Bauxite is a premium industrial mineral ore primarily composed of gibbsite, boehmite, and diaspore. As a vital non-renewable resource, it serves as the cornerstone for the global aluminum industry, providing the essential raw material for alumina production. Our high-grade bauxite is available in various purity levels, appearing in colors ranging from pure white to light gray, green, or red depending on the natural mineral composition.
Beyond aluminum smelting, our calcined bauxite is processed in high-temperature rotary kilns (850°C to 1600°C) to remove moisture and significantly boost alumina content from approximately 57% up to 88%. This high-performance material is indispensable for the production of fused corundum, grinding agents, high-alumina slurry, and advanced refractory materials used in heavy industrial environments.

Frequently Asked Questions
Q: What is the difference between raw bauxite and calcined bauxite?
Raw bauxite is the natural ore, while calcined bauxite is heated in a rotary kiln at 850°C to 1600°C to remove moisture and increase the alumina (Al2O3) content from about 57% to as high as 88%.
Q: How is bauxite used in the refractory material industry?
Due to its low thermal expansion and high temperature volume stability, bauxite is used to create refractory bricks and linings for steel, petroleum, and chemical furnaces.
Q: Can bauxite be used to improve construction materials?
Yes, bauxite powder is frequently added to cement, mortar, and concrete to increase the overall hardness, strength, and corrosion resistance of the structure.
Q: Which ports are available for the shipment of bauxite from China?
We primarily arrange deliveries through Xingang Port and Qingdao Port to ensure efficient international shipping.
Q: What are the typical packaging options for industrial bauxite?
Standard options include 1-ton Jumbo Bags, or small bags of 10kg and 25kg placed inside a jumbo bag for easier handling.
Q: Is bauxite suitable for precision casting?
Yes, processed bauxite is used to create casting molds specifically for the machinery, instrumentation, and communication equipment industries.
