Spodumene mwachidule
Maselo a spodumene ndi LiAlSi2O6, kachulukidwe ndi 3.03 ~ 3.22 g / cm3, kuuma kwake ndi 6.5-7, osati maginito, kuwala kwa galasi, kalasi ya Li2O ndi 8.10%, ndipo spodumene ndi columnar, granular kapena mbale. -monga. Monoclinic crystal system, mitundu yake yodziwika bwino ndi yofiirira, imvi yobiriwira, yachikasu ndi imvi-yoyera.Lithium ndi chitsulo chopepuka chokhala ndi thupi lapadera ndi mankhwala. Amagwiritsidwa ntchito makamaka m'makampani ankhondo m'masiku oyambilira ndipo amawonedwa ngati chinthu chanzeru. Pakalipano, pali mitundu yoposa 100 ya lithiamu ndi mankhwala ake. Lithiamu imagwiritsidwa ntchito makamaka popanga mabatire a lithiamu apamwamba kwambiri, zowonjezera mu electrolysis ya aluminiyamu, ndi mafuta otsika osagwira kutentha. Kuphatikiza apo, kugwiritsa ntchito pazinthu zamagalasi zamagalasi, zida zamagetsi, zamankhwala ndi mafakitale akuchulukirachulukira.
Monga mchere wolimba wa lithiamu wolemera mu lithiamu komanso wothandiza kwambiri kupanga mafakitale a mchere wa lithiamu, spodumene imagawidwa makamaka 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 ali ndi chuma cha lithiamu. Pakali pano ndi madera akuluakulu migodi olimba lithiamu mchere ku China.
Spodumene concentrate grade
Zolinga za Spodumene zimagawidwa m'magwiritsidwe osiyanasiyana ndi magiredi. Muyezo wa magiredi a kutulutsa kowukira kwawonetsedwa mu tebulo ili m'munsimu. Makasitomala otulutsa akuphatikizapo magulu atatu otsatirawa: kukhazikika kwachitsulo chachitsulo cha lithiamu, kuyika kwa lithiamu kuzinthu zadothi ndi lifiyamu kumakampani opanga mankhwala.
Spodumene ore Beneficiation njira
Kupatukana kwa spodumene kumakhudzidwa ndi zinthu zambiri, monga: mineral symbiosis, ore structure type, etc., zomwe zimafuna njira zosiyana zopindula.
Kuyandama:
Kulekanitsa spodumene ku mchere wa silicate ndi ntchito yoyandama yofanana ndizovuta mu njira zoyandama za spodumene kunyumba ndi kunja. Njira yoyandama ya Spodumene imatha kugawidwa m'njira zosinthira mozungulira komanso njira yabwino yoyandama. Mchere waukulu wa lifiyamu ukhoza kulekanitsidwa ndi kuyandama, makamaka kwa spodumene ndi otsika, opangidwa bwino, opangidwa ndi zovuta, zoyandama ndizofunikira kwambiri.
Kupatukana kwa maginito:
Kupatukana kwa maginito kumagwiritsidwa ntchito pochotsa zonyansa zomwe zimakhala ndi chitsulo mu lithiamu kapena kupatutsa mofooka maginito iron-lepidolite. Muzochita zopanga, spodumene concentrate yomwe imapezeka ndi njira yoyandama nthawi zina imakhala ndi zonyansa zambiri zokhala ndi chitsulo. Kuchepetsa zomwe zili muzitsulo zachitsulo, kupatukana kwa maginito kungagwiritsidwe ntchito pochiza. Chida cholekanitsa maginito ndi cholekanitsa chamtundu wa maginito chamtundu wa maginito, chonyowa chamtundu wamphamvu maginito olekanitsa maginito, ndi mphete yowongoka yokhala ndi maginito olekanitsa. Ma spodumene tailings makamaka amapangidwa ndi feldspar, ndipo mphete yowongoka yapamwamba-gradient separators maginito ndi electromagnetic slurry magnetic separators angagwiritsidwenso ntchito kuchotsa zonyansa kuti apeze zinthu za feldspar zomwe zimakwaniritsa zofunikira za ceramic zopangira.
Dense Wapakatikati Njira:
Pansi pa kutentha kwabwino, kuchuluka kwa spodumene mu ore spodumene ndi kwakukulu pang'ono kusiyana ndi mchere wa gangue monga quartz ndi feldspar, kawirikawiri pafupifupi 3.15 g / cm3. Kawirikawiri, ore ya spodumene imasankhidwa pogwiritsa ntchito madzi olemera omwe ali ndi kachulukidwe pakati pa spodumene, quartz ndi feldspar, monga tribromomethane ndi tetrabromoethane. Pakati pawo, kachulukidwe ka spodumene ndi wamkulu kuposa wamadzimadzi olemerawa, choncho amamira pansi ndipo amasiyanitsidwa ndi mchere wa gangue monga feldspar ndi quartz.
Njira Yophatikizira Yothandizira:
Pakali pano, n'zovuta kupeza oyenerera lithiamu imayang'ana "osauka, abwino, ndi miscellaneous" lithiamu mchere ndi njira imodzi beneficiation. Njira yophatikizira yothandizira iyenera kugwiritsidwa ntchito. Njira zazikuluzikulu ndi: flotation-gravity kupatukana-maginito kupatukana ndondomeko, Flotation-maginito kupatukana ophatikizana ndondomeko, flotation-mankhwala mankhwala kuphatikiza ndondomeko, etc.
Zitsanzo za spodumene Beneficiation:
Mchere wothandiza kwambiri wa ore wa spodumene wotumizidwa kuchokera ku Australia ndi spodumene, wokhala ndi Li2O yokhudzana ndi 1.42%, yomwe ndi yapakati-grade lithiamu ore. Mulinso mchere wina wambiri. Mafuta a gangue makamaka ndi feldspar, quartz, muscovite, ndi hematite mine etc.
Spodumene imayikidwa ndi kugaya, ndipo kukula kwa tinthu kosankhidwa kumayendetsedwa -200 mesh 60-70%. Pali unyinji wa pulayimale zabwino-grained sludge mu ore choyambirira, ndi klorite ndi mchere zina zosavuta silt pa kuphwanya ndi akupera ndondomeko zambiri Iwo kwambiri kusokoneza yachibadwa yoyandama ore. Matope abwino adzachotsedwa pogwiritsa ntchito desliming. Kupyolera mu njira yophatikizira kupatukana kwa maginito ndi kuyandama, zinthu ziwiri, spodumene concentrate ndi feldspar concentrate, zomwe zingagwiritsidwe ntchito ngati zida za ceramic, zimapezeka.
