissolution of gold in alkaline cyanide solution is dependent on a number of factors, principally the solution .Our special leaching system is also designed with the hobbyist or do it yourselfer in mind, so again, out of the several types of leaching methods, it is one of the safest, requiring only common household supplies, and is based on practical information that will allow almost anyone to extract gold from items such as, plated pc boards, gold.
