Bauxite, also known as bauxite ore or alumina ore, is a type of ore that contains aluminum hydroxide minerals.
Chemical compositionAluminum oxide 40%-70%, silicon dioxide, iron oxide, titanium oxide, etc.
Mineral compositionGibbsite, boehmite, diaspore, etc.
Varied colors, commonly including white, grayish-white, light yellow, brown, etc.
Mohs hardness: Density: approximately 2.4-2.5 g/cm.
Classification by mineral composition
| Basic types | Subtypes |
| Monohydrate high-alumina bauxite | Monohydrate high-alumina bauxite |
| Gibbsite-Illite type (D-P type) | |
| Boehmite-Kaolinite type (B-K type) | |
| Gibbsite-Illite type (D-I type) | |
| Gibbsite-Illite type (D-I type) | |
| Trihydrate bauxite (G type) | Trihydrate high-alumina bauxite |
| Content | Raw bauxite | Bauxite clinker |
| Definition | Bauxite ore extracted from the mine that has not been calcined at high temperatures. | The product of bauxite raw material after high-temperature calcination. |
| Hardness | Relatively soft and quite loose | Higher hardness and dense structure |
| Appearance | Varied colors, including grayish-white, dark gray, brown, etc., with a relatively rough surface. | The colors are relatively uniform, mostly white or light gray, and the surface is relatively smooth after calcination. |
| Differences in usage | 1.In the alumina industry, it is an important raw material for the extraction of alumina. 2.It can also be used to make some basic refractory materials, but due to its lower performance compared to clinker, it is generally used in applications with lower refractory requirements. |
1.It is a key raw material for making high-grade refractory materials, such as linings for steelmaking ladles and blast furnaces. 2.It is also used in the abrasive industry, where its high hardness allows it to be used as a grinding material. |
