Chemical appearance: The appearance of Sodium metabisulfite is either in the form of white crystals or as a powdered solid with a slight odor of sulfur. Inhalation could lead to toxic results and can cause serious damages to skin and tissue. Sodium metabisulfite is clearly soluble in water and forms a clear and colorless solution. Chemical application and strengths: The primary applications of Sodium metabisulfite are evident in the mining industry. It is used for controlling the depression of pyrites and sphalerite minerals. MBS is ideal for pH control for the froth flotation process, where it could control pyrite depression. Sodium Metabisulfite is also helpful in preventing flotation of sphalerite through copper activation with the availability of Tennantite/Covellite in the ore. In the case of pyrite flotation, the maximum iron/pyrite depression with the use of Sodium Metabisulfite is possible somewhere around the pH of 6. CAS Number:7681-57-4 HS Code:283210

Chemical appearance Dithiophosphate IBS or Sodium Diisobutyl Dithiophosphate has a yellowish and dark brown coloured appearance. It comes in a stable liquid form which has no strong smell. It has a PH level of 10 to 13. Chemical application and strength Dithiophosphate IBS or Sodium Diisobutyl Dithiophosphate is a very good collector of nickel, zinc minerals (activated), and copper ores. It is also used within gold harvesting plants because of its ability to increase harvest of precious metals. In the process of depressing iron sulphides, high levels of pH is needed which makes this floater the ideal one to use. Also great in the recovery process of refractory gold which is contained in sulphide matrices Compared to most collectors of sulphide, only a small amount of Dithiophosphate IBS is needed in the flotation process. This floater gives maximum value in recovering precious metals. CAS Number:53378-51-1 HS Code:292019

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

Chemical appearance Dithiophosphate BA or Ammonium Dibutyl Dithiophosphate has a white and pale greyish coloured appearance. It comes in a fine powder form which has no kind of odour. It has a PH level of 9. Chemical application and strength Dithiophosphate BA or Ammonium Dibutyl Dithiophosphate is a very good collector and flotation agent of nonferrous metallic minerals like copper, zinc sulfide (activated), silver, polymetallic ores, and lead. Its pH levels are ideal in the depressing process of iron pyrites. It has is a very strong collector compared to thiocarbamates and various secondary collectors. A good flotation agent and is quite selective within acidic environments. Dithiophosphate BA can be quite weak in collecting magnetizing pyrite and pyrite but is very selective It is a very good collector of galena and can enhance the separation of pyrite and galena.
