Description

Bauxite CAS NO 1318-16-7 is the primary natural ore of aluminum, consisting primarily of aluminum hydroxide minerals such as gibbsite, boehmite, and diaspore, along with various impurities. Its primary commercial value lies in its role as the essential raw material for the production of alumina (aluminum oxide), which is subsequently processed into aluminum metal. This critical industrial mineral is indispensable for the global aluminum industry, as well as for the production of abrasives, refractories, and proppants.

Application

• Primary Aluminum Production: The predominant use, serving as the feedstock for alumina refineries via the Bayer process.
• Refractory Manufacturing: Calcined bauxite is used to produce high-alumina refractory bricks and castables for furnaces, kilns, and incinerators due to its high melting point and stability.
• Abrasive Products: Used in the manufacture of fused aluminum oxide (brown fused alumina) for grinding wheels, sandpaper, and blasting media.
• Proppants for Oil & Gas: Sintered bauxite is processed into high-strength ceramic proppants used in hydraulic fracturing (fracking) to keep fissures open.
• Cement Production: Used as a source of alumina in the manufacture of special cements, such as calcium aluminate cement.
• Chemical Applications: As a source material for aluminum chemicals, including aluminum sulfate (alum) used in water treatment.
• Adsorbent & Catalyst Carrier: Activated forms can be used in adsorption processes and as a substrate for catalysts.

Quality Control

Our bauxite is sourced and processed to meet stringent industry specifications for key parameters such as available alumina (Al2O3) content, silica (SiO2) modulus, and iron oxide (Fe2O3) levels. Quality is verified through rigorous in-process and final batch testing. Certificates of Analysis (COA) detailing chemical composition and physical properties are available for every shipment to ensure consistency and performance for your specific application.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperature (15-25°C). Keep away from incompatible materials such as strong acids. As a mineral product, it is generally stable but should be protected from excessive moisture to prevent caking.
