Import Bauxite Density: High — Buy in wholesale FOB from Supplier in China

Xinyu Inston Mineral Product Co., Ltd. offers a high-density metallurgical-grade bauxite ore with alumina content of 40-55% Al2O3, positioning it within the standard feedstock range for Bayer process alumina refineries and primary aluminum smelters. The material is classified as metallurgical grade, the principal commercial category for bauxite traded globally, distinct from refractory-grade calcined bauxite by its lower alumina, higher silica ratio, and economic optimisation for alumina extraction rather than direct refractory use. The supplier, located in Xinyu City, Jiangxi Province, sources from China's domestic bauxite belt, a region historically significant for gibbsitic bauxite deposits amenable to low-temperature Bayer digestion. The high-density characterisation suggests elevated boehmite or diaspore content, minerals that increase specific gravity and can influence digestion conditions and caustic consumption in refining.

Metallurgical bauxite at 40-55% Al2O3 typically carries 2-8% reactive silica, 15-25% total silica, and variable iron oxide content depending on deposit geology and beneficiation. The high-density designation implies a specific gravity above the 2.45 g/cm3 threshold commonly associated with low-density gibbsitic ores, with values potentially reaching 2.7-3.0 g/cm3 for diaspore-rich material. This density profile affects slurry transport rheology, settler efficiency, and mud handling volumes in refinery operations. Standard beneficiation for this grade includes washing, screening, and sometimes gravity separation to reduce silica and improve the alumina-to-silica ratio (A/S ratio) to economically viable levels, typically above 5 for modern refineries though threshold ratios vary by caustic efficiency and energy costs.

The primary market for this material comprises alumina refineries, integrated aluminum smelters, and traders supplying the global aluminum value chain. Secondary applications include cement manufacture as a corrective raw material, and limited use in refractory products where lower alumina content is acceptable. Importers should confirm the exact Al2O3 range, available A/S ratio, and moisture content for their specific refinery feed requirements, as these parameters determine caustic consumption, red mud generation rates, and overall production economics. The Jiangxi origin provides potential access to Yangtze River port logistics or overland transport to coastal export terminals, though exact shipping arrangements require direct supplier confirmation.

Xinyu Inston Mineral Product Co., Ltd. is situated at Floor 2, No. 72, North Laodong Road, Yushui District, Xinyu City, Jiangxi Province, China (postal code 338000). The company holds a harbor-tier trust designation on the platform, with a recorded response rate of 0.00 percent and zero average response hours, indicating no historical inquiry response data is available. The supplier specialises in mineral products, with this listing focused specifically on metallurgical-grade bauxite ore for industrial buyers. No verified information regarding year of establishment, registered capital, production capacity, employee count, or major clients is present in the available profile data.

The Jiangxi location is materially significant, as the province contains China's largest identified reserves of gibbsitic and diasporic bauxite. The supplier's positioning of high-density bauxite suggests targeting refineries configured for boehmite or diaspore digestion, which require higher temperature and pressure conditions than low-temperature gibbsite circuits. Buyers should independently verify the company's mining rights or trading licence status, whether material is sourced from owned concessions or third-party mines, and the consistency of supply given regulatory pressures on Chinese bauxite mining operations. The absence of response history means initial contact should establish communication reliability and technical competency before committing to volume procurement.
