A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Transport classification per the UN Model Regulations / 49 CFR 172.101 Hazardous Materials Table. Confirm against the grade-specific SDS (Section 14) before shipping.
Potassium amyl xanthate (CAS 2720-73-2) is the potassium salt of amyl (pentyl) xanthic acid, an O-alkyl dithiocarbonate. Its established use is as a collector in the froth flotation of sulfide minerals during ore concentration. It is supplied as a flotation reagent to mineral-processing and mining operations.
Frequently Asked Questions
What is potassium amyl xanthate used for?
Potassium amyl xanthate (PAX, CAS 2720-73-2) is used as a collector in the froth flotation of sulfide minerals during ore concentration. It is supplied as a bulk flotation reagent to mineral-processing and mining operations.
What is the formula for potassium amyl xanthate?
Potassium amyl xanthate has the formula C6H11KOS2; it is the potassium salt of amyl (pentyl) xanthic acid, an O-alkyl dithiocarbonate, CAS 2720-73-2.
What does a xanthate collector do in flotation?
Xanthate collectors adsorb onto sulfide-mineral surfaces and make them hydrophobic so target minerals attach to air bubbles and report to the froth, enabling selective separation from gangue. PAX is one of the longer-chain (amyl) xanthates used for this purpose.
How does potassium amyl xanthate compare to potassium ethyl xanthate?
Both are O-alkyl dithiocarbonate flotation collectors; the difference is chain length. The amyl (C5) chain in PAX gives stronger, less selective collecting power than the shorter ethyl xanthate, which is typically more selective. Selection depends on the ore and circuit.
How is bulk potassium amyl xanthate packaged and quoted?
PAX is supplied as a flotation reagent in pellet/powder form, typically in drums, bags, or supersacks. Submit a bulk RFQ with quantity and packaging for current pricing with CoA and SDS; HS classification is 2930.90.
