Xanthates are a group of chemicals typically used in sulphide flotation in mining applications. Common xanthate products are sodium ethyl xanthate (SEX), sodium isopropyl xanthate (SIPX), sodium isobutyl xanthate (SIBX) and potassium amyl xanthate (PAX).
•Isopropyl xanthic anhydride, iPrXA, was the final product of the reactions of potassium isopropyl xanthate and ethyl chloroformate in an ethanol-water mixture. This reaction generated an S-ethoxycarbonyl O-isopropyl dithiocarbonate intermediate first, and then it reacted further with xanthate to give iPrXA2,3.

Potassium Amyl Xanthate: Symptoms of potassium poisoning may occur. These include slow heartbeat, accelerated breathing, muscle weakness and, in severe cases, paralysis. Vapours of the decomposition products of Xanthates (Carbon Bisulphide) can cause severe disturbances of mood and behaviour, including excitation, anger and violent dreams. High

Potassium isobutyl xanthate 90% is also a stronger collector in the flotation of various nonferrous metallic sulfide ores. Isobutyl potassium xanthate is mainly used in floating copper, lead, zinc sulfide ores, etc. Isobutyl potassium xanthate has displayed especially effective in the flotation of copper ores and of pyrites in natural circuits.

Flottec SIPX/Flomin C3330/AERO 343. Sodium isopropyl xanthate (SIPX) and sodium isobutyl xanthate (SIBX) are typically used when the collector needs to be stronger than SEX without compromising too much on selectivity, for instance in some copper-gold, copper-zinc and nickel operations.

The potassium amyl xanthate was allowed to burn under controlled conditions. A 500 metre exclusion zone was established by evacuating about 100 homes in the downwind direction. The cause of the spontaneous ignition of this batch of potassium amyl xanthate is being investigated by the manufacturers.
Potassium amyl xanthate is widely used in the flotation processes of nonferrous metallic minerals where a strong but a non-selective collector is desired. Potassium amyl xanthate powder is a good collector for the flotation of oxide minerals, eg.: oxidized sulfide, copper and lead ores.
Xanthates can be obtained by reacting an alcohol with carbon disulphide and an alkali such as sodium hydroxide or potassium hydroxide. The alcohols employed are not unique. They can form ethyl, butyl (isobutyl, normal butyl, secondary butyl), propyl (isopropyl, normal propyl) and amyl (isoamyl, normal amyl, secondary amyl) xanthates, in dry forms, such as powder, granules, pellets, tablets or flakes.
The freshly prepared xanthate solution will contain low levels of carbon disulphide. This is formed by decomposition of some xanthate molecules during dissolution of dry PAX. During storage of xanthate solution there will be further decomposition of xanthate molecules producing yielding increasing levels of carbon disulphide in the solution.
the xanthate is consumed in the process. Different xanthates have different strengths. The strength of xanthate as a collector is based on the alcohol chain attached to the xanthate molecule with ethyl being the weakest and amyl being the strongest. Potassium ethyl xanthate is very selective in nature and cost effective.
Our top selling range is Sodium Isopropyl Xanthate and Potassium Amyl Xanthate. Used world wide Copper flotation circuits Democratic Republic of the Congo, Zambia, Mexico, Chile and Canada. China is a world centre for collectors accounting for more than 50% of world manufacturing capacity for sulphide collectors.
Often the alkoxide is generated in situ by treating the alcohol with sodium or potassium hydroxide: ROH + CS 2 + KOH → ROCS 2 K + H 2 O. For example, sodium ethoxide gives sodium ethyl xanthate. Many alcohols can be used in this reaction. Technical grade xanthate salts are usually of 90–95% purity.
This study compared the effects of using potassium amyl xanthate (PAX), isopropyl ethyl thionocarbamate (IPETC), sodium isobutyl xanthate (SIBX) and their mixtures in the froth flotation of a pentlandite ore. In the mixtures of PAX or SIBX with IPETC, the xanthate accounted for 95.5 mol% and for the PAX and SIBX mixture a 50:50 mixture was used.
The alkoxide is often generated in situ from potassium hydroxide: CH 3 CH 2 OH + CS 2 + KOH → CH 3 CH 2 OCS 2 K + H 2 O. Potassium ethyl xanthate is a pale yellow powder that is stable at high pH but rapidly hydrolyses at pH <9 at 25 °C. Unlike the sodium derivative, potassium xanthate crystallizes as the anhydrous salt and is nonhygroscopic.
The four common xanthate collectors are sodium isobutyl, sodium ethyl, sodium normal propyl and potassium amyl xanthate . In this research, the optimal dosage of SIBX collector for the froth flotation of Palabora ore was determined to ensure the efficient froth flotation of the ore with this collector.
The methanol, ethanol, isopropyl alcohol, n-butanol, ethylene glycol, CS 2, KOH and zinc chloride (ZnCl 2) were analytical grade and used as supplied. Preparation of Zinc Alkyl Xanthate Potassium methyl, ethyl, isopropyl, butyl, and ethylene glycol xanthates were prepared by mixing equimolar amounts of the corresponding alcohol, KOH, and CS 2
