A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Transport classification per the UN Model Regulations / 49 CFR 172.101 Hazardous Materials Table. Confirm against the grade-specific SDS (Section 14) before shipping.
Sodium isobutyl xanthate (CAS 25306-75-6, SIBX), an organosulfur dithiocarbonate salt. Used as a collector reagent in the froth flotation of sulfide minerals for recovery of base and precious metals.
Frequently Asked Questions
What is sodium isobutyl xanthate (SIBX) used for?
SIBX (CAS 25306-75-6) is a collector reagent used in the froth flotation of sulfide minerals to recover base and precious metals, including copper, lead, zinc, and gold ores. It is an organosulfur dithiocarbonate salt supplied to mineral-processing operations.
What is the chemical formula and structure of SIBX?
SIBX has the formula C5H9NaOS2 — the sodium salt of isobutyl xanthic (dithiocarbonate) acid. It belongs to the xanthate family of flotation collectors and is supplied as a solid (pellets, granules, or powder). See the SDS for handling and storage requirements.
What is xanthate used for in mineral processing?
Xanthates are anionic collector reagents that adsorb onto sulfide-mineral surfaces, making them hydrophobic so they attach to air bubbles and report to the froth concentrate. Different alkyl chains (ethyl, isobutyl, amyl) give different selectivity and strength; isobutyl offers a balance of selectivity and recovery.
What is the HS code for sodium isobutyl xanthate?
It is classified under HS 2930.90 (organo-sulfur compounds, other). Confirm the final tariff classification and any import documentation with your customs broker for your destination.
What is the cost of bulk SIBX and how is it packaged?
SIBX is supplied as a solid in bags, drums, or bulk for flotation circuits; pricing is volume-dependent. We do not quote a fixed list price — request a bulk quote with your required quantity and form to receive current pricing along with a Certificate of Analysis and SDS.
