Sulfide Ore Flotation Applications
YuXing sodium butyl xanthate (SBX) is a flotation collector widely used in sulfide ore beneficiation. Supplied as yellow to yellow-green pellets with purity ≥90%, free alkali ≤0.2% and moisture & volatile matter ≤4.0%, SBX offers strong collecting performance and good water solubility for concentrator dosing.
SBX is effective in copper, lead-zinc and polymetallic sulfide circuits — improving mineral hydrophobicity and supporting efficient recovery when used with appropriate regulators. Compare with sodium isopropyl xanthate (SIPX) for collector selection, or browse our mining chemicals catalog. For froth stability and bubble control in the same flotation circuit, pair collectors with Methyl Isobutyl Carbinol (MIBC) flotation frother when the ore test supports it.
Why Choose YuXing SBX
1. ≥90% purity with free alkali ≤0.2% — stable active content for reliable flotation collector dosing and process control.
2. Water-soluble pellets in yellow to yellow-green form for convenient reagent preparation, packaging and industrial feeding.
3. YuXing provides TDS/MSDS/CoA documentation, flexible export packaging and technical support through our mining mineral processing services.
Frequently Asked Questions
What is sodium butyl xanthate used for?
SBX is a flotation collector for sulfide minerals in copper, lead-zinc and polymetallic ore beneficiation. It improves mineral hydrophobicity so target minerals attach to air bubbles and report to the concentrate.
What is the difference between SBX, SIPX and PAX?
SBX (butyl chain) offers balanced collecting strength for general sulfide flotation. SIPX has a shorter chain with faster kinetics; PAX has a longer chain with stronger collecting power for refractory ores. Selection depends on ore mineralogy and circuit design.
What purity does industrial sodium butyl xanthate require?
Industrial applications typically require SBX purity ≥90% with free alkali ≤0.2% and moisture & volatile matter ≤4.0%. Typical market specifications may include the following; final values are confirmed by grade, batch documents and order requirements with CoA verification.
What is the HS code for sodium butyl xanthate?
The export HS code is 29309020. YuXing provides TDS, MSDS and CoA to support customs clearance and compliance.
How is SBX dosed in a flotation plant?
SBX pellets dissolve in water for preparation and are dosed to rougher and scavenger cells per metallurgical test recommendations. Typical dosage depends on ore type, grind size and target recovery — plant trials are recommended before full-scale use.
