Sodium Isopropyl Xanthate (SIPX) at 90 percent purity is a powerful and selective collector specifically formulated for the flotation of non-ferrous metal sulfide ores, with particular effectiveness in silver and gold-bearing sulfide systems. With an annual production capacity of 50,000 tons from our fully automated chemical facility in Shandong, China, we are one of the largest and most reliable suppliers of xanthate flotation reagents serving the global mining industry. SIPX demonstrates exceptional collecting power for copper sulfides including chalcopyrite and chalcocite, gold-bearing pyrite and arsenopyrite, and silver minerals such as argentite and pyrargyrite. Its moderate selectivity profile makes it an ideal primary collector for polymetallic flotation circuits processing Ag-Au-Cu ores commonly found in Mexican and Peruvian mining operations.

• Superior Silver and Gold Recovery: SIPX exhibits strong collecting properties for native gold, electrum, and silver sulfide minerals. In auriferous iron ore and copper-gold flotation circuits, SIPX consistently achieves precious metal recovery rates 3 to 8 percentage points higher than equivalent amyl or ethyl xanthate formulations, delivering measurable improvements in project economics for precious metals producers.
• Reliable 90 Percent Active Purity: Our fully automated production line with continuous process monitoring ensures every batch meets the minimum 90 percent active ingredient specification. Free alkali content is maintained below 0.2 percent, minimizing unwanted pH elevation in the flotation circuit that can compromise selectivity and increase lime consumption.
• Massive Production Capacity: With 50,000 tons annual xanthate production capacity, we can fulfill bulk orders for large-scale mining operations with consistent, uninterrupted supply. Our strategic factory location adjacent to Qingdao Port enables efficient container loading and competitive ocean freight to Pacific and Atlantic destinations including Mexican ports such as Manzanillo and Veracruz.
• Versatile Circuit Application: SIPX performs effectively in rougher, scavenger, and cleaner flotation stages across a pH range of 8 to 11. It is compatible with common frothers including MIBC, pine oil, and terpineol, and can be blended with dithiophosphate collectors to fine-tune the recovery-selectivity balance for complex ore types.
• Multiple Packaging Configurations: Available in UN-approved 110kg or 160kg steel drums with polyethylene liner, 850kg wooden box jumbo bags, and 25-50kg woven bags to match customer handling equipment and consumption rates. Standard 20-foot container loads accommodate 14.74 metric tons in drum packaging or 17 metric tons in wooden boxes.
• Sample Support and Technical Service: We provide complimentary 1-kilogram samples for laboratory flotation testwork. Our metallurgical team offers technical guidance on dosage optimization, reagent combination strategies, and circuit troubleshooting based on over 30 years of mining industry experience operating our own mines.

SIPX is the collector of choice for silver and gold sulfide ore flotation across major Latin American mining jurisdictions. In Mexican operations processing silver-lead-zinc ores from districts such as Fresnillo and Zacatecas, SIPX serves as the primary collector in bulk sulfide flotation, recovering silver-bearing galena, sphalerite, and pyrite into a bulk concentrate for subsequent selective separation. It is also extensively used in copper-gold porphyry flotation circuits where it acts as a robust primary collector for chalcopyrite-bornite assemblages while providing supplementary gold recovery from associated pyrite. For copper-lead oxide ores that are refractory to conventional sulfide flotation, SIPX combined with sulfidization pretreatment delivers satisfactory recovery results. The reagent is also suitable for nickel sulfide flotation and antimony mineral recovery in appropriate circuit conditions.

SIPX is packaged in UN-approved containers suitable for international dangerous goods transport by sea, air, rail, and truck. Our factory operates under an ISO9001:2000 certified quality management system with fully automated production control ensuring batch-to-batch consistency. Each production lot is tested for active content, free alkali, moisture, and solubility before release. Certificates of Analysis are provided with every shipment. The product should be stored in a dry, well-ventilated area away from heat, moisture, and direct sunlight. Under proper storage conditions, shelf life extends to 12 months. Technical data sheets, material safety data sheets in English and Spanish, and metallurgical application guidance are available upon request.
