Sulfide Ore Flotation Applications
YuXing potassium amyl xanthate (PAX) is a strong xanthate flotation collector used in sulfide ore beneficiation. Supplied as yellow water-soluble pellets with purity ≥90%, free alkali ≤0.2% and moisture & volatile matter ≤4.0%, PAX provides stronger collecting power than shorter-chain xanthates for demanding flotation circuits.
PAX is commonly evaluated for copper, sulfide-associated gold and complex sulfide ores where stronger mineral collection is required. For collector selection, compare PAX with Sodium Butyl Xanthate (SBX), Sodium Isopropyl Xanthate (SIPX) and the full mining chemicals catalog.
How PAX Works in Sulfide Ore Flotation
PAX has a longer amyl chain than SIPX and SBX, giving it stronger collecting power in sulfide ore flotation. It adsorbs on target mineral surfaces, increases hydrophobicity and helps valuable sulfide minerals attach to air bubbles and report to the concentrate.
Because PAX is a strong collector, dosage and selectivity must be controlled through ore testing. Practical performance depends on ore mineralogy, grind size, pH, pulp chemistry, flotation stage and the selected frother or regulator system. For bubble control and froth stability, PAX may be evaluated with Methyl Isobutyl Carbinol (MIBC) flotation frother when plant testing supports the combination.
PAX vs SBX vs SIPX Collector Selection
| Collector | Collecting Strength | Typical Use |
|---|---|---|
| SIPX | Moderate, faster kinetics | General sulfide flotation where faster circuit response is required. |
| SBX | Balanced | Copper, lead-zinc and polymetallic ores where recovery and selectivity need balance. |
| PAX | Strong | Gold-bearing sulfide, copper and complex sulfide ores where stronger collection is required. |
For selective copper circuits, buyers may also compare xanthates with Aerofloat 25 Equivalent or Ammonium Dibutyl Dithiophosphate depending on ore association, penalty elements and recovery targets.

How to Select a Potassium Amyl Xanthate Supplier
- Confirm PAX purity ≥90%, free alkali, moisture and appearance against your plant specification.
- Request TDS, MSDS and batch CoA before confirming bulk purchase.
- Share ore type, flotation stage, current reagent scheme and recovery target for collector selection support.
- Confirm packaging, destination port, lead time, document requirements and quotation validity before shipment.
- Evaluate whether your circuit needs PAX, SBX, SIPX, dithiophosphate collectors or MIBC frother support.
Why Choose YuXing PAX
- ≥90% purity with free alkali ≤0.2% for reliable flotation collector dosing in demanding concentrator circuits.
- Water-soluble yellow pellets for convenient reagent preparation, export packaging and industrial feeding.
- Strong collecting power for gold-bearing sulfide, copper and complex sulfide ore flotation applications.
- TDS, MSDS, CoA, export packaging support and technical communication through our mining mineral processing services.
PAX HS Code, Collector Strength and Alternatives
Potassium amyl xanthate is a strong xanthate collector, but customs classification and purchasing specifications require more than the abbreviation PAX. Confirm chemical name, active content, physical form and destination-country HS classification with the importer before shipment; an HS code used in one market may not automatically apply in another.
For circuit trials, compare PAX with sodium amyl xanthate where the counter-ion or product form matters. Where selectivity must be balanced against collector strength, review dithiophosphate collectors and test the complete collector-frother-modifier scheme on the actual ore.
Frequently Asked Questions
What is potassium amyl xanthate used for?
PAX is a strong flotation collector for sulfide minerals in copper, sulfide-associated gold and complex sulfide ore beneficiation. Its longer amyl chain provides stronger collecting power than SBX or SIPX for difficult ores.
Is PAX stronger than SBX and SIPX?
Yes. PAX generally has stronger collecting power than SBX and SIPX because of its longer amyl chain. That strength can improve recovery in difficult ores, but dosage and selectivity should be confirmed by flotation testing.
Is PAX suitable for gold-bearing sulfide ores?
PAX is commonly evaluated for sulfide-associated gold ores and complex sulfide circuits where stronger collection is required. Final reagent selection should follow ore mineralogy and metallurgical test results.
What is the difference between PAX, SBX and SIPX?
PAX offers the strongest collecting power. SBX is balanced for general use, while SIPX has faster kinetics. Selection depends on ore mineralogy, selectivity requirements and circuit design.
What purity does industrial potassium amyl xanthate require?
Industrial applications typically require PAX purity ≥90% with free alkali ≤0.2% and moisture & volatile matter ≤4.0%. YuXing can provide CoA verification for supplied batches.
Can YuXing provide TDS, MSDS and CoA?
Yes. YuXing can provide TDS, MSDS and batch CoA to support technical review, procurement approval and customs clearance.
How should potassium amyl xanthate be stored?
Store PAX in sealed packaging in a cool, dry and well-ventilated area. Keep away from moisture, heat and incompatible materials, and follow the supplied MSDS.
What is the HS code for potassium amyl xanthate?
The export HS code is 29309020. Confirm final import declaration requirements with your local customs broker before shipment.
How is PAX dosed in a flotation plant?
PAX pellets dissolve in water and are dosed according to metallurgical test recommendations. Because PAX is a strong collector, dosage is typically lower than shorter-chain xanthates and should be validated through plant trials.
