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.

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.

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.

Chemical appearance
Isopropyl Ethyl Thionocarbamate or O – Isopropyl – N – Ethyl Thionocarbamate has a type of dark brown or amber colour and comes in a liquid form with an oily consistency. It is partially dissolvable in water and has a density of 990 – 1004 kg/m3.
Chemical application and strength
Isopropyl Ethyl Thionocarbamate or O – Isopropyl – N – Ethyl Thionocarbamate is another strong type of collector which has characteristics of having strong collection in the flotation process of various nonferrous metallic sulfides.
Partially soluble in water but is highly soluble in benzene, petroleum ether, alcohol, ethyl ether, and many more.
Has weak collective power with regards to pyrites, but is very selective in the flotation process of various sulfide ores.
It should be placed in an environment away from exposure to water and extreme heat from fire and sunlight. It should always be placed upright and never upside down
Compared to xanthates it has a better frothing ability.
CAS Number:141 – 98 – 0
HS Code:293020
Potassium Butyl Xanthate is a reagent that plays a pivotal role in modern mining and metallurgy.
Flotation Process Facilitator: Potassium Butyl Xanthate is an indispensable ally in the flotation process, a cornerstone of mineral extraction. Flotation involves separating desired minerals from their ores.
Selective Adhesion: When introduced to a slurry of finely ground ore and water, Potassium Butyl Xanthate selectively adheres to sulfide minerals present in the mixture. These minerals, often hosting valuable elements like copper or lead, exhibit a unique affinity for the xanthate.
Bubble Attachment: Air bubbles are introduced into the slurry. The hydrophobic mineral surfaces coated with Potassium Butyl Xanthate collectors readily attach to the bubbles, effectively making them float to the surface.
Rising to the Top: The mineral-laden bubbles rise to the surface of the flotation cell, forming a froth layer.
