Sodium Metabisulfite: A Magical Chemical Substance In Mining
In the mining industry, sodium metabisulfite is a magical chemical substance. It may seem ordinary, but it plays an indispensable role in practical applications. So, what exactly is sodium metabisulfite? What role does it play in mining? Sodium metabisulfite, with the chemical formula Na2S2O5, is a white or yellow powder with an odor of sulfur dioxide. It is a strong reducing agent that can decompose into bisulfite ions and sulfate ions in water. Due to its unique chemical properties, sodium metabisulfite has been widely used in many fields, with its main use being as a precipitant and reducing agent in mining. In the mining process, useful components in the ore often coexist with some impurities. These impurities will have adverse effects on mining, therefore measures need to be taken to remove them. Sodium metabisulfite, as a strong reducing agent, can undergo oxidation-reduction reactions with various metal ions, thereby converting impurities into soluble sulfates or sulfides,
