[I-Huate Encyclopedia of Beneficiation] Lesi sihloko sizokuthatha ukuthi uqonde indlela yokuzuza kwe-spodumene!

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 lingu-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 kuka-100 ze-lithium nemikhiqizo yayo. I-lithium isetshenziswa kakhulu ekukhiqizeni amabhethri e-lithium anamandla amakhulu, izithasiselo ku-electrolysis ye-aluminium, kanye nezithambisi ezimelana nokushisa okuphansi. Ngaphezu kwalokho, ukusetshenziswa emkhakheni wezingilazi ze-ceramics, izinto zikagesi, imboni yezokwelapha kanye namakhemikhali nakho kuya ngokuya kunwebeka.

Njengamaminerali e-lithium eqinile ecebile ku-lithium futhi ekhuthaza kakhulu ukukhiqizwa kwezimboni 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 okukhiphayo okugxilile kukhonjisiwe 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.

I-Flotation:

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 aqukethe i-lithium ayinhloko angahlukaniswa nge-flotation, ikakhulukazi i-spodumene enezinga eliphansi, ukwakheka okuhle, okuyinkimbinkimbi, ukuntanta kubaluleke kakhulu.

Ukuhlukaniswa kwamagnetic:

Ukuhlukaniswa kwamagnetic kuvame ukusetshenziselwa ukususa ukungcola okuqukethe insimbi ekugxiliseni kwe-lithium noma ukuhlukanisa i-iron-lepidolite ebuthaka. Ekwenziweni kokukhiqiza, i-spodumene concentrate etholwe ngendlela ye-flotation ngezinye izikhathi iqukethe ukungcola okunensimbi eyengeziwe. Ukunciphisa okuqukethwe kokungcola kwensimbi, ukuhlukaniswa kazibuthe kungasetshenziswa ekwelapheni. Ithuluzi lokuhlukanisa kazibuthe liyisihlukanisi esinozibuthe sohlobo lwesigubhu esihlala unomphela, isihlukanisi esinozibuthe esiqinile sohlobo oluqinile lukazibuthe, 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 kobuningi be-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: inqubo ehlanganisiwe yokuhlukaniswa kwe-flotation-gravity-magnetic separation, 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 esuka e-Australia i-spodumene, enokuqukethwe kwe-Li2O kwe-1.42%, okuyi-lithium ore yezinga eliphakathi. Kunamanye amaminerali amaningi ensimbi. Amaminerali e-ganggue ikakhulukazi i-feldspar, i-quartz, i-muscovite, ne-hematite mine 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, futhi 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 njenge-ceramic raw materials, itholakala.
