Bauxite e bua ka ore e ka sebelisoang indastering, 'me ka kakaretso e bitsoa ore e entsoeng ka gibbsite le monohydrate e le liminerale tse ka sehloohong. Bauxite ke thepa e tala e ntle ka ho fetisisa bakeng sa tlhahiso ea aluminium ea tšepe, 'me tšebeliso ea eona e etsa karolo e fetang 90% ea kakaretso ea lefats'e ea bauxite. Libaka tsa ts'ebeliso ea bauxite ke tšepe le e seng tšepe. Le hoja palo ea li-non-metal e nyenyane, e na le mefuta e mengata ea tšebeliso. Bauxite e sebelisoa indastering ea lik'hemik'hale, metallurgy, ceramics, refractory, abrasives, adsorbents, indasteri ea leseli, thepa ea mohaho, indasteri ea sesole, joalo-joalo.
Thepa ea ore le sebopeho sa liminerale
Bauxite ke motsoako oa liminerale tse ngata (hydroxides, letsopa liminerale, oxides, joalo-joalo) le aluminium hydroxide e le karolo e ka sehloohong. E boetse e bitsoa "bauxite" 'me hangata e kenyelletsa gibbsite. , Diaspore, boehmite, hematite, kaolin, opal, quartz, feldspar, pyrite le liminerale tse ling tse ngata, motsoako oa lik'hemik'hale oo haholo-holo AI2O3, SiO2, Fe2O3, TiO2, secondary Thepa e kenyelletsa CaO, MgO, K2O, Na2O, S, MnO2 le lintho tse phelang, joalo-joalo, ka bosoeu, bohlooho, bohlooho-bosehla, botala bo mosehla, bo bofubelu, bo sootho, joalo-joalo.
