Hari ubwoko bubiri bw'ibikoresho fatizo byo gukora alumina ikora, bumwe ni "ifu yihuse" ikorwa na triallumina cyangwa ibuye rya Bayer, naho ubundi bukorwa n'umunyu wa aluminate cyangwa aluminiyumu cyangwa byombi icyarimwe.
X, ρ-alumina n'umusaruro wa X, ρ-alumina
X, ρ-alumina ni yo mashini nyamukuru ikoreshwa mu gukora utubumbe twa alumina twakozwe, cyangwa FCA mu magambo ahinnye. Mu Bushinwa, yitwa "ifu irekura vuba" bitewe n'ifu ya alumina ikorwa hakoreshejwe uburyo bwo gusukura vuba." Gusekura vuba" ni uruvange rwa X-alumina na p-alumina bifite ibikubiye bitandukanye bitewe n'imiterere itandukanye y'umusaruro.
X,ρ-alumina yavumbuwe mu 1950 kandi yemejwe na ASTM mu 1960. Mu myaka ya 1970, x no mu Burayi. Urufunguzo rw'ikoranabuhanga rya X, ρ -alumina ni ukubura amazi vuba, akenshi mu cyuma gishyushya amazi, aho ubushyuhe bw'igitanda bugenzurwa na gaze cyangwa amazi ashyushye. Mu 1975-1980, Ikigo cya Tianjin gishinzwe inganda z'ibinyabutabire cyateje imbere ikoranabuhanga ryo gusohora amazi vuba rijyanye n'ikoranabuhanga ry'Abashinwa. Cyakoresheje cyuma gishyushya amazi, cyongeramo hydroxide yumye kandi yasheshwe, kandi cyakoze uruvange rwa X-alumina na ρ-alumina binyuze mu gukaranga 0.1 ~ 10s mu itanura rishyushye vuba.
