Amatafari menshi ya alumina akorwa hakoreshejwe chamotte ya bauxite nk'ibikoresho by'ibanze, bishyushwa kuri 1450-1470°C hakoreshejwe uburyo buhanitse bwo kugenzura ubuziranenge. Amatafari menshi ya alumina akorwa hakoreshejwe alumina cyangwa ibindi bikoresho by'ibanze birimo alumina nyinshi binyuze mu gushushanya no gucana. Kubera ubushobozi bwayo bwo kugabanya ubukana, alumina ishobora kurwanya aside iterwa n'isuri.
Uburyo bwo gukora amatafari ya alumina nyinshi
Hindura Chamotte uhingure ukoresheje uburyo bwo gukata amatafari ya alumina mbere yo kuyamenagura, ibi bishobora kongera ubwiza bw'amatafari ya alumina. Kubera ko hari ingano nini y'ibikomoka ku mavuta ishobora kugera kuri 90-95%. Hitamo hanyuma usuzume uburyo bwo gukata amatafari mbere yuko asya.
Amatafari ya alumina y'ubwoko butatu
Dukurikije ingano zitandukanye za Al2O3, amatafari menshi ya alumina ashobora gushyirwa mu byiciro bitatu mu Bushinwa.
Amatafari ya Alumina yo mu rwego rwa mbere afite ibipimo bya Al2O3 birenga 75%.
Amatafari ya Alumina yo mu rwego rwa kabiri afite ingano ya 60 ~ 75% ya Al2O3.
Amatafari ya Alumina yo mu rwego rwa gatatu afite ingano ya 48 ~ 60% ya Al2O3.
Ibiranga Amatafari ya Alumina menshi
Amatafari ya alumina afite imiterere myiza nko gukora neza mu bushyuhe bwinshi, kwangirika no kudashira neza, ubucucike bwinshi, icyuma gito, nibindi.

Gukoresha amatafari ya alumina nyinshi
Amatafari ya alumina ndende ashobora gukoreshwa mu itanura riturika, amatafari ashyushye, itanura rikoresha amashanyarazi. Nanone amatafari akoresha alumina ndende akoreshwa mu byuma n'ibyuma, ibidakoresha feri, ibirahure, sima, ibumba, peteroli, imashini, icyuma gishyushya, inganda z'amashanyarazi, ingufu, n'inganda za gisirikare n'ibindi.
