Bauxite yerekeza ku mabuye ashobora gukoreshwa mu nganda, kandi yose hamwe yitwa amabuye agizwe na gibbsite na monohydrate nk'amabuye y'agaciro y'ingenzi. Bauxite ni yo mabuye meza cyane mu gukora aluminiyumu y'icyuma, kandi ikoreshwa ryayo rirenga 90% by'umusaruro wose wa bauxite ku isi. Inzego zikoreshwamo bauxite ni ibyuma n'ibitari ibyuma. Nubwo ingano y'amabuye atari ibyuma ari nto, ifite uburyo bwinshi bwo kuyikoresha. Bauxite ikoreshwa mu nganda za chimique, ibyuma, ibumba, ibikoresho birwanya ubushyuhe, ibintu bitera ubushyuhe, ibikoresho byoroheje, ibikoresho by'ubwubatsi, inganda za gisirikare, nibindi.
Imiterere y'amabuye y'agaciro n'imiterere y'amabuye y'agaciro
Bauxite ni uruvange rw'imyunyu ngugu myinshi (hydroxides, imyunyu ngugu y'ibumba, oxyde, nibindi) hamwe na aluminium hydroxide nk'igice cy'ingenzi. Yitwa kandi "bauxite" kandi akenshi iba irimo gibbsite. , Diaspore, boehmite, hematite, kaolin, opal, quartz, feldspar, pyrite n'indi myunyu ngugu myinshi, imiterere yayo ya shimi ikaba ahanini ari AI2O3, SiO2, Fe2O3, TiO2, secondary. Ibikubiye muri iyo myunyu ngugu birimo CaO, MgO, K2O, Na2O, S, MnO2 n'ibintu by'umwimerere, nibindi, mu cyera, imvi, imvi-umuhondo, umuhondo-icyatsi kibisi, umutuku, umukara, nibindi.
Ibyiza n'isukura
Amwe mu mabuye y’agaciro acukurwa muri bauxite ashobora kuzuza ibisabwa mu ikoreshwa ryayo. Bauxite isanzwe igena inzira yo kuyabyaza umusaruro hashingiwe ku miterere y’amabuye y’agaciro ajyanye nayo. Muri icyo gihe, imyanda ijyanye n’amabuye y’agaciro arimo aluminiyumu muri bauxite zimwe na zimwe iragoye kuyikuraho mu buryo bwa mashini cyangwa mu buryo bufatika.
01
Ishyirwa mu byiciro ry'inyungu
Umucanga wa quartz uvanze na bauxite ifu bishobora gutandukanywa hakoreshejwe uburyo bwo gukaraba, kuziba cyangwa gupima kugira ngo birusheho kuba byiza. Birakwiriye kuri boehmite ifite silikoni nyinshi.
02
Guteza imbere imbaraga zikomoka ku bunini bw'isi
Gukoresha uburyo bwo kongerera ubwiza bw’ibinyabutabire buciriritse bishobora gutandukanya ibumba ritukura ririmo icyuma riri muri bauxite, kandi icyuma gitera ubwikorezi gishobora gukuraho siderite n’indi myunyu ngugu iremereye.
03
Gutandukanya amashanyarazi n'amakuru
Gukoresha uburyo bwo gutandukanya ibintu budafite imbaraga bishobora gukuraho icyuma gikurura ibintu muri bauxite, kandi gukoresha ibikoresho bikomeye byo gutandukanya ibintu bukoresheje imbaraga nka plate magnetic separator, vertical ring high gradient magnetic separator, electromagnetic slurry magnetic separator bishobora gukuraho icyuma gikurura ibintu bukoresheje imbaraga, titaniyumu na silicate y'icyuma, nibindi. Guhitamo ibikoresho bidafite imbaraga bukoresha imbaraga bukoresha imbaraga bukoresha imbaraga bushobora kongera ingano ya aluminiyumu mu gihe bigabanya ikiguzi cyo gukora no gutunganya alumina.
04
Kureremba
Ku birebana na sulfide nka pyrite iri muri bauxite, xanthate flotation ishobora gukoreshwa mu gukuraho; flotation nziza n'iy'inyuma ishobora kandi gukoreshwa mu gukuraho imyanda nka pyrite, titanium, silicon, cyangwa guhitamo ingano ya AI2O3 kugeza kuri 73% bya bauxite yuzuye.
Gukora alumina
Uburyo bwa Bayer bukoreshwa cyane cyane mu gukora alumina ikomoka kuri bauxite. Ubu buryo bworoshye, ikoreshwa ry'ingufu n'igiciro ni bike, kandi ubwiza bw'ibicuruzwa ni bwiza. ). Kuri bauxite ifite igipimo gito cya aluminiyumu na silikoni, hakoreshwa uburyo bwo gusya soda lime, kandi uburyo bwa Bayer n'uburyo bwo gusya soda lime nabyo bishobora gukoreshwa mu buryo buhuriweho.
Gukora umunyu wa aluminiyumu
Hamwe na bauxite, sulfate ya aluminiyumu ishobora gukorwa hakoreshejwe uburyo bwa aside sulfuriki, naho polyaluminum chloride ishobora gukorwa hakoreshejwe uburyo bwa aside hydrochloric imvura ishyushye cyane.
