Bauxite is a premium industrial mineral primarily composed of gibbsite, boehmite, or diaspore, serving as the critical foundation for the global aluminum industry. As a non-renewable resource, our high-grade bauxite is available in various natural hues—from pure white to light gray, green, or red—depending on its mineral impurities, ensuring versatility for a wide array of metallurgical and chemical applications.
Beyond its primary role in alumina production, we offer calcined bauxite processed in high-temperature rotary kilns (85°C to 1600°C). This advanced calcination process removes moisture and elevates the alumina content from a standard 57-58% to a superior 84-88%, significantly enhancing the material's efficiency for refractory materials, precision casting, and high-strength building components.

Frequently Asked Questions
Q: What is the main difference between raw bauxite and calcined bauxite?
Raw bauxite is the natural ore, while calcined bauxite is heated in a rotary kiln at temperatures up to 1600°C to remove moisture, increasing the alumina (Al2O3) content from approximately 57% to as high as 88%.
Q: In which industries is bauxite primarily used?
It is primarily used in the aluminum smelting industry, refractory material production, precision casting, the ceramics industry, and as an additive for building materials like cement and concrete.
Q: How does bauxite improve building materials?
Bauxite powder enhances the overall strength and hardness of cement and concrete, while significantly improving the material's durability and resistance to corrosion.
Q: What are the available packaging options for shipping?
We offer 1-ton jumbo bags, as well as 10kg and 25kg small bags packed within jumbo bags. We also accommodate specific custom packaging requests from our clients.
Q: Which ports are used for the delivery of bauxite?
Our primary shipping hubs are Xingang Port and Qingdao Port in China, ensuring efficient logistics for international maritime transport.
Q: Why is bauxite essential for refractory materials?
Due to its low thermal expansion, high refractoriness, and stability at high temperatures, it is an ideal raw material for linings in steel, petroleum, and chemical industrial furnaces.
