Litene tsa alumina tse nang le alumina e ngata bakeng sa lionto tsa ho phatloha li entsoe ka bauxite ea boemo bo holimo e le thepa e ka sehloohong e tala, e kopantsoeng ka bongata, e hatelloang, e omisoang le ho chesoa mochesong o phahameng. Ke lihlahisoa tse hanyetsang tse sebelisetsoang lionto tsa ho phatloha ka lesela.

2. Litene tse phahameng tsa alumina tse sebelisoang liontong tsa ho phatloha li hokae?
Litene tsa aluminium tse phahameng li hahiloe holim'a shaft ea sebōpi sa mollo. Shaft ea sebōpi e karolong e ka holimo ea sebōpi sa mollo. Bophara ba eona bo atoloha butle-butle ho tloha holimo ho ea tlase ho ikamahanya le katoloso ea mocheso oa tjhaja le ho fokotsa khohlano ea lebota la sebōpi holim'a tjhaja. 'Mele oa sebōpi o lula sebōping sa mollo. 50%-60% ea bophahamo bo sebetsang. Tikolohong ena, lesela la sebōpi le hloka ho fihlela litlhoko tse joalo, 'me litšobotsi tsa litene tse phahameng tsa alumina ke ho hanyetsa ho hoholo, mocheso o phahameng oa ho nolofatsa tlas'a mojaro, ho hanyetsa asiti, ho hanyetsa alkali, ho hanyetsa ho matla khoholehong ea slag, le ho hanyetsa ho tsofala hantle. E ka khotsofatsoa, kahoo e loketse haholo hore 'mele oa sebōpi sa mollo o koahetsoe ka litene tse phahameng tsa alumina.
Se boletsoeng ka holimo ke selelekela sa litene tse phahameng tsa alumina bakeng sa lionto tsa ho phatloha. Tikoloho ea lesela la onto ea ho phatloha e rarahane 'me ho na le mefuta e mengata ea thepa e hanyetsang e sebelisoang. Litene tse phahameng tsa alumina ke e 'ngoe ea tsona. Ho na le litlhaloso tse 3-5 tsa litene tse phahameng tsa alumina tse sebelisitsoeng. Litene tsa alumina tse phahameng tsa Robert li ka sebelisoa liontong tse fapaneng. Haeba ho hlokahala, ka kopo ikopanye le rona.
