SIPX Sodium Isopropyl Xanthate Flotation Collector 90% Purity for Gold Copper

SIPX (sodium isopropyl xanthate) is the most widely deployed sulfide mineral collector in the global mining industry, serving as the primary flotation reagent for gold, copper, lead, zinc, and complex polymetallic sulfide ores. Produced to a minimum active content of 90% through a controlled synthesis process, our SIPX-90 delivers consistent chain length distribution and minimal free alkali content, ensuring reliable metallurgical performance across diverse ore types and circuit configurations. The high-purity formulation reduces the probability of unwanted side reactions with gangue minerals, contributing to improved concentrate grades and reduced total reagent consumption compared to lower-purity alternatives.

The flotation mechanism of SIPX relies on the chemisorption of the xanthate ion (C³H&sup7;OCS²&supmin;) onto sulfide mineral surfaces, where the polar dithiocarbonate head group forms strong bonds with metal cation sites on galena, chalcopyrite, sphalerite (after copper activation), pyrite, and gold-bearing sulfides. The non-polar isopropyl hydrocarbon chain extends outward from the mineral surface, rendering it hydrophobic and enabling stable bubble attachment in the flotation pulp. SIPX exhibits moderately strong collecting power with good selectivity against iron sulfides at controlled pH (8.5-11.0), making it the reagent of choice for rougher and scavenger flotation stages across a broad range of sulfide ore types. The pellet form offers superior handling characteristics compared to powder, with reduced dust generation during reagent preparation and dosing.

• Guaranteed 90% Minimum Active Content: Each production batch is verified by UV-Vis spectrophotometric assay to contain 90% or higher sodium isopropyl xanthate. High active content ensures predictable collector strength and minimizes the mass of inert carrier material introduced to the flotation circuit, reducing the risk of unintended pulp chemistry effects.
• Consistent Chain Length Purity: The controlled synthesis process minimizes contamination by homologous xanthates of different chain lengths (ethyl, butyl, amyl), which would introduce variable flotation kinetics and selectivity characteristics. Chain length purity exceeding 95% C3 (isopropyl) is standard for all production.
• Low Free Alkali Formulation: Free alkali content is maintained below 0.2%, significantly lower than the industry standard of 0.5%. Low free alkali reduces the risk of uncontrolled pH elevation in the flotation circuit and minimizes collector decomposition during storage, extending effective shelf life.
• Pellet Form for Safe Handling: SIPX-90 pellets (nominal 3-5mm) provide superior handling characteristics with significantly reduced dust generation during bag opening, hopper charging, and mixing tank addition compared to powder forms. The pellet form dissolves rapidly in water with mild agitation, achieving full dissolution within 5-10 minutes at 10% concentration for standard reagent make-up.
• Versatile Across Sulfide Ore Types: SIPX delivers effective flotation performance for gold-bearing pyrite and arsenopyrite ores, porphyry copper and copper-gold ores, galena-sphalerite lead-zinc ores, and complex polymetallic sulfide deposits. The broad applicability makes SIPX the logical first-choice collector for operations processing variable ore blends.
• Cost-Effective Bulk Supply: With a production capacity of 800 tons per month and strategically located warehousing, we offer competitive delivered pricing for bulk orders to mining operations throughout Latin America, with reliable lead times of 10-20 days for standard orders.

SIPX-90 is the primary collector for a broad spectrum of sulfide mineral flotation applications. In gold processing, SIPX is the standard collector for gold-bearing pyrite and arsenopyrite ores, typically dosed at 50-150 g/t in rougher flotation circuits operating at pH 8.5-10.5 with copper sulfate as an activator when processing low-pyrite ores. For copper and copper-gold porphyry operations throughout the Andean region, SIPX serves as the main sulfide collector at dosages of 30-80 g/t, often in combination with dithiophosphate co-collectors for enhanced precious metal recovery. In lead-zinc sequential flotation circuits, SIPX is the preferred galena collector in the lead flotation stage at pH 8.5-10.0, typically at 50-100 g/t dosage with sodium cyanide or zinc sulfate as sphalerite depressants. Following lead flotation, copper sulfate-activated sphalerite is recovered with SIPX at 60-120 g/t in the zinc circuit. Additional applications include nickel sulfide flotation, cobalt recovery from pyrite concentrates, and bulk sulfide flotation ahead of selective separation. The pellet form is compatible with all standard reagent preparation systems including agitated mix tanks, ring main distribution networks, and peristaltic or diaphragm metering pump dosing configurations.

Each production batch of SIPX-90 undergoes complete quality control analysis in our ISO 9001 certified laboratory prior to release for shipment. Analysis includes active content determination via UV-Vis spectrophotometry, free alkali titration, moisture content determination, appearance verification, and dissolution rate testing. Certificates of analysis with full traceability to production batch number and manufacturing date are provided with every shipment. Standard packaging options include 25kg polyethylene-lined woven polypropylene bags palletized on 1-ton shrink-wrapped pallets (40 bags per pallet), 120kg or 200kg sealed steel drums with removable lids, and 850kg flexible intermediate bulk containers (FIBC/supersacks) with bottom discharge spouts for high-throughput operations. All packaging incorporates moisture-barrier protection to maintain product integrity during ocean transport. Storage recommendations include a dry, well-ventilated warehouse area below 35°C and away from direct sunlight, acids, and oxidizing agents. Shelf life of 6 months in original sealed packaging is guaranteed. Our applications support team is available for reagent circuit audits, dosage optimization recommendations, and metallurgical troubleshooting at client operations.
