These collectors are core reagents for selective flotation of sulfide ores. They support recovery of copper, lead, zinc, gold, silver, nickel, and cobalt.
We manufacture in Laiyang Chemical Industry Park, Shandong, and integrate production, R&D, trade, and technical services. DCS automation and ISO9001 controls help keep batch quality stable. Flexible minimum order quantities and a digital showroom support trials and factory tours. Contact us to discuss your collectors program or request a quote for SIBX and SIAX.
Xanthate is an organosulfur collector that adsorbs on sulfide mineral surfaces and makes them hydrophobic. This promotes bubble attachment, fast kinetics, and improved mineral recovery. Chain length and substituents influence strength and selectivity, enabling performance tuning by ore type and circuit conditions. In many plants, these reagents are staged or blended with complementary collectors and balanced with frothers and modifiers to optimize recovery and grade.
We supply two primary collectors for common sulfide circuits: Sodium Isobutyl Xanthate (SIBX) and Sodium Isoamyl Xanthate (SIAX). Both are engineered for clean dissolution, predictable dosage response, and stable performance across typical plant pH ranges. Selection is guided by mineralogy, water chemistry, and concentrate quality targets.
SIBX delivers robust collecting power with useful selectivity in copper, lead, and gold sulfide circuits. When pH and depressants are controlled, it supports strong recovery without excessive pyrite activation, helping produce cleaner concentrates. It dissolves readily for make‑up solutions and fits staged addition strategies to balance kinetics and grade. Quality is verified under ISO9001 protocols, and packaging is designed for safe handling. Ask us for SIBX dosage guidance matched to your circuit conditions.
SIAX provides higher collecting strength for refractory sulfides and mixed copper–nickel–cobalt ores. It can lift recovery in challenging circuits. Pairing with thionocarbamates or dithiophosphates helps maintain selectivity. Manufactured with full‑process DCS control, SIAX offers uniform active content and predictable plant response with low variability across campaigns. In copper–nickel circuits, targeted blending strategies often balance recovery and grade.
To sharpen selectivity and improve concentrate quality, we supply synergistic reagents that complement the main collector action:
Sodium Diethyl Dithiocarbamate (DETC) to enhance precious metal selectivity in gold and silver flotation.
Isopropyl Ethyl Thionocarbamate (Z‑200) for improved selectivity over gangue.
Sodium Diisobutyl Dithiophosphate and Dithiophosphate 25 for balanced kinetics and tighter grade control.
These collectors are commonly blended with SIBX or SIAX to fine‑tune performance by ore type.
Stable froth and circuit control rely on the right supporting reagents:
MIBC and Mining Frother 2# for clean, stable froth with controlled bubble size; selection depends on gas rate and cell design.
Zinc Sulfate as a depressant to manage sphalerite in polymetallic ores.
Sodium Sulfite to modify surface chemistry and support selective recovery.
Sodium Silicate as a dispersant to reduce slime coating and improve selectivity in fines‑rich feeds.
These auxiliaries help balance recovery and grade under varying water chemistries.
These compounds can decompose under heat or moisture, producing odors and flammable gases. Follow site controls for transport, storage, and disposal.
Store in cool, dry, well‑ventilated areas.
Keep away from acids and incompatible materials.
Use appropriate PPE during handling.
Our production and packaging systems prioritize stability to support compliant storage and reduce handling risks in transit and onsite.
Every ore body responds differently to collectors. Our mineral processing research institute runs bench and pilot test work to tailor dosage, blends, and addition points. The “one mine, one product” and “one enterprise, one reagent” approach aligns reagent chemistry with mineralogy, water chemistry, and plant configuration. This delivers repeatable performance and plant‑specific programs from sample to mass production. Contact us to design a customized blend by ore type.
Located in Laiyang Chemical Industry Park, our facility operates with full‑process DCS automation for safety and consistency. ISO9001 quality systems and comprehensive testing help ensure stable active content and clean dissolution for SIBX and SIAX. We offer flexible MOQ and responsive logistics. Factory tours and our digital showroom are available for transparent capability review.
SIBX offers balanced collecting strength for copper and lead. Depressants such as Zinc Sulfate help manage zinc where needed. Blending SIBX with dithiophosphate refines selectivity and concentrate grade in polymetallic circuits.
For auriferous sulfides, SIBX combined with selective dithiocarbamates can enhance gold and silver recovery while limiting gangue entrainment. Frother choice—MIBC or Mining Frother 2#—tunes froth stability for cleaner concentrates.
SIAX delivers strong collection in nickel–cobalt circuits and is often staged with Z‑200 to improve selectivity. Sodium Silicate helps disperse slimes, and controlled pH moderates unwanted activation for higher recovery with manageable concentrate quality.
SIBX is formulated for stable active content, rapid dissolution into make‑up solutions, and low residual insolubles. Packaging and routine quality checks support safe handling and consistent dosing response. Request a specification overview or guidance on SIBX solution make‑up behavior.
SIAX features uniform granule characteristics for predictable wetting and solution preparation. It delivers high collecting strength with controlled selectivity when paired with circuit modifiers, supporting reliable performance in refractory sulfide circuits.
We supply secure packaging options designed for safe transport and storage, with documentation aligned to applicable regulations. Our logistics team coordinates timely delivery, and technical support helps ensure smooth start‑up and stable performance in your flotation circuit. Contact us to discuss packaging options and delivery schedules.
Our engineers provide reagent screening, dosage curves, frother pairing, and pH control guidance. Test protocols are translated into plant adjustments for sustained recovery and grade. Ask about optimization services and collector blending programs for plant circuits.
This category centers on SIBX and SIAX as core solutions for sulfide flotation. Programs can be tailored for copper, lead, zinc, gold, silver, nickel, and cobalt flowsheets. Capability is supported by ISO9001, DCS automation, logistics, and our mineral processing research institute. Contact us to start a pilot program or request a quote for a complete collector package.
