Import 90% Purity Sodium/ Potassium Amyl Xanthate — Buy in wholesale FOB from Supplier in China

This 90% purity amyl xanthate product, supplied by Sinopec Science&Tech (Tianjin) Corporation from their Tianjin Free Trade Experimental Area location, comprises two collector variants: Sodium Amyl Xanthate (PAX, CAS 7607-99-0) and Potassium Amyl Xanthate (PAK, CAS 2720-73-2). Both are thiol collectors used predominantly in froth flotation of sulfide minerals, with the amyl (pentyl) chain providing stronger hydrophobicity and lower critical micelle concentration than butyl analogues, enabling effective collection at lower dosages. The 90% purity indicates the active xanthate salt content, with typical impurities including residual alkali, xanthic acid decomposition products, and moisture from the manufacturing process involving carbon disulfide reaction with amyl alcohol and the corresponding alkali metal hydroxide.

The product is offered in flake or powder physical form, with the flake variant preferred in manual dosing operations for reduced dust generation, while powder forms suit automated gravimetric or volumetric feeding systems common in modern concentrator plants. Xanthate stability is pH-dependent: PAX and PAK solutions hydrolyse above pH 10 and decompose more rapidly in acidic conditions, with amyl xanthates showing half-lives of hours to days in aqueous solution depending on temperature and pH. The Tianjin origin is significant, as the Port of Tianjin handles substantial chemical cargo and the free trade zone status may offer bonded warehousing advantages for re-export or staged delivery to international mining operations.

Primary end-users are copper, lead, zinc, and gold mining operations employing froth flotation for sulfide ore beneficiation, where amyl xanthates serve as primary or scavenger collectors for chalcopyrite, galena, sphalerite, and pyrite-xanthate complexes. The supplier's affiliation with Sinopec, China's largest petroleum and petrochemical group, suggests access to feedstock integration and quality control infrastructure, though buyers should verify the exact corporate relationship and operational independence. Trade terms including Incoterms, packaging specifications, and lead times are not stated in the source and require direct confirmation with the Tianjin office, particularly given the hazardous material classification (xanthates are typically UN 3342, Class 4.2, spontaneous combustion risk when wet) governing international transport and storage protocols.

Sinopec Science&Tech (Tianjin) Corporation is located in the Tianjin Free Trade Experimental Area at No.199, 101-03, Tianbao Avenue, Tianjin Port Free Trade Zone, with a registered postal code of 102200. The harbour trust designation indicates a baseline verification status, though the response rate is recorded at 0.00% with no average response hours, suggesting limited recent platform-mediated engagement. The Sinopec corporate naming implies a connection to China Petroleum & Chemical Corporation, the state-owned energy and chemical giant, though the exact subsidiary, joint venture, or licensing relationship requires direct clarification, as does the extent of technical support and R&D access this affiliation provides for flotation reagent customers.

The supplier's listed specialisation in mining reagents, specifically xanthate collectors for sulfide flotation, positions them within the broader Chinese chemical export sector serving global mineral processing operations. No manufacturing certifications, production capacity figures, or specific client references appear in the available profile, and buyers should not assume ISO 9001, ISO 14001, or OHSAS 18001 certification without explicit documentation. The Tianjin Port location offers logistical advantages for sea freight, particularly to Asian and Australian mining markets, but buyers should verify whether the free trade zone status confers actual benefits such as duty deferral or bonded storage for their specific import structure.
