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, ibirahuri by'ibirahure, urwego rwa theoretical ya Li2O ni 8,10%, naho spodumene ni inkingi, granular cyangwa isahani. -bisa.Sisitemu ya kristu ya monoclinike, amabara yayo asanzwe ni ibara ry'umuyugubwe, icyatsi-icyatsi, umuhondo n'icyatsi-cyera.Lithium nicyuma cyoroheje gifite imiterere yihariye yumubiri na chimique.Byakoreshwaga 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 bateri zifite ingufu nyinshi za lithium, inyongeramusaruro muri electrolysis ya aluminium, hamwe n'amavuta yo kutagira ubushyuhe buke.Mubyongeyeho, ikoreshwa mubijyanye nubutaka bwibirahure, ibikoresho bya elegitoroniki, ubuvuzi ninganda zikora imiti nabyo biragenda byiyongera.
Nka minisiteri ikomeye ya lithium ikungahaye kuri lithiyumu kandi ifasha cyane mu nganda gukora 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 igabanijwe muburyo butandukanye hamwe n amanota.Ibipimo byamanota yibisohoka byerekanwe kumeza hepfo.Ibyiciro byo gusohora ibyiciro birimo ibyiciro bitatu bikurikira: lithium yibyuma bya lithium, lithium yibanze kuri ceramics hamwe na lithium yibanda kumashanyarazi.
Uburyo bwa Spodumene
Gutandukana kwa spodumene bigira ingaruka kubintu byinshi, nka: minerval symbiose, imiterere yubutare, nibindi, bisaba inzira zitandukanye.
Flotation ：
Gutandukanya spodumene namabuye ya silikatike hamwe nibikorwa bisa na flotation nikibazo muburyo bwa spodumene flotation murugo no mumahanga.Inzira ya spodumene irashobora kugabanywa muburyo bwo guhinduranya ibintu hamwe nibikorwa byiza.Imyunyu ngugu ya lithiyumu nyamukuru irashobora gutandukanywa na flotation, cyane cyane kuri spodumene ifite urwego rwo hasi, ingano nziza, ibice bigoye, flotation ni ngombwa cyane.
Gutandukana kwa rukuruzi ：
Gutandukanya Magnetique bikoreshwa mugukuraho ibyunyunyu fer birimo intungamubiri za lithium cyangwa gutandukanya ibyuma bya magnetiki-lepidolite.Mubikorwa byo gukora, spodumene yibanze yabonetse muburyo bwa flotation rimwe na rimwe iba irimo imyanda myinshi irimo fer.Kugabanya ibirimo umwanda wicyuma, gutandukanya magnetique birashobora gukoreshwa mukuvura.Ibikoresho byo gutandukanya magnetiki ni itumanaho rihoraho-ryingoma-itandukanya ubwoko bwa magnetiki itandukanya, itose-ubwoko bukomeye bwa magnetiki itandukanya ubwoko bwa magnetiki, hamwe nimpeta ihagaritse cyane-itandukanya magnetiki.Umurizo wa spodumene ugizwe ahanini na feldspar, kandi impeta ihagaritse impagarike ya magnetiki itandukanya hamwe na electromagnetic slurry magnetic itandukanya nayo irashobora gukoreshwa mugukuraho umwanda kugirango ibone ibicuruzwa bya feldspar byujuje ibisabwa kubikoresho bya ceramic.
Uburyo buciriritse Uburyo ：
Mubihe byubushyuhe 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 burenze ubw'aya mazi aremereye, bityo bukarohama bugatandukana 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" hakoreshejwe uburyo bumwe bwo kunguka.Uburyo bukoreshwa hamwe bugomba gukoreshwa.Inzira nyamukuru nizo: flotation-gravity itandukanya-gutandukanya magnetiki inzira ihuriweho, Flotation-magnetique itandukanya inzira ihuriweho, flotation-imiti ivura hamwe, nibindi.
Ingero zo kugenerwa spodumene ：
Amabuye y'agaciro y'ingenzi ya spodumene yatumijwe muri Ositaraliya ni spodumene, hamwe na Li2O igizwe na 1.42%, ni ubutare bwa lithium yo mu rwego rwo hagati.Hariho andi mabuye y'agaciro mu bucukuzi.Amabuye y'agaciro ya gangue ni feldspar, quartz, muscovite, na hematite mine 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 kuyungurura mugihe cyo kumenagura no gusya akenshi Bizabangamira cyane ihindagurika ryamabuye asanzwe.Icyondo cyiza kizakurwaho binyuze mubikorwa bya desliming.Binyuze mu nzira ihuriweho yo gutandukanya magnetiki no guhindagurika, ibicuruzwa bibiri, spodumene yibanze hamwe na feldspar, bishobora gukoreshwa nkibikoresho fatizo bya ceramic.
