The mankhwala zikuchokera mkulu aluminiyamu bauxite Mu mankhwala zikuchokera mkulu aluminiyamu aluminiyamu, zigawo zikuluzikulu ndi Al2O3 ndi SiO2. Mapangidwe ake amapangidwa molingana ndi kapangidwe kake ndi kugwiritsa ntchito bauxite.

Makalasi 1 mpaka 6 ndi oyenera monohydrate duralumin mtundu wa ore; Kalasi 7 ndi yoyenera zitsulo zamtundu wa aluminiyamu. Al2O3 ndiye chigawo chachikulu mu bauxite. Zomwe zili pamwamba, zimakhala bwino. Kupanga kwamakono kwa aluminiyamu yamafakitale kumafuna kuti chiŵerengero cha aluminiyumu ndi silicon sichichepera 3.0. Ma oxides ena amawonedwa ngati zonyansa. SiO2 ndi zonyansa zovulaza popanga alumina pogwiritsa ntchito njira zamchere. Kuchuluka kwa SiO2 mu bauxite kumachepetsa kupanga kwa smelting brown corundum kapena kupanga aluminiyamu yamafakitale.

TiO2 ndi Fe2O3 mu alumina bauxite wapamwamba kwambiri ndi zonyansa zazikulu ziwiri. Zomwe zili mu TiO2 zimakonda kuwonjezeka nthawi imodzi ndi kuwonjezeka kwa Al2O3. Kafukufuku wasonyeza kuti: TiO2 mu sekondale mkulu alumina bauxite makamaka ndipamene olimba njira ndi mullite, ndi kuchuluka kwa kulowa mu galasi gawo ndi yaing’ono, amene si zabwino kwa sintering wa mankhwala, koma n’kopindulitsa kusintha mkulu kutentha makina katundu wa mankhwala; Mu bauxite, TiO2 akulowa galasi gawo kwambiri, amene adzawonjezera kuchuluka kwa madzi gawo ndi kuchepetsa mamasukidwe akayendedwe a madzi gawo, amene ndi abwino kwa sintering, koma si abwino kuwongolera mkulu-kutentha ntchito ya mankhwala. The alkali zitsulo oxides K2O ndi Na2O mkulu aluminiyamu bauxite ndi amphamvu fluxes, ndipo amapanga madzi gawo pa kutentha m’munsi. Zolemba zake zikachuluka kwambiri, zidzakhudza kapangidwe kake ndi zomwe zili mu clinker ndi mankhwala, ndipo zimakhudza kwambiri ntchito ya mankhwala. Zomwe zili mu CaO mu high alumina bauxite nthawi zambiri zimakhala zotsika, pafupifupi 0.2%. Kukhalapo kwake kumawononga ntchito yotentha kwambiri ya mankhwalawa, komanso zomwe zili nazo zimakhala zochepa muzochitika zamakono.
