Chidule cha Spodumene
Fomula ya molekyulu ya spodumene ndi LiAlSi2O6, kuchuluka kwake ndi 3.03 ~ 3.22 g/cm3, kuuma kwake ndi 6.5-7, kopanda maginito, kowala ngati galasi, kalasi ya Li2O ndi 8.10%, ndipo spodumene ndi yozungulira, yopyapyala kapena yofanana ndi mbale. Dongosolo la kristalo la monoclinic, mitundu yake yodziwika bwino ndi yofiirira, yobiriwira imvi, yachikasu ndi yoyera imvi. Lithium ndi chitsulo chopepuka chokhala ndi zinthu zapadera zakuthupi ndi zamakemikolo. Inkagwiritsidwa ntchito kwambiri m'makampani ankhondo m'masiku oyambirira ndipo inkaonedwa ngati chinthu chofunikira kwambiri. Pakadali pano, pali mitundu yoposa 100 ya lithiamu ndi zinthu zake. Lithium imagwiritsidwa ntchito kwambiri popanga mabatire a lithiamu amphamvu kwambiri, zowonjezera mu electrolysis ya aluminiyamu, ndi mafuta oletsa kutentha pang'ono. Kuphatikiza apo, kugwiritsa ntchito m'magawo a magalasi a ceramics, zida zamagetsi, mankhwala ndi makampani a mankhwala kukukulirakulira.
Monga mchere wolimba wa lithiamu wolemera mu lithiamu komanso wothandiza kwambiri pakupanga mchere wa lithiamu m'mafakitale, spodumene imapezeka kwambiri ku Australia, Canada, Zimbabwe, Zaire, Brazil ndi China. Migodi ya spodumene ku Xinjiang Keketuohai, Ganzi ndi Aba ku Sichuan, ndi migodi ya lepidolite ku Yichun, Jiangxi ili ndi zinthu zambiri za lithiamu. Pakadali pano ndi madera akuluakulu opangira mchere wolimba wa lithiamu ku China.
Gulu la Spodumene concentrate
Ma concentrates a Spodumene amagawidwa m'magwiritsidwe ntchito ndi ma grade osiyanasiyana. Muyezo wa ma grade a concentrates ukuwonetsedwa mu tebulo ili m'munsimu. Ma grade a concentrates akuphatikizapo magulu atatu otsatirawa: low-iron lithium concentrate, lithium concentrate ya ceramics ndi lithium concentrate ya makampani opanga mankhwala.
Njira yowonjezerera Spodumene ore
Kulekanitsidwa kwa spodumene kumakhudzidwa ndi zinthu zambiri, monga: mgwirizano wa mchere, mtundu wa kapangidwe ka miyala, ndi zina zotero, zomwe zimafuna njira zosiyanasiyana zopangira zinthu.
Kuyandama:
Kulekanitsa spodumene ndi mchere wa silicate womwe uli ndi magwiridwe ofanana a flotation ndi vuto pa njira zoyandama za spodumene kunyumba ndi kunja. Njira yoyandama ya Spodumene ikhoza kugawidwa m'njira yoyandama yobwerera m'mbuyo ndi njira yabwino yoyandama. Michere yayikulu yokhala ndi lithiamu imatha kulekanitsidwa ndi flotation, makamaka kwa spodumene yokhala ndi kapangidwe kotsika, kosalala, komanso kovuta, flotation ndi yofunika kwambiri.
Maginito kulekana:
Kupatula maginito nthawi zambiri kumagwiritsidwa ntchito kuchotsa zinyalala zokhala ndi chitsulo mu lithiamu concentrates kapena kulekanitsa iron-lepidolite yofooka ya magnetic. Pakupanga, spodumene concentrate yomwe imapezeka pogwiritsa ntchito njira yoyandama nthawi zina imakhala ndi zinyalala zambiri zokhala ndi chitsulo. Kuti muchepetse zinyalala za chitsulo, maginito olekanitsa angagwiritsidwe ntchito pochiza. Zipangizo zolekanitsa maginito ndi separator ya maginito yokhazikika ya ng'oma, separator ya maginito yolimba ya magnetic plate, ndi separator ya maginito yoyima ya vertical ring high-gradient. Ma tailings a spodumene amapangidwa makamaka ndi feldspar, ndipo olekanitsa maginito okwera kwambiri a vertical ring ndi olekanitsa maginito a slurry angagwiritsidwenso ntchito kuchotsa zinyalala kuti mupeze zinthu za feldspar zomwe zimakwaniritsa zofunikira za zipangizo za ceramic.
Wandiweyani Medium Njira:
Mu kutentha kwabwinobwino, kuchuluka kwa spodumene mu miyala ya spodumene kumakhala kwakukulu pang'ono kuposa kwa mchere wa gangue monga quartz ndi feldspar, nthawi zambiri pafupifupi 3.15 g/cm3. Kawirikawiri, miyala ya spodumene imasankhidwa pogwiritsa ntchito madzi olemera omwe ali ndi kuchuluka pakati pa kuchuluka kwa spodumene, quartz ndi feldspar, monga tribromomethane ndi tetrabromoethane. Pakati pawo, kuchuluka kwa spodumene ndi kwakukulu kuposa kwa madzi olemera awa, kotero imamira pansi ndipo imalekanitsidwa ndi mchere wa gangue monga feldspar ndi quartz.
Njira yophatikizana yopangira phindu:
Pakadali pano, n'kovuta kupeza ma lithiamu concentrates oyenerera a mchere wa lithiamu "wosauka, wabwino, komanso wosiyanasiyana" pogwiritsa ntchito njira imodzi yowonjezerera. Njira yowonjezerera iyenera kugwiritsidwa ntchito. Njira zazikulu ndi izi: njira yophatikizana yophatikizana yophatikizana yophatikizana, njira yophatikizana yophatikizana yophatikizana yophatikizana, njira yophatikizana yophatikizana yophatikizana yophatikizana, njira yophatikizana yophatikizana yophatikizana yophatikizana, njira yophatikizana yophatikizana yophatikizana yophatikizana, ndi zina zotero.
Zitsanzo za ubwino wa spodumene:
Mchere wothandiza kwambiri wa spodumene ore womwe umatumizidwa kuchokera ku Australia ndi spodumene, wokhala ndi Li2O ya 1.42%, yomwe ndi miyala ya lithiamu yapakatikati. Pali mchere wina wambiri mu miyalayi. Miyala ya gangue makamaka ndi feldspar, quartz, muscovite, ndi hematite mine ndi zina zotero.
Spodumene imayesedwa pogwiritsa ntchito kugaya, ndipo kukula kwa tinthu tomwe tasankhidwa kumayendetsedwa kufika pa -200 mesh 60-70%. Pali matope ambiri oyambira osalala bwino mu miyala yoyambirira, ndipo chlorite ndi mchere wina womwe ndi wosavuta kuusungunula panthawi yophwanya ndi kupukuta nthawi zambiri umasokoneza kwambiri kuyandama kwa miyala. Matope abwino adzachotsedwa pogwiritsa ntchito desliming operation. Kudzera mu njira yophatikizana ya maginito yolekanitsa ndi kuyandama, zinthu ziwiri, spodumene concentrate ndi feldspar concentrate, zomwe zingagwiritsidwe ntchito ngati zipangizo zopangira ceramic, zimapezeka.
