Increase Dissolved Oxygen in Gold Leaching with Hydrogen Peroxide

Extensive measurements of the oxygen level in various gold leaching plants have shown that the oxygen concentration is often significantly below the saturation limit about 8 ppm . This results in poor extraction of precious metals. It is caused by the inefficient transfer of the gaseous oxygen through the phase barrier to the liquid phase.

The role of oxygen in thiosulphate leaching of gold

The role of oxygen in thiosulphate leaching of gold has been investigated in both pure gold and ore systems. The gold dissolution decreased in the presence of oxygen in the pure gold system. Air or oxygen bubbling caused higher consumption of thiosulphate and leaching passivation. Nitrogen bubbling largely increased gold dissolution and this

The role of oxygen in thiosulphate leaching of gold Request PDF

The role of oxygen in thiosulphate leaching of gold has been investigated in both pure gold and ore systems. The gold dissolution decreased in the presence of oxygen in the pure gold system.

Effect of Oxygen on Gold Leaching

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.

Cyanide Leaching Of Gold Mine Engineer.Com

Oxygen plays an important role in the leaching of gold in a cyanide solution also. It has been proven that the rate of dissolution of gold in cyanide solution is directly proportional to the amount of oxygen present. Normal water will have 89 ppm dissolved oxygen present in it.

The role of oxygen in thiosulphate leaching of gold

The role of oxygen in thiosulphate leaching of gold has been investigated in both pure gold and ore systems. The gold dissolution decreased in the presence of oxygen in the pure gold system. Air or oxygen bubbling caused higher consumption of thiosulphate and leaching passivation.

The role of oxygen in cyanide leaching of gold ore OneMine

quotThis paper is a brief overview of the role of oxygen in cyanide leaching of gold feeds e.g. ore concentrate . As the majority of gold occurs in the elemental state Au its oxidation is of vital importance for dissolution in the cyanide lixiviant.

The effects of dissolved oxygen and cyanide dosage on gold

This paper is a brief overview of the role of oxygen in cyanide leaching of gold feeds e.g. ore concentrate . As the majority of gold occurs in the elemental state Au its oxidation is of
