Abrasives and Polishes

Technical minerals commonly used in the abrasives and polishing industry are:

1. Silicon carbide: It is one of the most common abrasives used in the manufacture of sandpaper, abrasive discs and sharpening stones. It is also used in the manufacture of refractory and ceramic materials.

2. Aluminum oxide: is another common abrasive used in the manufacture of cutting wheels and discs, as well as in the preparation of metal surfaces before painting.

3. Diamond: it is one of the hardest and most resistant materials known and is used in the manufacture of cutting and polishing tools, such as drill bits and diamond discs.

4. Cubic Boron Nitride: It is a material similar to diamond in terms of hardness and strength, and is used in the manufacture of high-quality cutting and polishing tools.

5. Cerium oxide: used in the polishing industry to give high quality finishes to glass, precious stones and optical components.

6. Silica: used in the manufacture of sandpaper and abrasive discs, as well as in the preparation of surfaces before painting.
7. Pumice: is a porous volcanic mineral used in the manufacture of soft abrasive products to clean and polish delicate surfaces.
8. Expanded glass: used as an abrasive in the manufacture of cleaning and polishing products, as well as in construction as a lightweight aggregate for the production of concrete and mortar.

These are just a few examples of technical minerals used in the abrasives and polishing industry. There are many other minerals used in this industry, and the choice of mineral depends on the type of application and the desired end result.
