Spodumene Uhlolojikelele
Ifomula yamangqamuzana e-spodumene yi-LiAlSi2O6, ukuminyana kungu-3.03 ~ 3.22 g/cm3, ubulukhuni buyi-6.5-7, i-non-magnetic, i-glassy luster, ibanga lethiyori le-Li2O liyi-8.10%, kanti i-spodumene iyikholomu, i-granular noma ipuleti. -njengaye.I-Monoclinic crystal system, imibala yayo evamile inombala onsomi, ompunga-oluhlaza, ophuzi nompunga-omhlophe.I-Lithium iyinsimbi ekhanyayo enezici ezikhethekile zomzimba namakhemikhali.Yayisetshenziswa kakhulu embonini yezempi ezinsukwini zakuqala futhi yayithathwa njengento enamasu.Njengamanje, kunezinhlobo ezingaphezu kwe-100 ze-lithium nemikhiqizo yayo.I-lithium isetshenziswa kakhulu ekukhiqizweni kwamabhethri e-lithium anamandla amakhulu, izithasiselo ku-electrolysis ye-aluminium, nezithambisi ezimelana nokushisa okuphansi.Ngaphezu kwalokho, ukusetshenziswa emkhakheni we-ceramics yengilazi, izinto zikagesi, imboni yezokwelapha kanye namakhemikhali nakho kuya ngokuya kunwebeka.
Njengoba i-lithium yamaminerali eqinile ecebile ku-lithium futhi ingcono kakhulu ekukhiqizeni izimboni ze-lithium usawoti, i-spodumene isakazwa ikakhulukazi e-Australia, eCanada, eZimbabwe, eZaire, eBrazil naseChina.Izimayini ze-spodumene e-Xinjiang Keketuohai, e-Ganzi nase-Aba e-Sichuan, kanye nezimayini ze-lepidolite e-Yichun, e-Jiangxi zicebile ngezinsiza ze-lithium.Njengamanje ziyizindawo eziphambili zokumba amaminerali aqinile e-lithium e-China.
Spodumene gxila grade
Ukugxila kwe-Spodumene kuhlukaniswe ngokusetshenziswa okuhlukene namabanga.Izinga lamabanga e-concentrate output liboniswa kuthebula elingezansi.Amabanga okukhiphayo okugxilile ahlanganisa lezi zigaba ezintathu ezilandelayo: i-low-iron lithium concentrate, i-lithium concentrate yezitsha zobumba kanye ne-lithium concentrate yemboni yamakhemikhali.
Indlela ye-Spodumene ore beneficiation
Ukuhlukaniswa kwe-spodumene kuthinteka yizici eziningi, njenge: i-mineral symbiosis, uhlobo lwesakhiwo se-ore, njll., Okudinga izinqubo ezahlukene zokuhlomula.
Ukuntanta:
Ukuhlukanisa i-spodumene kumaminerali e-silicate ngokusebenza okufanayo kwe-flotation kunzima ezindleleni ze-spodumene flotation ekhaya nakwamanye amazwe.Inqubo ye-Spodumene flotation ingahlukaniswa ibe yinqubo ye-flotation ehlanekezelwe kanye nenqubo enhle yokuntanta.Amaminerali amakhulu aqukethe i-lithium angahlukaniswa nge-flotation, ikakhulukazi i-spodumene enezinga eliphansi, ukwakheka okuhle, okuyinkimbinkimbi, ukuntanta kubaluleke kakhulu.
Ukuhlukaniswa kwamagnetic:
Ukuhlukaniswa kwamagnetic kuvame ukusetshenziselwa ukususa ukungcola okuqukethe insimbi ku-lithium concentrates noma ukuhlukanisa i-iron-lepidolite ebuthaka.Ekukhiqizeni ukukhiqiza, ukugxila kwe-spodumene okutholwe ngendlela ye-flotation ngezinye izikhathi kuqukethe ukungcola okuningi okuqukethe insimbi.Ukunciphisa okuqukethwe kokungcola kwensimbi, ukuhlukaniswa kazibuthe kungasetshenziswa ekwelapheni.Ithuluzi lokuhlukanisa kazibuthe liyisihlukanisi esinozibuthe sohlobo lwesigubhu esihlala unomphela, isihlukanisi esiqinile sohlobo lukazibuthe esinepuleti elimanzi, kanye nesihlukanisi esime mpo esisihlukanisayo esinezinga eliphezulu sizibuthe.I-spodumene tailings ngokuyinhloko yenziwe nge-feldspar, futhi i-vertical ring high-gradient separators magnetic and electromagnetic slurry separators magnetic ingase isetshenziselwe ukususa ukungcola ukuze kutholwe imikhiqizo ye-feldspar ehlangabezana nezidingo ze-ceramic raw materials.
Indlela Emaphakathi Eminyene:
Ngaphansi kwezimo zokushisa ezivamile, ukuminyana kwe-spodumene ku-spodumene ore kukhulu kancane kunamaminerali e-ganggue njenge-quartz ne-feldspar, ngokuvamile mayelana ne-3.15 g/cm3.Ngokuvamile, i-spodumene ore ihlelwa ngokusebenzisa uketshezi olusindayo olunomthamo phakathi kwe-spodumene, i-quartz ne-feldspar, njenge-tribromomethane ne-tetrabromoethane.Phakathi kwazo, ubukhulu be-spodumene bukhulu kunalolu ketshezi olunzima, ngakho-ke lishona phansi futhi lihlukaniswe namaminerali e-ganggue njenge-feldspar ne-quartz.
Indlela yokuhlomula ehlanganisiwe:
Njengamanje, kunzima ukuthola i-lithium egxile kumaminerali e-lithium "ampofu, amahle, futhi ahlukahlukene" ngendlela eyodwa yokuzuza.Indlela yokuhlomula ehlanganisiwe kufanele isetshenziswe.Izinqubo eziyinhloko yilezi: ukuhlukaniswa kwe-flotation-gravity separation-magnetic separation inqubo ehlanganisiwe, inqubo ehlanganisiwe yokuhlukaniswa kwe-Flotation-magnetic, inqubo ehlanganisiwe yokwelashwa kwamakhemikhali e-flotation, njll.
Izibonelo zokuhlomula kwe-spodumene:
I-mineral eyinhloko ewusizo ye-spodumene ore engeniswe e-Australia i-spodumene, enokuqukethwe kwe-Li2O kwe-1.42%, okuyi-lithium ore yezinga eliphakathi.Maningi amanye amaminerali ensimbi.Amaminerali e-ganggue ikakhulukazi i-feldspar, i-quartz, i-muscovite, kanye nemayini ye-hematite njll.
I-Spodumene ihlelwa ngokugaya, futhi usayizi wezinhlayiyana okhethiwe ulawulwa ku -200 mesh 60-70%.Kunenani elikhulu le-primary fine-grained sludge ku-ore yasekuqaleni, kanti i-chlorite namanye amaminerali alula ukucwiliswa ngesikhathi sokuchotshozwa nokugaya ngokuvamile Kuzophazamisa kakhulu ukuntanta okujwayelekile kwe-ore.Udaka olucolile luzosuswa ngokusebenza kwe-desliming.Ngenqubo ehlanganisiwe yokuhlukaniswa kwamagnetic kanye ne-flotation, imikhiqizo emibili, i-spodumene concentrate kanye ne-feldspar concentrate, engasetshenziswa njengezinto zokusetshenziswa kwe-ceramic, itholakala.
