Gabatarwa ga ma'adinan aluminum
Ana iya fitar da ma'adinin aluminum ta hanyar amfani da ma'adinin aluminum na halitta, bauxite shine mafi mahimmanci. Ana kuma kiran ma'adinin bauxite da bauxite, babban sinadarin shine alumina oxide wanda aka shayar da shi alumina mai ɗauke da ƙazanta, ma'adinin ƙasa ne; fari ko launin toka, yana bayyana a launin ruwan kasa mai launin rawaya ko ruwan hoda saboda ƙarfen da ke cikinsa. Yawansa shine 3.9 ~ 4g/cm3, tauri 1-3, ba ya narkewa kuma yana da rauni; ba ya narkewa a cikin ruwa, yana narkewa a cikin sulfuric acid da sodium hydroxide.
Amfani da ma'adinan aluminum
Bauxite yana da wadataccen albarkatu, wanda ake buƙata ga masana'antu da yawa; saboda haka, abu ne mai matuƙar shahara wanda ba na ƙarfe ba ne, kuma dalilin da ya sa aka yi maraba da shi gabaɗaya, galibi saboda yana da matuƙar kyau a fannin masana'antu.
1. Masana'antar aluminum. Bauxite da ake amfani da shi a fannin tsaron ƙasa, sararin samaniya, motoci, wutar lantarki, sinadarai da sauran kayan yau da kullum.
2. Yin Siminti. Ana sarrafa sinadarin bauxite da aka yi da calcined zuwa foda mai laushi don yin siminti bayan an yi masa simintin, kuma ana amfani da shi a fannin soja, sararin samaniya, sadarwa, kayan aiki, injina da kayan aikin likita.
3. Don samfuran da ke hana ruwa shiga. Yawan sinadarin bauxite mai sinadarin calcium zai iya kaiwa har zuwa 1780 °C, daidaiton sinadarai, da kuma kyawawan halaye na zahiri.
4. Zaruruwan da ke hana amfani da aluminum.

Ana iya amfani da su a cikin ƙarfe da ƙarfe, masana'antar ƙarfe marasa ƙarfe, kayan lantarki, man fetur, sinadarai, sararin samaniya, makaman nukiliya, tsaron ƙasa da sauran masana'antu.
5. Ana iya amfani da sinadarin magnesia da bauxite, waɗanda aka ƙara da manne mai dacewa, don yin amfani da layin silinda na gaba ɗaya na kwalbar ƙarfe mai narkewa tare da sakamako mai kyau.
6. Ana iya yin simintin bauxite, kayan gogewa, da mahaɗan daban-daban daga bauxite na aluminum a masana'antar yumbu da masana'antar sinadarai.
