Import Bauxite — Buy in wholesale FOB from Supplier in China

Xinyu Inston Mineral Product Co., Ltd. offers refractory grade calcined bauxite originating from Jiangxi Province, China, with a guaranteed minimum alumina content of 85% Al2O3 and maximum iron oxide of 1.6% Fe2O3. The material presents as grey in colour and carries a minimum bulk density of 3.3 g/cm3, indicating substantial thermal mass and resistance to slag penetration in high-temperature environments. This specification sits in the upper tier of refractory bauxite grades, suitable for demanding applications where standard metallurgical bauxite would fail.

The raw material undergoes calcination, a high-temperature firing process that drives off combined water and converts gibbsite or boehmite phases into corundum and mullite, thereby increasing hardness and refractoriness. Typical impurities controlled in this grade include titanium dioxide (4% max), combined calcium and magnesium oxides (0.4% max), and combined potassium and sodium oxides (0.4% max), the latter being particularly critical as alkali fluxes dramatically lower the refractoriness and promote glassy phase formation. Particle size distribution, though not stated, is typically specified by buyers as 0-1mm, 1-3mm, 3-5mm, or 5-8mm fractions for monolithic refractory blending.

Primary buyers include steel mill refractory departments, ladle furnace operators, cement kiln maintenance crews, and castable refractory manufacturers who formulate low-cement and ultra-low-cement products. The 85% Al2O3 grade bridges the gap between standard Chinese bauxite (80-83%) and premium Guyanese or Chinese rotary kiln bauxite (86-88%), offering a cost-effective solution for medium-duty linings. Trade terms, packaging options, and confirmed MOQ should be discussed directly with Xinyu Inston Mineral Product Co., Ltd., as these details are not specified in the listing materials.

Xinyu Inston Mineral Product Co., Ltd. is located at Floor 2, No.72, North Laodong Road, Yushui District, Xinyu City, Jiangxi Province, China, postal code 338000. Jiangxi is a historically significant province for Chinese refractory minerals, with substantial bauxite reserves and established calcination infrastructure. The company holds a Harbor trust tier on the platform, though its response rate is recorded at 0.00% with zero average response hours, indicating minimal or no engagement with inbound enquiries through this channel. Buyers should not rely on rapid quotation turnaround and should plan direct contact through alternative means.

The listing provides specific chemical composition parameters and physical properties, suggesting technical familiarity with refractory grade material, though no manufacturing capacity, annual output, or facility details are disclosed. No certifications such as ISO 9001, environmental compliance, or refractory industry accreditations are mentioned. The company does not state its years in operation, employee count, or client references. Buyers should verify export licence status, calcination capability (shaft kiln versus rotary kiln), and quality control documentation independently before committing to trial orders.
