Incamake ya Spodumene
Formula ya molekile ya spodumene ni LiAlSi2O6, ubucucike ni 3.03 ~ 3.22 g / cm3, ubukana ni 6.5-7, idakoresha ingufu za rukuruzi, isa n'ikirahure, urwego rw'imitekerereze ya Li2O ni 8.10%, naho spodumene ifite inkingi, granular cyangwa plate-like. Sisitemu ya kristale imwe, amabara yayo asanzwe ni umuhengeri, imvi-icyatsi, umuhondo n'umweru-ikijuju. Lithium ni icyuma cyoroshye gifite imiterere yihariye y'umubiri n'imiti. Cyakoreshwaga cyane cyane mu nganda za gisirikare mu minsi ya mbere kandi cyafatwaga nk'ikintu cy'ingenzi. Kuri ubu, hari ubwoko burenga 100 bwa lithium n'ibicuruzwa byayo. Lithium ikoreshwa cyane cyane mu gukora bateri za lithium zifite ubushobozi bwinshi, inyongera mu gukoresha electrolysis ya aluminiyumu, n'amavuta adashyuha cyane. Byongeye kandi, ikoreshwa mu bijyanye na ceramics z'ibirahure, ibikoresho by'ikoranabuhanga, ubuvuzi n'inganda za shimi nabyo birimo kwiyongera cyane.
Nk’amabuye y’agaciro ya lithiyumu akungahaye kuri lithiyumu kandi akaba yorohereza cyane mu nganda gukora umunyu wa lithiyumu, spodumene iboneka cyane muri Ositaraliya, Kanada, Zimbabwe, Zayire, Brezili n’Ubushinwa. Ibirombe bya spodumene biri muri Xinjiang Keketuohai, Ganzi na Aba muri Sichuan, hamwe n’ibirombe bya lepidolite biri muri Yichun, Jiangxi bikungahaye ku mutungo wa lithiyumu. Ubu ni byo bice by’ingenzi bicukurwamo amabuye y’agaciro ya lithiyumu mu Bushinwa.
Icyiciro cya Spodumene concective
Ibice bya Spodumene bigabanyijemo imikoreshereze n'ibyiciro bitandukanye. Igipimo ngenderwaho cy'ibice by'umusaruro w'ibice kigaragara mu mbonerahamwe iri hepfo. Ibice by'umusaruro w'ibice birimo ibyiciro bitatu bikurikira: ibice bya lithium bifite icyuma gito, ibice bya lithium bikoreshwa mu bumba na ibice bya lithium bikoreshwa mu nganda z'ubutabire.
Uburyo bwo kongerera agaciro Spodumene ore
Gutandukanya spodumene bigirwaho ingaruka n'ibintu byinshi, nko: guhuza amabuye y'agaciro, ubwoko bw'imiterere y'amabuye y'agaciro, n'ibindi, bisaba inzira zitandukanye zo kuyabyaza umusaruro.
Kureremba:
Gutandukanya spodumene n'amabuye y'agaciro afite ubushobozi bwo kuzenguruka nk'ubwa silicate ni ingorabahizi mu buryo bwo kuzenguruka spodumene mu gihugu no mu mahanga. Uburyo bwo kuzenguruka spodumene bushobora kugabanywamo inzira yo kuzenguruka inyuma n'inzira nziza yo kuzenguruka. Amabuye y'agaciro agizwe na lithium ashobora gutandukanywa no kuzenguruka, cyane cyane kuri spodumene ifite imiterere yo hasi, ifite ibice bito kandi igoye, kuzenguruka ni ingenzi cyane.
Gutandukanya magnetic:
Gutandukanya ibyuma hakoreshejwe magnetiki bikunze gukoreshwa mu gukuraho imyanda irimo icyuma mu byuma bya lithium cyangwa gutandukanya icyuma cya magnetic-lepidolite kitameze neza. Mu ikorwa, icyuma cya spodumene cyabonetse hakoreshejwe uburyo bwo kuzenguruka rimwe na rimwe kiba gifite imyanda myinshi irimo icyuma. Kugira ngo ugabanye imyanda iri mu byuma, gutandukanya ibyuma hakoreshejwe magnetiki bishobora gukoreshwa mu kuvura. Ibikoresho byo gutandukanya magnetiki ni icyuma gitandukanya ibyuma gihoraho, icyuma gitandukanya ibyuma gifite magnetic strong type magnetic type, n'icyuma gitandukanya magnetic ring high-gradient. Imyanya ya spodumene igizwe ahanini na feldspar, kandi icyuma gitandukanya ibyuma gifite vertical ring high-gradient magnetic separators na electromagnetic slurry magnetic separators nabyo bishobora gukoreshwa mu gukuraho imyanda kugira ngo haboneke ibicuruzwa bya feldspar byujuje ibisabwa ku bikoresho fatizo bya ceramic.
Uburyo buringaniye:
Mu gihe cy'ubushyuhe busanzwe, ubucucike bwa spodumene mu mabuye y'agaciro ya spodumene buruta gato ubw'amabuye y'agaciro ya gangue nka quartz na feldspar, muri rusange bungana na 3.15 g / cm3. Muri rusange, amabuye y'agaciro ya spodumene atondekwa hakoreshejwe amazi menshi afite ubucucike hagati y'ubucucike bwa spodumene, quartz na feldspar, nka tribromomethane na tetrabromoethane. Muri byo, ubucucike bwa spodumene buruta ubw'aya mazi akomeye, bityo iramanuka ijya hasi igatandukana n'amabuye y'agaciro ya gangue nka feldspar na quartz.
Uburyo bwo kubyaza umusaruro buhuriweho:
Muri iki gihe, biragoye kubona litiyumu yujuje ibisabwa ku myunyu ngugu ya litiyumu "ikennye, nziza, kandi itandukanye" hakoreshejwe uburyo bumwe bwo kuyibyaza umusaruro. Uburyo bwo kuyibyaza umusaruro bugomba gukoreshwa. Inzira z'ingenzi ni: gutandukanya imbaraga za flotation-gravity-magnetic separation combined process , gutandukanya ingufu za flotation-magnetic combined process, gutandukanya ingufu za flotation-chemical combined process, nibindi.
Ingero z'uburyo spodumene ikoreshwa:
Ubutare bw'ingenzi bw'agaciro bwa spodumene buturuka muri Ositaraliya ni spodumene, bufite Li2O ya 1.42%, ikaba ari amabuye y'agaciro ya lithium yo mu rwego rwo hagati. Hari andi mabuye menshi y'agaciro ari muri ayo mabuye. Amabuye y'agaciro ya gangue ni menshi cyane cyane feldspar, quartz, muscovite, na hematite mine n'ibindi.
Spodumene ishyirwa mu byiciro hakoreshejwe uburyo bwo gusya, kandi ingano y'uduce twatoranijwe igenzurwa kugeza kuri -200 mesh 60-70%. Hari ingano nini y'ibitaka by'ibanze bifite imiterere myiza mu mabuye y'umwimerere, kandi chlorite n'indi myunyu ngugu yoroshye gusya mu gihe cyo kuyasya no kuyasya akenshi bibangamira cyane uburyo busanzwe bwo kuzenguruka kw'amabuye y'agaciro. Icyondo gito kizakurwaho binyuze mu gikorwa cyo kuyakuraho. Binyuze mu nzira ihuriweho yo gutandukanya no kuyasya hakoreshejwe magnetism, haboneka ibintu bibiri, spodumene concentrate na feldspar concentrate, bishobora gukoreshwa nk'ibikoresho fatizo bya ceramic.
