Potassium ethyl xanthate (CAS 140-90-9) is the potassium salt of ethyl xanthic acid, an O-ethyl dithiocarbonate. It is used as a collector in the froth flotation of sulfide minerals and as a reagent in analytical chemistry. It is supplied to mineral-processing operations.
Frequently Asked Questions
What is potassium ethyl xanthate used for?
Potassium ethyl xanthate (PEX, CAS 140-90-9) is used primarily as a collector reagent in the froth flotation of sulfide minerals, enabling selective recovery and concentration of ores. It also serves as a reagent in analytical chemistry. It is supplied directly to mineral-processing operations.
Is potassium ethyl xanthate a salt?
Yes. It is the potassium salt of ethyl xanthic acid — an O-ethyl dithiocarbonate. It is also referred to as potassium O-ethyl dithiocarbonate.
Is potassium ethyl xanthate soluble in water?
Yes, potassium ethyl xanthate is water-soluble, which is why it is dosed as an aqueous solution in flotation circuits. Xanthate solutions are typically prepared fresh because they degrade over time; consult the SDS and technical data sheet for handling and storage guidance.
What form is potassium ethyl xanthate supplied in?
It is commonly supplied as a powder or pellet for dissolution at the plant, and also referred to as potassium O-ethyl dithiocarbonate. We provide a Certificate of Analysis per lot; it classifies under HS 2930.90 (organo-sulfur compounds, other).
What is the cost of bulk potassium ethyl xanthate?
Bulk pricing depends on grade, packaging, and volume. Submit a quote request with your target quantity and we will return current pricing plus the SDS and CoA; we do not publish fixed prices.
