Sulphur dioxide - Import export

Chemical appearance: Sodium Bisulfite 99% is a chemical compound created by bubbling sulfur dioxide through a solution of sodium carbonate in water. It appears solid white in color with a crystalline or granular texture. Sodium bisulfite also emits a slight sulphurous odor. It is not soluble in water and decomposes at its melting point i.e. 180C. Chemical application and strengths: Sodium bisulfite is a reliable leaching agent for cyanide detoxification in gold mining. Sodium bisulfite is used for detoxification of process leach residues along with air before discharging to the leach residue ponds. Sodium bisulfite serves as the ideal choice for leaching agent in gold mining despite the various doubts and confusion regarding suitable cyanide detoxification agents. Sodium bisulfite also finds applications for clearing oxidative corrosion in large piping systems.
