Ukubuka konke kwe-Spodumene
Ifomula yama-molecule ye-spodumene yi-LiAlSi2O6, ubuningi bungu-3.03 ~ 3.22 g/cm3, ubulukhuni bungu-6.5-7, akukhona okunamandla, okucwebezelayo njengengilazi, izinga lethiyori le-Li2O lingu-8.10%, kanti i-spodumene ifana nekholomu, i-granular noma i-plate. Uhlelo lwekristalu lwe-monoclinic, imibala yalo evamile i-purple, i-grey-green, iphuzi kanye ne-grey-white. I-Lithium iyinsimbi elula enezakhiwo ezikhethekile zomzimba nezamakhemikhali. Yayisetshenziswa kakhulu embonini yezempi ezinsukwini zokuqala futhi yayibhekwa njengento ewusizo. Njengamanje, kunezinhlobo ezingaphezu kwe-100 ze-lithium kanye nemikhiqizo yayo. I-Lithium isetshenziswa kakhulu ekukhiqizweni kwamabhethri e-lithium anamandla aphezulu, izithasiselo ku-electrolysis ye-aluminium, kanye nezinto zokugcoba ezingashisi kakhulu. Ngaphezu kwalokho, ukusetshenziswa emikhakheni ye-ceramics yengilazi, izinto zikagesi, imboni yezokwelapha kanye namakhemikhali nakho kuya ngokuya kuba kukhulu.
Njengeminerali eqinile ye-lithium ecebile nge-lithium futhi ewusizo kakhulu ekukhiqizweni kwezimboni kosawoti we-lithium, i-spodumene isatshalaliswa kakhulu e-Australia, eCanada, eZimbabwe, eZaire, eBrazil naseShayina. Izimayini ze-spodumene eXinjiang Keketuohai, eGanzi nase-Aba eSichuan, kanye nezimayini ze-lepidolite eYichun, eJiangxi zicebile ngemithombo ye-lithium. Njengamanje ziyizindawo eziyinhloko zokumba amaminerali e-lithium eqinile eShayina.
Ibanga lokugxilisa i-Spodumene
Ama-concentrate e-Spodumene ahlukaniswe ngokusetshenziswa okuhlukene kanye nama-grade. Izinga lamamaki okukhishwa kwe-concentrate liboniswe kuthebula elingezansi. Amamaki okukhishwa kwe-concentrate afaka izigaba ezintathu ezilandelayo: i-concentrate ye-lithium ephansi yensimbi, i-concentrate ye-lithium ye-ceramics kanye ne-concentrate ye-lithium embonini yamakhemikhali.
Indlela yokuzuza i-Spodumene ore
Ukuhlukaniswa kwe-spodumene kuthinteka yizici eziningi, njenge: i-mineral symbiosis, uhlobo lwesakhiwo se-ore, njll., okudinga izinqubo ezahlukene zokuzuza.
Ukuntanta:
Ukuhlukanisa i-spodumene namaminerali e-silicate anokusebenza okufanayo kokuntanta kuyinselele ezindleleni zokuntanta ze-spodumene ekhaya nakwamanye amazwe. Inqubo yokuntanta ye-Spodumene ingahlukaniswa ngenqubo yokuntanta ebuyela emuva kanye nenqubo yokuntanta enhle. Amaminerali ayinhloko aqukethe i-lithium angahlukaniswa ngokuntanta, ikakhulukazi kwi-spodumene enokwakheka okuphansi, okunezinhlayiya ezincane, okuyinkimbinkimbi, ukuntanta kubaluleke kakhulu.
Ukuhlukaniswa Kwamagnetic:
Ukuhlukaniswa kwamagnetic kuvame ukusetshenziselwa ukususa ukungcola okuqukethe insimbi kuma-concentrate e-lithium noma ukuhlukanisa i-iron-lepidolite ebuthakathaka. Ekwenzeni kokukhiqiza, i-spodumene concentrate etholakala ngendlela ye-flotation ngezinye izikhathi iqukethe ukungcola okwengeziwe okuqukethe insimbi. Ukuze kuncishiswe okuqukethwe kokungcola kwensimbi, ukuhlukaniswa kwamagnetic kungasetshenziswa ekwelapheni. Imishini yokuhlukaniswa kwamagnetic iyi-permanent-magnet-type magnetic separator, i-wet-type strong magnetic plate-type magnetic separator, kanye ne-vertical ring high-gradient magnetic separator. Ama-spodumene tailings akhiwe kakhulu yi-feldspar, kanti ama-vertical ring high-gradient magnetic separator kanye nama-electromagnetic slurry magnetic separator nawo angasetshenziswa ukususa ukungcola ukuthola imikhiqizo ye-feldspar ehlangabezana nezidingo zezinto zokusetshenziswa ze-ceramic.
Indlela Ephakathi Eminyene:
Ngaphansi kwezimo zokushisa ezijwayelekile, ubuningi be-spodumene ku-spodumene ore bukhulu kancane kunobamaminerali e-gangue njenge-quartz ne-feldspar, ngokuvamile cishe u-3.15 g/cm3. Ngokuvamile, i-spodumene ore ihlelwa ngokusebenzisa uketshezi olusindayo olunobuningi phakathi kobuningi be-spodumene, i-quartz ne-feldspar, njenge-tribromomethane ne-tetrabromoethane. Phakathi kwazo, ubuningi be-spodumene bukhulu kunobalezi ziphuzo ezisindayo, ngakho-ke iyacwila phansi bese ihlukaniswa namaminerali e-gangue njenge-feldspar ne-quartz.
Indlela yokuzuza ehlanganisiwe:
Njengamanje, kunzima ukuthola ama-lithium concentrates afanelekayo amaminerali e-lithium “ampofu, amahle, futhi ahlukahlukene” ngendlela eyodwa yokuzuza. Indlela yokuzuza ehlanganisiwe kumele isetshenziswe. Izinqubo eziyinhloko yilezi: ukuhlukaniswa kwe-flotation-gravity-magnetic separation combined process , inqubo ehlanganisiwe yokuhlukaniswa kwe-Flotation-magnetic, inqubo ehlanganisiwe yokwelashwa kwe-flotation-chemical, njll.
Izibonelo zokuzuza kwe-spodumene:
Iminerali ewusizo kakhulu ye-spodumene ore engeniswa e-Australia yi-spodumene, enokuqukethwe kwe-Li2O okungu-1.42%, okuyi-lithium ore yebanga eliphakathi. Kunezinye iziminerali eziningi kule ore. Iziminerali ze-gangue ikakhulukazi ziyi-feldspar, i-quartz, i-muscovite, kanye ne-hematite mine njll.
I-Spodumene ihlelwa ngokugaya, futhi usayizi wezinhlayiya ezikhethiwe ulawulwa ube yi-mesh engu-200 60-70%. Kunenqwaba yodaka oluncane oluyisisekelo ku-ore yokuqala, futhi i-chlorite namanye amaminerali okulula ukuwadaka ngesikhathi senqubo yokuchoboza nokugaya ngokuvamile azophazamisa kakhulu ukuntanta okuvamile kwe-ore. Udaka oluhle luzosuswa ngokusebenza kwe-desliming. Ngenqubo ehlanganisiwe yokuhlukaniswa kwamagnetic kanye ne-flotation, kutholakala imikhiqizo emibili, i-spodumene concentrate kanye ne-feldspar concentrate, engasetshenziswa njengezinto zokusetshenziswa ze-ceramic,.
