Pfupiso yeSpodumene
Fomura yemamorekuru yespodumene iLiAlSi2O6, huwandu hwayo huri 3.03~3.22 g/cm3, kuomarara kuri 6.5-7, kusina magineti, kupenya kwegirazi, giredhi redzidziso reLi2O i8.10%, uye spodumene yakaita secolumnar, granular kana plate-like. Monoclinic crystal system, mavara ayo akajairika ndeepepuru, grey-green, yero uye grey-white. Lithium isimbi yakareruka ine hunhu hwakakosha hwemuviri nemakemikari. Yainyanya kushandiswa muindasitiri yemauto mumazuva ekutanga uye yaionekwa sechinhu chakakosha. Parizvino, kune marudzi anopfuura 100 elithium nezvigadzirwa zvayo. Lithium inonyanya kushandiswa mukugadzira mabhatiri e lithium ane simba rakawanda, zvinowedzera mu electrolysis yealuminium, uye mafuta anodzivirira kupisa kwakaderera. Pamusoro pezvo, kushandiswa muminda yegirazi ceramics, midziyo yemagetsi, mishonga neindasitiri yemakemikari kuri kuwedzerawo.
Sechicherwa che lithium chakasimba chakapfuma mu lithium uye chinonyanya kubatsira mukugadzirwa kwemunyu we lithium mumaindasitiri, spodumene inonyanya kuwanika muAustralia, Canada, Zimbabwe, Zaire, Brazil neChina. Migodhi ye spodumene muXinjiang Keketuohai, Ganzi neAba muSichuan, uye migodhi ye lepidolite muYichun, Jiangxi yakapfuma muzviwanikwa zve lithium. Pari zvino ndiyo nzvimbo huru dzekuchera zvicherwa zve lithium chakasimba muChina.
Giredhi reSpodumene concentrate
MaSpodumene concentrates akakamurwa kuita mashandisirwo akasiyana uye mamakisi. Mwero wemakisi ekubuda kweconcentrate unoratidzwa mutafura iri pazasi. Makisi ekubuda kweconcentrate anosanganisira mapoka matatu anotevera: low-iron lithium concentrate, lithium concentrate yeceramics uye lithium concentrate yeindasitiri yemakemikari.
Nzira yekuwedzera Spodumene ore
Kuparadzaniswa kwespodumene kunokanganiswa nezvinhu zvakawanda, zvakaita se: mineral symbiosis, rudzi rwemaumbirwo esimbi, nezvimwewo, izvo zvinoda maitiro akasiyana ekuvandudza.
Kuyangarara：
Kuparadzanisa spodumene kubva kune zvicherwa zve silicate zvine mashandiro akafanana ekutenderera kwemvura kwakaoma munzira dzekufambisa spodumene kumba nekune dzimwe nyika. Maitiro ekutenderera kwemvura eSpodumene anogona kukamurwa kuita maitiro ekutenderera kwemvura uye maitiro akanaka ekutenderera kwemvura. Zvicherwa zvikuru zvine lithium zvinogona kupatsanurwa nekutenderera kwemvura, kunyanya kune spodumene ine chimiro chakaderera, chakatsetseka, chakaoma, kutenderera kwemvura kwakakosha zvikuru.
Kuparadzana kweMagineti:
Kupatsanurana kwemagineti kunowanzo shandiswa kubvisa tsvina ine iron mu lithium concentrates kana kuparadzanisa iron-lepidolite isina simba. Mukugadzira, spodumene concentrate inowanikwa nenzira yeflotation dzimwe nguva ine tsvina yakawanda ine iron. Kuti kuderedze huwandu hwetsvina yesimbi, magnetic separation inogona kushandiswa pakurapa. Midziyo yekupatsanurana yemagineti idhiramu remagetsi rinogara riripo, magnetic separator ine wet-type strong magnetic plate, uye vertical ring high-gradient magnetic separator. Ma tailings espodumene anonyanya kuumbwa nefeldspar, uye vertical ring high-gradient magnetic separators uye electromagnetic slurry magnetic separators dzinogonawo kushandiswa kubvisa tsvina kuti uwane zvigadzirwa zvefeldspar zvinosangana nezvinodiwa zvezvinhu zveceramic.
Nzira Yakakora Yepakati:
Mumamiriro ekunze ekupisa, huwandu hwespodumene mu spodumene ore hwakakura zvishoma pane hwemaminerari egangue akadai se quartz ne feldspar, kazhinji anenge 3.15 g/cm3. Kazhinji, spodumene ore inorongwa nekushandisa mvura inorema ine huwandu pakati pehuwandu hwespodumene, quartz ne feldspar, senge tribromomethane ne tetrabromoethane. Pakati padzo, huwandu hwespodumene hwakakura kupfuura hwemaminerari aya anorema, saka inonyura pasi uye inoparadzaniswa nemaminerari egangue akadai se feldspar ne quartz.
Nzira yekubatsira yakabatanidzwa:
Parizvino, zvakaoma kuwana lithium concentrates yakakodzera ye "zvicherwa zve lithium zvisina kunaka, zvakanaka, uye zvakasiyana-siyana" nenzira imwe chete yekuwedzera kunaka. Nzira yekuwedzera kunaka inofanira kushandiswa. Maitiro makuru ndeaya: flotation-gravity separation-magnetic separation combined process , Flotation-magnetic separation combined process, flotation-chemical treatment combined process, nezvimwewo.
Mienzaniso yekubatsira kwespodumene:
Chicherwa chikuru chinobatsira che spodumene ore chinotorwa kubva kuAustralia i spodumene, ine Li2O ye1.42%, inova lithium ore yepakati nepakati. Kune zvimwe zvicherwa zvakawanda muore. Zvicherwa zve gangue zvinonyanya kuve feldspar, quartz, muscovite, uye hematite mine nezvimwewo.
Spodumene inoongororwa nekukuya, uye saizi yezvikamu zvakasarudzwa inodzorwa kusvika -200 mesh 60-70%. Kune huwandu hwakawanda hwetsvina yepakutanga yakacheneswa zvakanaka mumatombo ekutanga, uye chlorite nezvimwe zvicherwa zviri nyore kunyungudika panguva yekupwanya nekukuya zvinowanzo kanganisa zvakanyanya kutenderera kwematombo kwakajairika. Madhaka matete achabviswa kuburikidza nekushanda kwekubvisa matope. Kuburikidza nemaitiro akabatanidzwa ekuparadzanisa magnetic nekuyangarara, zvigadzirwa zviviri, spodumene concentrate nefeldspar concentrate, zvinogona kushandiswa sezvinhu zveceramic, zvinowanikwa.
