Bauxite Ore is added by GregTech. It can be found in most types of forest biomes: Forest, Plains, Rainforest, Autumn Woods, Birch Forest, Forested Hills, Forested Island, Green Hills, Meadow, Redwood Forest, Woodlands, and so forth. In the Twilight Forest, Bauxite can also be found in Dense Twilight Forest, Dark Forest, and Enchanted Forest.
Unlike most ores, Bauxite Ore cannot be smelted directly into ingots. Instead, it must be processed in a Macerator or Industrial Grinder to be ground into dust. Currently, Bauxite Ore's sole purpose is to be ground into dust using either of these methods and then placed in an Industrial Centrifuge or an Industrial Electrolyzer to create Aluminium Dust, Titanium Dust, Hydrogen Cells, and Compressed Air Cells.
