Bauxite bivuga ubutare bushobora gukoreshwa mu nganda, kandi hamwe hamwe bita ubutare bugizwe na gibbsite na monohydrate nk'amabuye y'agaciro. Bauxite nigikoresho cyibanze cyiza cyo gukora aluminium metallic, kandi imikoreshereze yacyo irenga 90% yumusaruro wa bauxite ku isi. Imirima ikoreshwa ya bauxite nicyuma kandi itari icyuma. Nubwo ingano itari ibyuma ari nto, ifite uburyo bwinshi bwo gukoresha. Bauxite ikoreshwa mu nganda zikora imiti, metallurgie, ububumbyi, ibikoresho bivunika, abrasives, adsorbents, inganda zoroheje, ibikoresho byubaka, inganda za gisirikare, nibindi.
Imiterere y'ubutare n'imiterere y'amabuye y'agaciro
Bauxite ni uruvange rw'amabuye y'agaciro menshi (hydroxide, amabuye y'agaciro y'ibumba, okiside, n'ibindi) hamwe na hydroxide ya aluminium nk'ibice nyamukuru. Yitwa kandi "bauxite" kandi mubisanzwe irimo gibbsite. . MnO2 nibintu kama, nibindi, mubyera, imvi, imvi-umuhondo, umuhondo-icyatsi, umutuku, umutuku, nibindi.
Inyungu no kwezwa
Amabuye y'agaciro acukuwe muri bauxite arashobora kuzuza ibisabwa muri porogaramu. Bauxite isanzwe igena inzira yo kunguka hashingiwe kumiterere yamabuye y'agaciro yanduye. Muri icyo gihe, umwanda ujyanye na minerval irimo aluminiyumu muri bauxite zimwe na zimwe biragoye kuyikuramo mu buryo bwa tekinike cyangwa umubiri.
01
Ibyiciro by'inyungu
Umusenyi wa granular quartz hamwe nifu ya bauxite irashobora gutandukana nukwoza, gushungura cyangwa gutondekanya uburyo bwo kuzamura ireme. Irakwiriye kuri boehmite irimo silikoni nyinshi.
02
Inyungu za rukuruzi
Gukoresha inyungu ziremereye zirashobora gutandukanya ibumba ritukura ririmo ibyuma muri bauxite, kandi intumbero ya spiral irashobora gukuraho siderite nandi mabuye y'agaciro aremereye.
03
Gutandukana kwa rukuruzi
Gukoresha gutandukanya imbaraga za magnetique birashobora gukuraho icyuma cya magnetiki muri bauxite, no gukoresha ibikoresho bikomeye byo gutandukanya magnetiki nka plaque magnetiki itandukanya, impeta ya vertical ring high gradient magnetic itandukanya, electromagnetic slurry magnetic itandukanya irashobora gukuraho okiside yicyuma, titanium na silikate yicyuma, n'ibindi Guhitamo ibikoresho bya magnetiki bidakomeye birashobora kongera aluminiyumu mugihe bigabanya ikiguzi cyo gukora alumina no kuyitunganya.
04
Flotation
Kuri sulfide nka pyrite ikubiye muri bauxite, flotation ya xanthate irashobora gukoreshwa mugukuraho; flotation nziza kandi ihindagurika irashobora kandi gukoreshwa mugukuraho umwanda nka pyrite, titanium, silicon, cyangwa guhitamo AI2O3 kugeza kuri 73% bya bauxite-yera cyane.
Gukora alumina
Inzira ya Bayer ikoreshwa cyane cyane kubyara alumina kuva bauxite. Iyi nzira iroroshye, gukoresha ingufu nigiciro ni gito, kandi ubwiza bwibicuruzwa nibyiza. ). Kuri bauxite ifite igipimo gito cya aluminium na silicon, harakoreshwa uburyo bwa soda lime yo gucumura, kandi uburyo bwa Bayer hamwe nuburyo bwo gucumura soda burashobora no gukoreshwa muguhuza umusaruro.
Umusaruro wumunyu wa aluminium
Hamwe na bauxite, sulfate ya aluminiyumu irashobora gukorwa nuburyo bwa acide sulfurike, na chloride ya polyaluminiyumu irashobora gukorwa nuburyo bwo kugwa bwa hydrochloric aside yo mu bushyuhe bwo hejuru.
