Bauxite is a premium industrial mineral ore, primarily composed of gibbsite, boehmite, and diaspore. As a vital non-renewable resource, it serves as the fundamental bedrock for the global aluminum industry. Our high-purity bauxite is available in various natural hues—ranging from pure white to light gray, green, or red—depending on the specific mineral impurities, ensuring versatility for a wide array of metallurgical and chemical applications.
To enhance industrial efficiency, we provide calcined bauxite, processed in high-temperature rotary kilns (850°C to 1600°C). This thermal treatment removes moisture and volatile components, significantly boosting the alumina (Al2O3) content from a baseline of 57-58% to an optimized range of 84-88%. This specialized processing makes our bauxite an ideal choice for high-performance refractories, precision casting, and advanced building materials.

Frequently Asked Questions
Q: What is the difference between raw bauxite and calcined bauxite?
Raw bauxite is the natural mineral ore. Calcined bauxite is produced by heating raw bauxite to temperatures between 850°C and 1600°C, which removes moisture and increases the Al2O3 content from approx. 57% to 88%.
Q: Which ports are used for shipping your bauxite products?
Our products are primarily shipped through Xingang Port and Qingdao Port, China, ensuring efficient international delivery.
Q: Can bauxite be used in the construction industry?
Yes, bauxite powder is used as an additive in cement, mortar, and concrete to improve material strength, hardness, and overall corrosion resistance.
Q: What are the primary industrial applications of bauxite?
Bauxite is mainly used in aluminum smelting, the production of refractory materials for steel/petroleum industries, precision casting, and the manufacture of fused corundum.
Q: What packaging options are available for bulk orders?
We offer 1-ton Jumbo Bags, as well as 10Kg or 25Kg small bags packed within jumbo bags, or any other packaging as per customer request.
Q: How does bauxite contribute to refractory materials?
Due to its low thermal expansion and high refractoriness, bauxite provides excellent high-temperature volume stability, which is critical for linings in non-ferrous metallurgy and chemical plants.
