Bauxite inoreva matombo anogona kushandiswa mumaindasitiri, uye pamwe chete anonzi matombo anoumbwa negibbsite nemonohydrate sezvicherwa zvikuru. Bauxite ndiyo yakanakisa pakugadzira simbi yealuminium, uye kushandiswa kwayo kunodarika 90% yehuwandu hwese hwebauxite hunowanikwa pasi rose. Nzvimbo dzekushandisa bauxite isimbi uye isiri simbi. Kunyangwe huwandu hwesimbi hushoma, hune mashandisirwo akasiyana-siyana. Bauxite inoshandiswa muindasitiri yemakemikari, simbi, ceramics, refractory materials, abrasives, adsorbents, light industry, building materials, military industry, etc.
Zvimiro zvematombo uye chimiro chezvicherwa
Bauxite musanganiswa wemaminerari akawanda (mahydroxide, mamineral evhu, maoxide, nezvimwewo) nealuminium hydroxide sechinhu chikuru. Inonziwo "bauxite" uye inowanzo sanganisira gibbsite. , Diaspore, boehmite, hematite, kaolin, opal, quartz, feldspar, pyrite nezvimwe zvicherwa zvakawanda, makemikari ayo anonyanya kuve AI2O3, SiO2, Fe2O3, TiO2, secondary. Zvinosanganiswa zvinosanganisira CaO, MgO, K2O, Na2O, S, MnO2 uye organic matter, nezvimwewo, muchena, grey, grey-yellow, yellow-green, tsvuku, brown, nezvimwewo.
Kubatsirwa uye kucheneswa
Mamwe matombo asina kucherwa anocherwa kubva mubauxite anogona kusangana nezvinodiwa zvekushandisa. Bauxite yemazuva ano ndiyo inosarudza maitiro ekugadzira zvinhu zvichibva pamhando yezvicherwa zvisina kuchena zvine chekuita nazvo. Panguva imwe chete, tsvina ine chekuita nezvicherwa zvine aruminiyamu mune mamwe mabauxite yakaoma kubvisa nemaoko kana nemaoko.
01
Kurongwa kwezvibatsiro
Jecha re quartz rine granular ne bauxite yakapfurwa zvinogona kupatsanurwa nenzira dzekusuka, kuchekerera kana kuyera kuti zviwedzere kunaka. Rakakodzera boehmite ine silicon yakawanda.
02
Kubatsira kwesimba regiravhiti
Kushandiswa kweheavy medium beneficiation kunogona kuparadzanisa ivhu dzvuku rine iron riri mubauxite, uye spiral concentrator inogona kubvisa siderite nezvimwe zvicherwa zvinorema.
03
Kupatsanurwa kwemagineti
Kushandisa kupatsanura kwemagnetic kusina simba kunogona kubvisa simbi yemagnetic iri mubauxite, uye kushandisa michina yakasimba yekupatsanura magnetic yakadai seplate magnetic separator, vertical ring high gradient magnetic separator, electromagnetic slurry magnetic separator kunogona kubvisa iron oxide, titanium uye iron silicate, nezvimwewo. Kusarudzwa kwezvinhu zvisina simba zvemagnetic kunogona kuwedzera huwandu hwealuminium ukuwo kuchideredza mutengo wekugadzira nekugadzirisa alumina.
04
Kuyangarara
Kune masulfide akadai sepyrite ari mubauxite, xanthate flotation inogona kushandiswa kubvisa; positive uye reverse flotation inogona kushandiswawo kubvisa tsvina yakaita sepyrite, titanium, silicon, kana kusarudza huwandu hweAI2O3 hunosvika 73% ye high-purity bauxite.
Kugadzira alumina
Maitiro eBayer anonyanya kushandiswa kugadzira alumina kubva kubauxite. Maitiro aya ari nyore, kushandiswa kwesimba uye mutengo wakaderera, uye mhando yechigadzirwa chakanaka. ). Kune bauxite ine chiyero chidiki chearuminiyamu nesilicon, nzira ye soda lime sintering inotorwa, uye nzira yeBayer nenzira ye soda lime sintering inogonawo kushandiswa mukugadzirwa kwakabatana.
Kugadzirwa kwemunyu wearuminiyamu
Nebauxite, aruminiyamu sulfate inogona kugadzirwa nenzira yesulfuric acid, uye polyaluminum chloride inogona kugadzirwa nenzira yehydrochloric acid precipitation inodziya zvakanyanya.
