The longer the hydrocarbon chain on the xanthate molecule, the stronger the hydrophobicity is likely to be. Hence, sodium ethyl xanthate (SEX) with two carbon molecules in the chain, is the weakest xanthate and is used where selectivity is most important. It is applicable to the flotation of minerals that are already activated or partially hydrophobic and float easily, such as activated zinc, nickel, and lead.
XANTHATES IN MINING
Xanthates have been the workhorse of sulfide mineral flotation since the 1920s (Harris 1989), and they represent the largest volume of any sulfide mineral collector. Xanthate collectors are salts consisting of a non-polar hydrocarbon group, which provides the hydrophobicity to a sulphide mineral, pointing outward from the mineral to the solution, and a polar group that adsorbs onto the sulphide mineral surface.
PRODUCTION OF XANTHATES
RAW MATERIALS: Carbon Disulfide, Caustic Soda (Sodium Hydroxide), or Potash (Potassium Hydroxide) and determined alcohol, which provides it with collecting properties in flotation processes of metallic and polymetallic minerals.
WHAT IS THE QUALITY OF YOUR XANTHATE?
The production of pure xanthates requires pure raw materials and then the reaction must also be driven to completion. This requires sophisticated process design and control of the manufacturing process which, in turn, influences the price and metallurgical efficiency of the product.

It is a colourless liquid that when undiluted is also called glacial acetic acid. It has a distinctive sour taste and pungent smell.
Acetic acid uses: Additive in industrial explosives in Mining.
Other uses include use of acetic acid in the production of vinyl acetate monomer, acetic anhydride and ester production.
Chemical gassing agents -In the case of emulsion explosives, using Acetic acid can accelerate the gassing process. The chemically gassed emulsions may take 40 – 50 minutes for completion of gassing within the blast holes, particularly when the emulsion is colder.
In cases where acetic acid is used, it is added to the emulsion prior to gassing, the desired amount of acid is mixed in the emulsion, before adding the gasser.
A gassing solution comprising sodium nitrite in water together with the selected enol compound and acetic acid is introduced into the emulsion explosive at the blast hole by entraining the gassing solution into a stream of the emulsion explosive using pumps.
The solution pH is an important parameter in the gassing of emulsion explosives due to the high cost associated with acid addition therefore a pH value should preferably be maintained at 4.1 or below.

4.Environmental impact
- Acetic acid biodegrades readily under both aerobic and anaerobic conditions.
- Acetic acid does not absorb light with wavelengths >290 nm(4), and is not expected to be susceptible to direct photolysis by sunlight(SRC).
- Incase of spillage neutralize spill with soda ash or lime.
