Bauxite (bauxite ore) waxaa loola jeedaa erey wadareed oo macdan ah oo laga isticmaali karo warshadaha, inta badan ka kooban gibbsite, boehmite, ama qurba-joog. Waa kheyraad aan dib loo cusboonaysiin karin. Bauxite saafi ah waa midab cad wuxuuna u muuqan karaa cawl khafiif ah, cagaar khafiif ah, ama casaan khafiif ah oo ay ugu wacan tahay wasakhyo kala duwan. Bauxite waxay leedahay codsiyo warshadeed oo ballaaran. Dhinaca kale, waa alaabta ugu muhiimsan ee soo saarista aluminium, taas oo iyaduna soo saarta aluminium. Dhanka kale, waxaa si weyn loogu isticmaalaa sida alaabta ceeriin ee warshadaha sida alaabta refractory, corundum isku qasan, alaabta shiidi, alaabta dhoobada, alaabta kiimikada, iyo alumina sare leh slurry.
Calcined bauxite contains hydrated alumina and aluminum hydroxide, obtained by calcining high-quality bauxite at high temperatures (85°C to 1600°C) in a rotary kiln. It is one of the main raw materials for producing aluminum. Compared with the original bauxite, after removing moisture through calcination, the alumina content of the calcined bauxite can be increased from about 57% to 58% of the original bauxite to 84% to 88%.

- Warshadaha aluminium: bauxite waxay leedahay aluminium sare oo aluminium ah waana shay ceeriin ah oo muhiim u ah warshadaha dhalada aluminium;
2. Ku shubista saxda ah: bauxite waxaa laga samayn karaa noocyo kala duwan oo ah caaryada tuurista ka dib habaynta, inta badan loo isticmaalo isgaarsiinta, qalabka, mishiinada iyo warshadaha qalabka;
3. Qalabka dib-u-celinta: bauxite waxay leedahay sifooyin wanaagsan sida balaadhinta kulaylka hooseeya, dib-u-soo-celinta sare, iyo xasilloonida heerkulka sare, taas oo ka dhigaysa alaabta ceeriin ee caadiga ah ee alaabta dib-u-celinta. Qalabka refractory ee ka samaysan ayaa si weyn loogu isticmaalaa birta, birta aan birta ahayn, batroolka, kiimikooyinka iyo goobaha kale ee warshadaha.
4. Qalabka dhismaha: budada bauxite waxay hagaajin kartaa xoogga iyo adkaanta alaabta sida sibidhka, hoobiye, iyo shubka, iyadoo sidoo kale kor u qaadaysa adkaysigooda iyo caabbinta daxalka.
