Sodium metabisulfite, as a common chemical agent, plays an important role in the flotation process of gold mines.

1. Properties of sodium metabisulfite

Sodium metabisulfite (Na2S2O5) is a new type of highly efficient precipitant with a strong pungent odor, with a chemical formula of 190.11. It is a white crystalline powder that is insoluble in water and easily soluble in acid.

2. Application of sodium metabisulfite in gold mines

Sodium metabisulfite is mainly used as a precipitant and oxidant in the flotation process of gold mines. When added to the flotation solution, sodium metabisulfite can react with the surface of gold minerals, forming hydrophilic sulfides and sulfite ions on the surface of gold minerals, thereby achieving the separation of gold.

3. Mechanism of action of sodium metabisulfite

The mechanism of action of sodium metabisulfite in gold mines mainly includes the following two aspects:

Oxidation-reduction effect: Sodium metabisulfite has strong reducibility and can effectively reduce trivalent iron on the surface of gold minerals to divalent iron, making it easier to form complexes with coordination agents such as cyanide, thereby achieving adsorption and separation of gold.

4. Precipitation effect: The sulfite ion generated by the reaction between sodium metabisulfite and the surface of gold minerals can effectively inhibit the complexation reaction of divalent iron and cyanide coordination agents on the surface of gold minerals, making it easier for the surface of gold minerals to form a hydrophobic oil film with the collector, ultimately achieving flotation separation of gold.

Sodium metabisulfite, as a new and efficient precipitant and oxidant, plays an important role in the flotation process of gold mines. By deeply understanding its properties, mechanism of action, and usage methods, the beneficiation efficiency and concentrate grade of gold ore can be more effectively improved, and the maximum utilization of gold ore resources can be achieved.
