Bayer process - Wikipedia

The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide). Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can be refined to aluminium metal.

Nylon - Product Locator - BASF Corporation Plastics Portal

Ultramid polyamides from BASF are polyamide molding compounds based on PA 6, PA 66 and copolyamides such as PA 66/6. Due to their outstanding properties, these materials are indispensable in engineering for components and machine parts, such as high-quality electrical insulating materials. Ultramid polyamides are exceptional for their high mechanical strength, rigidity and thermal stability.

Mining and Refining – Process - World Aluminium

The Bayer Process is the most economic means of obtaining alumina from bauxite. Other processes for obtaining alumina from metal ores are also in use in some refineries, particularly in China and Russia, although these make up a relatively small percentage of global production.
