About this product

Product information from the supplier.

Bauxite is a high-grade industrial mineral complex primarily composed of gibbsite, boehmite, and diaspore. As a critical non-renewable resource, it serves as the primary feedstock for the global aluminum industry. While pure bauxite is white, our premium ores exhibit characteristic light gray, green, or red hues depending on the natural impurity profile, ensuring versatility across multiple metallurgical and chemical applications.

Our processed calcined bauxite is produced through high-temperature calcination (850°C to 1600°C) in advanced rotary kilns. This critical thermal process removes moisture and volatile components, significantly boosting the alumina (Al2O3) content from a raw state of 57-58% to a professional industrial grade of 84-88%, making it an indispensable material for high-performance refractories and precision smelting.

Frequently Asked Questions

Q: What is the difference between raw bauxite and calcined bauxite?

Raw bauxite is the natural ore. Calcined bauxite is processed at temperatures between 850°C and 1600°C to remove moisture and impurities, increasing Al2O3 content from ~58% to 84-88%.

Q: Which ports are used for the shipment of Bauxite from China?

Our products are primarily delivered via Xingang Port and Qingdao Port, ensuring efficient international maritime logistics.

Q: How does bauxite improve building materials like concrete?

Bauxite powder enhances the overall strength and hardness of cement and concrete while significantly increasing durability and corrosion resistance.

Q: Is bauxite suitable for precision casting in the machinery industry?

Yes, processed bauxite can be converted into various casting molds, which are widely used in communication, instrumentation, and machinery equipment industries.

Q: What are the typical packaging options for bulk orders?

We offer 1-ton jumbo bags, as well as 10kg or 25kg small bags packed within jumbo bags, or customized packaging based on client requests.

Q: Why is bauxite used in refractory materials for the steel industry?

Due to its low thermal expansion, high refractoriness, and high-temperature volume stability, it is an ideal raw material for linings in steel and non-ferrous metallurgy.
