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 CAS Number:143-33-9 HS Code:283711

Chemical appearance Dithiophosphate 25s or Hydrogen Phosphorodithioate has an appearance of a deep brown or almost black liquid. Some may classify it as a vandyck brown oily liquid and it has a density of 1.17 – 1.20. It has a PH value of 10 – 13 and a mineral substances percentage of 46 – 49. Chemical application and strength Dithiophosphate 25s or Hydrogen Phosphorodithioate is known to be a good flotation collector of copper, silver sulfide, zinc sulfide (activated), and lead ores. It can somewhat be dissolved in water. Also, it can be directly poured into ball mills and surge tanks. Hydrogen Phosphorodithioate is used mainly in the separation flotation process of ores like lead and zinc. Because of its properties it should not be subjected to intense heat like fire or extreme sunlight. Proper packaging must be observed. It is weak in collecting sulfide minerals and pyrite when in alkaline medium. It also is selective in collecting ores. CAS Number:61792-48-1 HS Code:292019
