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.

Chemical appearance: Sodium cyanide is found either in the white crystalline form or in the form of granular powder. It is also water-soluble and forms a clear and colorless aqueous solution. Chemical application and strengths: The most important application of sodium cyanide is evident in the extraction of gold. The use of sodium cyanide is still the best method for mining gold. Sodium cyanide is a common agent in the leaching process for the majority of gold extraction operations. The primary reason for the use of Sodium cyanide in the extraction of gold is the higher affinity of gold towards cyanide. Sodium cyanide separates gold through oxidizing it and dissolving gold in the presence of oxygen and water. The most important strengths of sodium cyanide in the mining of precious metals are reflected in its cost-effectiveness, higher availability, and better processing

Chemical appearance: Activated Carbon is the general name assigned for a group of porous carbons. The appearance of activated Carbon depends considerably on the process used for the activation of Carbon. The product is typically charcoal black with varying mesh sizes. Chemical application and strength: The primary application of granular activated carbon mesh is evident in the process of cyanidation. Cyanidation is the metallurgical process for mining gold from ore that contains cyanide. The use of physical activation involves hot gases either through carbonization or oxidation. Granular activated Carbon has an appearance just like the name indicates with the higher surface area for adsorption. Activated Carbon is produced from sources enriched in Carbon. Therefore, the surface structure of activated Carbon is very porous, and it also has a vast surface area.
