Bauxite inonyatso inoreva izwi rekuti ores inogona kushandiswa muindasitiri, ine gibbsite, boehmite kana diaspore semaminerari makuru.Minda yayo yekushandisa ine zvikamu zviviri zvesimbi uye isiri-simbi.Bauxite ndiyo yakanakisa mbishi yekugadzira simbi yealuminium, uye zvakare ndiyo inonyanya kukosha nzvimbo yekushandisa.Kushandiswa kwayo kunotora chikamu chinodarika makumi mapfumbamwe kubva muzana chenyika yose yebauxite inobuda.

Chii chinonzi bauxite?

Bauxite ivhu revhu rinoshandiswa seyakanyanya mbishi kugadzirwa kwealuminium.Inoumbwa sechigadzirwa chakasara pamusoro pemamiriyoni emakore nemakemikari mamiriro ekunze ematombo ane aluminium silicates.Yakatanga kuwanikwa muFrance muna 1821, uye yakabva yawanikwa munzvimbo dzakawanda pasi rose.Ruiqifeng akavaka hukama hwakasimba neGuangxi Bazi reCHALCO, inova muChina mukuru mugadziri wealumina, yekutanga aluminium uye aruminiyamu yakagadziriswa zvigadzirwa.

Bauxite inoshandiswa kupi?

Izvo zvisiri zvesimbi zvinoshandiswa zvebauxite zvinonyanya sezvimisikidzo zvezvinhu zvinoramba, zvinhu zvinoputika, makemikari uye yakakwirira alumina simende.Kunyange zvazvo chikamu chebauxite chinoshandiswa muzvinhu zvisiri zvesimbi chiri chiduku, chine zvakawanda zvekushandisa.Semuenzaniso: maererano nemishonga yemakemikari, sulfate, trihydrate uye aluminium chloride inogona kushandiswa mukugadzira mapepa, kunatswa kwemvura, ceramics uye petroleum refining;activated alumina inogona kushandiswa sechinhu chinokonzera, catalyst carrier uye catalyst mumakemikari, kunatsa mafuta uye maindasitiri emishonga.Decolorization, dehydration, degassing, deacidification, kuomesa uye zvimwe zvemuviri adsorbents.

Metal aluminium ndiyo yechipiri yakakosha simbi pasi rose, mushure mesimbi.Muna 1995, kudyiwa kwepasi rose kwakasvika 3.29kg.Nekuda kwehudiki hwayo hwesimba, yakanaka magetsi uye yekupisa conductivity, nyore machining uye zvimwe zvakawanda zvakanaka zvivakwa, aluminium inoshandiswa zvakanyanya muzvikamu zvakasiyana zvehupfumi hwenyika.Parizvino, kushandiswa kukuru kwealuminium pasi rose kuri muzvikamu zvekuvaka, zvekufambisa uye zvekurongedza, zvichiverengera kupfuura 60% yearuminiyamu yose inoshandiswa.Aluminium chinhu chakakosha paindasitiri yemagetsi, indasitiri yekugadzira ndege, indasitiri yemichina uye midziyo yevagari.
