- Availability: Available

**PAX (potassium amyl xanthate).** A very strong collector for all sulphide ores, including copper-nickel sulphide ore, zinc ore, and gold bound in pyrite. PAX is not very selective and tends to float iron sulphides as well, unless it is used with depressants.

**SIBX (sodium isobutyl xanthate).** A strong collector for non-ferrous metal sulphide ores, mainly copper, lead and zinc. SIBX works especially well on copper ores and on pyrite.

Other types in our range: sodium ethyl xanthate, sodium isopropyl xanthate and potassium isobutyl xanthate. All are pellets with a purity of at least 90%.

Xanthate packs carry hazard labels and are shipped under dangerous goods regulations. Follow the safety data sheet (SDS) when handling it. Contact us for the specification of each type and a quotation.
