Spodumene muchidimbu
Iyo molecular formula ye spodumene ndeye LiAlSi2O6, iyo density i3.03 ~ 3.22 g/cm3, kuomarara kuri 6.5-7, isiri-magnetic, girazi rinopenya, theoretical giredhi yeLi2O i8.10%, uye spodumene iri columnar, granular kana ndiro. -saizvozvo.Monoclinic crystal system, mavara ayo akajairika ndeepepuru, grey-girini, yero uye grey-white.Lithium isimbi yakareruka ine zvakakosha zvemuviri nemakemikari.Yainyanya kushandiswa muindasitiri yemauto mumazuva ekutanga uye yaionekwa sechinhu chakakosha.Parizvino, kune anopfuura zana marudzi e lithium uye zvigadzirwa zvayo.Lithium inonyanya kushandiswa mukugadzira mabhatiri e-high-capacity lithium, anowedzera mu electrolysis yealuminium, uye mafuta akadzikama-anodzivirira kupisa.Pamusoro pezvo, iko kushandiswa muminda yegirazi ceramics, midziyo yemagetsi, mushonga uye indasitiri yemakemikari iri kuramba ichiwedzera.
Seyakasimba lithium mineral yakawanda mu lithium uye inonyanya kukoshesa kugadzirwa kwemaindasitiri eti lithium salt, spodumene inonyanya kugoverwa muAustralia, Canada, Zimbabwe, Zaire, Brazil neChina.Migodhi ye spodumene mu Xinjiang Keketuohai, Ganzi naAba muSichuan, uye migodhi yelepidolite muYichun, Jiangxi yakapfuma mu lithium resources.Parizvino ndidzo nzvimbo huru dzekuchera yakasimba lithium zvicherwa muChina.
Spodumene concentrate giredhi
Spodumene inotarisisa yakakamurwa mukushandisa kwakasiyana uye mamakisi.Chiyero chemagiredhi eiyo concentrate inobuda inoratidzwa mutafura iri pazasi.Concentrate inobuda mamakisi anosanganisira anotevera mapoka matatu: low-iron lithium concentrate, lithium concentrate yeceramics uye lithium concentrate yemakemikari indasitiri.
Spodumene ore Beneficiation nzira
Kuparadzaniswa kwe spodumene kunokanganiswa nezvinhu zvakawanda, zvakadai se: mineral symbiosis, ore structure type, nezvimwewo, izvo zvinoda maitiro akasiyana-siyana ekubatsira.
Flotation:
Kuparadzanisa spodumene kubva kune silicate minerals ine yakafanana flotation performance inonetsa mu spodumene flotation nzira kumba nekune dzimwe nyika.Spodumene flotation process inogona kukamurwa kuita reverse flotation process uye yakanaka flotation process.Iyo huru yelithium-ine minerals inogona kuparadzaniswa ne flotation, kunyanya kune spodumene ine yakaderera-giredhi, yakanaka-grained, yakaoma kuumbwa, flotation inokosha zvikuru.
Magnetic kupatsanurwa:
Magnetic separation inowanzoshandiswa kubvisa tsvina ine iron mu lithium concentrates kana kuparadzanisa isina simba magnetic iron-lepidolite.Muchiito chekugadzira, iyo spodumene concentrate inowanikwa ne flotation nzira dzimwe nguva ine yakawanda ine iron-ine tsvina.Kuti kuderedze zviri mukati mesimbi tsvina, kupatsanurwa kwemagineti kunogona kushandiswa pakurapa.Iyo magineti yekuparadzanisa michina ndeye inogara-magineti dhiramu-mhando yemagineti separator, yakanyorova-mhando yakasimba magineti ndiro-mhando yemagineti separator, uye yakatwasuka mhete yakakwirira-gradient magineti separator.Iyo spodumene tailings inonyanya kuumbwa nefeldspar, uye vertical ring high-gradient magnetic separators uye electromagnetic slurry magnetic separators inogonawo kushandiswa kubvisa tsvina kuwana feldspar zvigadzirwa zvinosangana nezvinodiwa zveceramic raw materials.
Dense Medium Method:
Pasi pemamiriro ekunze ekupisa, kuwanda kwe spodumene mu spodumene ore yakakura zvishoma pane ye gangue minerals yakadai se quartz uye feldspar, kazhinji inenge 3.15 g / cm3.Kazhinji, spodumene ore inorongwa nekushandisa mvura inorema ine density pakati pehuwandu hwe spodumene, quartz uye feldspar, zvakadai se tribromomethane uye tetrabromoethane.Pakati pavo, kuwanda kwe spodumene yakakura kudarika yezvinwiwa izvi zvinorema, saka inonyura kusvika pasi uye inoparadzaniswa kubva kune gangue minerals yakadai sefeldspar uye quartz.
Yakasanganiswa Beneficiation nzira:
Parizvino, zvakaoma kuwana akakodzera lithium inoisa kune "varombo, yakanaka, uye yakasiyana-siyana" lithium zvicherwa nenzira imwechete yekubatsira.Iyo yakasanganiswa yekubatsira nzira inofanirwa kushandiswa.Iwo maitiro makuru ndeaya: flotation-giravhiti kupatsanurwa-magineti kupatsanurwa kwakasanganiswa maitiro, Flotation-magineti kuparadzaniswa kwakasanganiswa maitiro, flotation-kemikari kurapwa kwakasanganiswa maitiro, nezvimwe.
Mienzaniso ye spodumene beneficiation:
Iyo yakakosha mineral mineral ye spodumene ore inotengeswa kubva kuAustralia is spodumene, ine Li2O inokwana 1.42%, iyo inonzi medium-grade lithium ore.Kune mamwe akawanda mamineral mu ore.Iyo gangue zvicherwa zvakanyanya feldspar, quartz, muscovite, uye hematite mine nezvimwe.
Spodumene inogadziriswa nekukuya, uye iyo yakasarudzwa particle size inodzorwa kusvika -200 mesh 60-70%.Kune huwandu hukuru hwekutanga hwakatsetseka-grained sludge mune yepakutanga ore, uye chlorite nemamwe maminerari ayo ari nyore kusevha panguva yekupwanya nekukuya maitiro anowanzo Ichakanganisa zvakanyanya neyakajairwa kutenderera kweore.Madhaka akanaka achabviswa kuburikidza nekuita desliming operation.Kuburikidza neyakasanganiswa nzira yekuparadzaniswa kwemagineti uye kuyerera, zvigadzirwa zviviri, spodumene concentrate uye feldspar concentrate, inogona kushandiswa seceramic raw materials, inowanikwa.
