What are the different types of bauxite?
There are three main types of bauxite: trihydrate, monohydrate, and non-hydrated. Trihydrate bauxite is the most common form and contains the highest amount of water.

Gibbsite : Properties, Formation, Uses, Deposits
Gibbsite is a naturally occurring mineral form of aluminum hydroxide with the chemical formula Al(OH)₃. It belongs to the hydroxides and oxides mineral class and is one of the three main components of bauxite, the primary ore of aluminum. Gibbsite appears as colorless to white or gray crystals, often displaying a pearly luster and typically forms in compact, …

Bauxite
Bauxite is a result of intense leaching in a hot and humid climate with alternating wet and dry seasons and good downward drainage. The climate promotes vegetation that provides organic acids, which help to dissolve rocks in percolating water that carries more soluble components away, leaving only aluminum and also often iron as the least mobile common ions behind.

Bauxite
The methods used in mining bauxite differ somewhat in different countries and with different types of deposits. In deposits occurring in the form of extensive surface blankets or in beds and lenses interlayered with unconsolidated sediments, such as are being mined in Arkansas and in northern South America, quarrying is a common method of mining.

Aluminum
Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore. Aluminum is used in the United States in packaging, transportation, and building.

Based on the fact that bauxite clinker has minor thermal conductivity and better skid resistance and wear-resisting property, it can be used in HFST (high friction surface treatment) or the abrasion layer of asphalt mixture to replace or partly replace the existing aggregate. Bauxite clinker is classified into mainly six types according to different chemical composition contents.
