Bauxite (bauxite ore) e bolela lentsoe le kopaneng la liminerale tse ka sebelisoang indastering, haholo-holo tse entsoeng ka gibbsite, boehmite, kapa diaspore. Ke mohloli o sa tsosolositsoeng. Bauxite e hloekileng e na le 'mala o mosoeu' me e ka bonahala e le bohlooho bo bobebe, botala bo khanyang, kapa bofubelu bo khanyang ka lebaka la litšila tse fapaneng. Bauxite e na le mefuta e mengata ea lisebelisoa tsa indasteri. Ka lehlakoreng le leng, ke thepa e ka sehloohong e tala bakeng sa ho hlahisa alumina, eo le eona e hlahisang aluminium. Ka lehlakoreng le leng, e sebelisoa haholo e le thepa e tala liindastering tse kang thepa ea refractory, corundum e kopantsoeng, lisebelisoa tsa ho sila, lihlahisoa tsa ceramic, lihlahisoa tsa lik'hemik'hale, le alumina slurry e phahameng.
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%.

- Indasteri ea aluminium: bauxite e na le aluminium e ngata 'me ke thepa ea bohlokoa e tala bakeng sa indasteri ea ho qhibilihisa aluminium;
2. Ho lahla ka mokhoa o nepahetseng: bauxite e ka etsoa ka mefuta e sa tšoaneng ea hlobo ea ho lahla ka mor'a ho sebetsa, haholo-holo e sebelisoang lipuisanong, lisebelisoa, mechine le liindasteri tsa thepa;
3. Lintho tse refractory: bauxite e na le lintho tse ntle tse kang ho atolosoa ha mocheso o tlaase, ho hanyetsa ho phahameng, le botsitso ba mocheso o phahameng oa mocheso, e leng se etsang hore e be ntho e tloaelehileng e tala bakeng sa thepa ea refractory. Lisebelisoa tse entsoeng ka eona li sebelisoa haholo ka tšepe, metallurgy e seng ferrous, petroleum, lik'hemik'hale le masimo a mang a indasteri.
4. Lisebelisoa tsa ho haha: phofo ea bauxite e ka ntlafatsa matla le ho tiea ha thepa e kang samente, seretse le konkreite, ha e ntse e ntlafatsa ho tšoarella ha tsona le ho hanyetsa ho bola.
