Bauxite inoreva ore inogona kushandiswa muindasitiri, uye pamwe chete inonzi ore inoumbwa negibbsite uye monohydrate semaminerari makuru.Bauxite ndiyo yakanakisa mbishi yekugadzirwa kwesimbi aruminiyamu, uye mashandisirwo ayo anodarika 90% yepasi rose inobuda.Minda yekushandiswa kwebauxite isimbi uye isiri-simbi.Kunyange zvazvo huwandu husina-simbi huri hudiki, hune huwandu hwakawanda hwekushandisa.Bauxite inoshandiswa muindasitiri yemakemikari, metallurgy, ceramics, refractory zvinhu, abrasives, adsorbents, indasitiri yemwenje, zvekuvakisa, indasitiri yemauto, nezvimwe.
Ore zvivakwa uye mineral chimiro
Bauxite musanganiswa wemaminerari akawanda (hydroxides, clay minerals, oxides, etc.) nealuminium hydroxide sechinhu chikuru.Inonziwo "bauxite" uye kazhinji inosanganisira gibbsite., Diaspore, boehmite, hematite, kaolin, opal, quartz, feldspar, pyrite uye mamwe akawanda maminerari, iyo kemikari inoumbwa iyo inonyanya kuve AI2O3, SiO2, Fe2O3, TiO2, sekondari Zvigadzirwa zvinosanganisira CaO, MgO, K2O, Na2O, S, MnO2 uye organic matter, nezvimwewo, mune chena, grey, grey-yero, yero-girini, tsvuku, brown, nezvimwe.
Beneficiation uye kucheneswa
Imwe ore yakacherwa kubva ku bauxite inogona kusangana nezvinodiwa zvekushandisa.Conventional bauxite inosarudza nzira yekubatsira zvichienderana nemhando yezvicherwa zvakabatana.Panguva imwecheteyo, kusvibiswa kunobatanidza nemaminerari ane aluminium mune mamwe mabhauxites akaoma kubvisa nemichina kana mumuviri.
01
Beneficiation classification
Iyo granular quartz jecha uye poda bauxite inogona kupatsanurwa nekugeza, sieving kana magiredhi maitiro ekuvandudza kunaka.Inokodzera boehmite ine yakakwira silicon yemukati.
02
Gravity Beneficiation
Kushandiswa kweinorema yepakati beneficiation kunogona kuparadzanisa iron-ine ivhu dzvuku mu bauxite, uye spiral concentrator inogona kubvisa siderite uye mamwe mamineral anorema.
03
Magnetic kupatsanurwa
Iko kushandiswa kweiyo isina simba remagineti kupatsanurwa kunogona kubvisa iyo magineti simbi mubauxite, uye kushandisa yakasimba magineti yekuparadzanisa michina yakadai seplate magnetic separator, vertical ring high gradient magnetic separator, electromagnetic slurry magnetic separator inogona kubvisa iron oxide, titanium uye iron silicate, etc. Kusarudzwa kwezvinhu zvisina simba zvemagineti zvinogona kuwedzera zvinyorwa zvealuminium apo kuderedza mari yekugadzirwa kwealuminium uye kugadzirisa.
04
Flotation
Kune sulfides yakadai sepyrite iri mu bauxite, xanthate flotation inogona kushandiswa kubvisa;positive and reverse flotation inogonawo kushandiswa kubvisa tsvina yakaita sepyrite, titanium, silicon, kana kusarudza AI2O3 zvirimo kusvika 73% Of high-purity bauxite.
Kugadzira alumina
Iyo Bayer process inonyanya kushandiswa kugadzira alumina kubva ku bauxite.Iyi nzira iri nyore, kushandiswa kwesimba uye mutengo wakaderera, uye mhando yechigadzirwa yakanaka.)Kune bauxite ine yakaderera reshiyo yealuminium kune silicon, iyo soda lime sintering nzira inogamuchirwa, uye nzira yeBayer uye yesoda lime sintering nzira inogona zvakare kushandiswa mumubatanidzwa wekugadzira maitiro.
Kugadzirwa kwealuminium munyu
Ne bauxite, aruminiyamu sulfate inogona kugadzirwa ne sulfuric acid nzira, uye polyaluminium chloride inogona kugadzirwa nepamusoro-temperature hydrochloric acid precipitation method.
Technical Service Scope yeHuate Beneficiation Engineering Dhizaini Institute
