Incamake ya Spodumene
Inzira ya molekuline ya spodumene ni LiAlSi2O6, ubucucike ni 3.03 ~ 3.22 g / cm3, ubukana ni 6.5-7, butari magnetique, ikirahure, ikirahure cya Li2O ni 8,10%, naho spodumene ni inkingi, granular cyangwa isahani -bisa. Sisitemu ya Monoclinic sisitemu, amabara yayo asanzwe ni umutuku, icyatsi-icyatsi, umuhondo nicyatsi-cyera.Litiyumu nicyuma cyoroheje gifite imiterere yihariye yumubiri na chimique. Yakoreshwaga cyane cyane mubikorwa bya gisirikare mugihe cyambere kandi byafatwaga nkibintu byingenzi. Kugeza ubu, hari ubwoko burenga 100 bwa lithium n'ibicuruzwa byayo. Litiyumu ikoreshwa cyane cyane mu gukora za bateri zifite ingufu nyinshi za lithium, inyongeramusaruro muri electrolysis ya aluminium, hamwe n’amavuta adashobora kwihanganira ubushyuhe buke. Mubyongeyeho, ikoreshwa mubijyanye nubutaka bwibirahure, ibikoresho bya elegitoroniki, ubuvuzi ninganda zikora imiti nabyo biragenda byiyongera.
Nka minerval ikomeye ya lithium ikungahaye kuri lithium kandi ifasha cyane mu nganda zikora imyunyu ngugu, spodumene ikwirakwizwa cyane muri Ositaraliya, Kanada, Zimbabwe, Zayire, Burezili n'Ubushinwa. Ibirombe bya spodumene muri Sinayi Keketuohai, Ganzi na Aba muri Sichuan, hamwe na mine ya lepidolite i Yichun, Jiangxi ikungahaye kuri lithium. Kuri ubu ni ahantu h'ingenzi mu gucukura amabuye y'agaciro ya lithium mu Bushinwa.
Icyiciro cya Spodumene
Spodumene yibanze igabanijwemo imikoreshereze itandukanye. Ibipimo byamanota yibisohoka byerekanwe mumbonerahamwe ikurikira. Ibipimo byibanda ku bicuruzwa birimo ibyiciro bitatu bikurikira: lithium yibyuma bya lithium nkeya, lithium yibanze kuri ceramics na lithium yibanda ku nganda zikora imiti.
Uburyo bwa spodumene
Gutandukana kwa spodumene bigira ingaruka kubintu byinshi, nka: amabuye y'agaciro ya sibiyose, ubwoko bw'amabuye y'agaciro, nibindi, bisaba inzira zitandukanye.
Flotation ：
Gutandukanya spodumene namabuye y'agaciro ya silikatike hamwe nibikorwa bisa na flotation nikibazo muburyo bwa spodumene flotation mugihugu ndetse no mumahanga. Inzira ya spodumene irashobora kugabanywa muburyo bwo guhinduranya ibintu hamwe nuburyo bwiza bwo guhinduranya. Amabuye y'agaciro arimo lithium arashobora gutandukanywa na flotation, cyane cyane kuri spodumene ifite urwego rwo hasi, ingano nziza, ibihimbano bigoye, flotation ni ngombwa cyane.
Gutandukana kwa rukuruzi ：
Gutandukanya magnetique bikoreshwa mugukuraho umwanda urimo fer muri lithium yibanze cyangwa gutandukanya ibyuma bya magnetiki-lepidolite. Mubikorwa byo kubyaza umusaruro, spodumene yibanze yabonetse muburyo bwa flotation rimwe na rimwe iba irimo imyanda myinshi irimo fer. Kugabanya ibirimo umwanda, gutandukanya magneti birashobora gukoreshwa mukuvura. Ibikoresho byo gutandukanya magnetiki ni itumanaho rihoraho-ryingoma yubwoko bwa magnetiki itandukanya, ubwoko bwamazi bukomeye bwa magnetiki plaque ya magnetiki itandukanya, hamwe nimpeta ihagaritse impagarike ya magnetiki itandukanya. Umurizo wa spodumene ugizwe ahanini na feldspar, kandi impeta ihagaritse impagarike yo hejuru ya magnetiki itandukanya hamwe na electromagnetic slurry magnetic itandukanya nayo irashobora gukoreshwa mugukuraho umwanda kugirango ibone ibicuruzwa bya feldspar byujuje ibisabwa kubikoresho fatizo byubutaka.
Uburyo buciriritse ：
Mugihe cy'ubushyuhe busanzwe, ubwinshi bwa spodumene mu bucukuzi bwa spodumene ni bunini cyane ugereranije n’amabuye y'agaciro ya gangue nka quartz na feldspar, muri rusange hafi 3.15 g / cm3. Mubisanzwe, ubutare bwa spodumene butondekwa hakoreshejwe amazi aremereye hamwe nubucucike buri hagati yubucucike bwa spodumene, quartz na feldspar, nka tribromomethane na tetrabromoethane. Muri byo, ubucucike bwa spodumene buruta ubw'aya mazi aremereye, bityo bukarohama hasi kandi bugatandukanywa n'amabuye y'agaciro ya gangue nka feldspar na quartz.
Uburyo bwo guhuriza hamwe inyungu ：
Kugeza ubu, biragoye kubona lisiyumu yujuje ibyangombwa bya minisiteri "ikennye, nziza, kandi itandukanye" ikoresheje uburyo bumwe bwo kunguka. Uburyo bukoreshwa hamwe bugomba gukoreshwa. Inzira nyamukuru ni: flotation-gravity itandukanya-magnetiki itandukanya hamwe, inzira ya Flotation-magnetique itandukanijwe hamwe, flotation-chimique ivura hamwe, nibindi.
Ingero z'inyungu za spodumene ：
Amabuye y'ingenzi y'amabuye y'agaciro ya spodumene yatumijwe muri Ositaraliya ni spodumene, hamwe na Li2O igizwe na 1.42%, ikaba ari lithium yo mu rwego rwo hagati. Hariho andi mabuye y'agaciro mu bucukuzi. Amabuye y'agaciro ya gangue ni feldspar, quartz, muscovite, na mine ya hematite nibindi ..
Spodumene igabanywa no gusya, kandi ingano yatoranijwe igenzurwa kugeza -200 mesh 60-70%. Hano hari umubare munini wibanze-shitingi nziza cyane mumabuye yumwimerere, na chlorite nandi mabuye y'agaciro byoroshye kuyashonga mugihe cyo kumenagura no gusya akenshi bizabangamira cyane ihindagurika risanzwe ryamabuye. Icyondo cyiza kizakurwaho binyuze mubikorwa bya desliming. Binyuze mu nzira ihuriweho yo gutandukanya magnetiki no guhinduranya, ibicuruzwa bibiri, spodumene yibanze hamwe na feldspar yibanze, bishobora gukoreshwa nkibikoresho fatizo bya ceramic.
