I-Bauxite empeleni ibhekisela ethemini elivamile le-ores engasetshenziswa embonini, ne-gibbsite, i-boehmite noma i-diaspore njengamaminerali ayinhloko.Izinkambu zayo zokusebenzisa zinezici ezimbili zensimbi nezingezona ezensimbi.I-Bauxite iyimpahla eluhlaza engcono kakhulu yokukhiqiza insimbi ye-aluminium, futhi iyinsimu yesicelo ebaluleke kakhulu.Ukusetshenziswa kwayo kubala ngaphezu kuka-90% wesamba somkhiqizo we-bauxite womhlaba.

Iyini i-bauxite?

I-Bauxite iyiminerali yobumba esetshenziswa njengempahla eyinhloko yokukhiqiza i-aluminium.Yakheka njengomkhiqizo oyinsalela ezigidini zeminyaka ngenxa yesimo sezulu samakhemikhali emadwaleni aqukethe i-aluminium silicates.Yaqala ukutholwa eFrance ngo-1821, futhi kusukela ngaleso sikhathi yatholakala ezindaweni eziningi emhlabeni jikelele.I-Ruiqifeng yakhe ubudlelwano obuqinile neGatsha lase-Guangxi le-CHALCO, engumkhiqizi omkhulu wase-China we-alumina, i-aluminium eyinhloko nemikhiqizo egayiwe ye-aluminium.

Isetshenziswa kuphi i-Bauxite?

Ukusetshenziswa okungeyona okwensimbi kwe-bauxite ikakhulukazi njengezinto ezingavuthiwe zezinto eziphikisayo, izinto ezincibilikayo, amakhemikhali kanye nosimende we-alumina ephezulu.Nakuba ingxenye ye-bauxite esetshenziswa ezintweni ezingezona ezensimbi incane, inohlu olubanzi lokusetshenziswa.Isibonelo: ngokwemikhiqizo yamakhemikhali, i-sulfate, i-trihydrate ne-aluminium chloride ingasetshenziswa ekwenzeni iphepha, ukuhlanzwa kwamanzi, i-ceramics kanye ne-petroleum refining;I-alumina ecushiwe ingasetshenziswa njenge-catalyst, catalyst carrier kanye ne-catalyst embonini yamakhemikhali, yokuhluza uwoyela kanye nemithi.I-Decolorization, ukuphelelwa amanzi emzimbeni, ukukhipha umoya, ukuqeda i-acidification, ukoma nezinye izikhangisi ezibonakalayo.

I-aluminium yensimbi iyinsimbi yesibili ebaluleke kakhulu emhlabeni, ilandela insimbi.Ngo-1995, ukusetshenziswa komhlaba ngomuntu ngamunye kwafinyelela ku-3.29kg.Ngenxa yamandla ayo adonsela phansi amancane athile, ukuqhutshwa kahle kukagesi nokushisayo, ukwenziwa kwemishini okulula nezinye izakhiwo ezinhle kakhulu, i-aluminium isetshenziswa kabanzi emikhakheni ehlukahlukene yomnotho wezwe.Njengamanje, ukusetshenziswa kwe-aluminium okukhulu kakhulu emhlabeni kusemikhakheni yezokwakha, ezokuthutha kanye neyokupakisha, okubalelwa ngaphezu kuka-60% wengqikithi yokusetshenziswa kwe-aluminium.I-Aluminium iyimpahla yokusetshenziswa engabalulekile embonini kagesi, imboni yokukhiqiza izindiza, imboni yemishini kanye nezinto ezisetshenziswa umphakathi.
