Sodium Isobutyl Xanthate (SIBX) is a mining flotation collector for sulfide ores, including copper, lead, activated zinc, and gold-bearing minerals. It is offered in 85% and 90% assay as pellets or powder. It dissolves cleanly, pairs well with frothers such as MIBC, and maintains steady recovery in rougher and scavenger stages. We manufacture and supply this reagent with stable quality and tailored formulations to fit your mineralogy, circuit pH, and process targets. Complementary modifiers and depressants are available for selectivity control. Contact us to request a quote or arrange samples.

Our mining-grade product is engineered for reliable performance across variable ore feeds and operating conditions:
High assay with controlled impurities for predictable collecting power.
Controlled free alkali for compatibility with alkaline circuits and pH modifiers.
Low moisture to protect storage stability and reduce decomposition.
Flowable appearance with uniform pellets or fine powder to minimize dust and speed dissolution in make-up systems.
Clean dissolution with minimal residues to support dosing accuracy and housekeeping.
Assay ≥90% for medium-strong collecting power on sulfide ores.
Low moisture and controlled free alkali for pH compatibility and storage stability.
Uniform pellets or fine powder for rapid solution preparation; minimal residues on dissolution.
Designed for good selectivity and reduced froth entrainment in rougher and scavenger stages.
Assay ≥85% with consistent particle size and controlled moisture for predictable dosing.
Cost-effective option for circuits balancing performance and reagent spend.
Suitable for staged dosing or blends with secondary collectors (e.g., dithiophosphates, thionocarbamates) to refine selectivity and kinetics.
This collector provides dependable collection on chalcopyrite, galena, sphalerite (activated with copper), and associated gold in sulfide matrices. Use in alkaline circuits with common pH modifiers. Adjust dosage based on grind, liberation, and gangue characteristics. Pair with frothers such as MIBC or Mining Frother 2# to tune froth mobility, bubble size, and drainage. Typical starting dosages range from low to moderate g/t; confirm the optimal window via plant trials and closed-cycle evaluations. Our engineers assist with reagent screening, dosage mapping, and frother/collector pairing to manage risk during implementation.
Adjust granularity (pellets vs powder; particle size) to optimize dissolution and dosing stability.
Tune purity and free alkali for circuit pH and water chemistry, including interactions with modifiers.
Design blends with secondary collectors—e.g., Dithiophosphate 25 or Sodium Diisobutyl Dithiophosphate—for selectivity against pyrite and penalty elements, or Z‑200 (isopropyl ethyl thionocarbamate) for complex feeds.
Structured lab programs (bench tests, locked-cycle trials) followed by plant trials to validate uplift in recovery and grade. Contact us to discuss a tailored test plan.
Moisture-protected packaging options include small bags (e.g., 25 kg) and jumbo bags for bulk handling.
Palletized shipments help safeguard integrity in transit and storage.
Production scheduling and global logistics support reliable lead times and stable supply for continuous operations.
Samples available for verification prior to bulk orders; application notes provided for start-up guidance.
Compared with SIPX, this product typically offers stronger collection while retaining good selectivity; SIPX can be preferred where a gentler collector supports grade control.
Compared with SIAX, the latter may provide higher collecting power on certain difficult or fine-grained ores; this option offers balanced performance on common sulfides.
Compared with PAX, that reagent can deliver more aggressive collection and faster kinetics in specific rougher applications; this one often provides steadier selectivity.
For complex feeds, combining it with dithiophosphates or Z‑200 can sharpen selectivity against iron sulfides and manage penalty elements. We help choose the best route based on mineralogy, liberation, water chemistry, and circuit goals.
Every lot produced under DCS automation and verified by ISO9001-compliant QC protocols.
Lab checks include assay, moisture, and performance on representative ore samples.
Engineering support for reagent screening, dosage mapping, and frother/collector pairing to achieve predictable metallurgical outcomes.
Consistency from sample to mass production supports stable recovery and grade.
Grades: Available in 85% and 90% assay, pellets or powder, to match plant preferences and dissolution systems.
Storage: Keep dry, cool, and sealed; avoid moisture ingress and excessive heat to limit decomposition and maintain activity.
Trial support: We provide samples, application notes, and on-site or remote technical guidance for start-up, optimization, and scale-up. Contact us to request a quote or schedule a plant trial.
This xanthate sits in the mid-chain range, balancing hydrophobicity and selectivity for common sulfide minerals. Chain length and structure influence kinetics and selectivity (SIPX < SIBX < SIAX). Pairing with secondary collectors and the right frother enables precise control of recovery versus grade. Our portfolio spans SIBX, SIAX, and complementary collectors, enabling a unified approach from lab testwork to full-scale operations, with modifiers and depressants available to fine-tune circuit performance.
Enhance performance with frothers and modifiers from our range:
Frothers: MIBC and Mining Frother 2# to adjust froth mobility, bubble dispersion, and drainage.
Secondary collectors: Dithiophosphate 25 and Sodium Diisobutyl Dithiophosphate for selectivity control; Z‑200 for complex feeds requiring sharpened discrimination against iron sulfides.
Modifiers and depressants: Zinc Sulfate, Sodium Silicate, Sodium Sulfite, and Sodium Mercaptoacetate to condition pulp, manage gangue, and depress unwanted minerals.
