Spodumene amagqabantshintshi
I-molecular formula ye-spodumene yi-LiAlSi2O6, ubuninzi be-3.03 ~ 3.22 g / cm3, ubunzima buyi-6.5-7, i-non-magnetic, i-glassy luster, ibakala le-theory ye-Li2O yi-8.10%, kunye ne-spodumene yikholomu, i-granular okanye i-plate. -nje.Inkqubo ye-crystal ye-Monoclinic, imibala yayo eqhelekileyo imfusa, i-gray-green, i-yellow kunye ne-grey-white.I-Lithium yintsimbi ekhanyayo eneempawu ezikhethekileyo zomzimba kunye neekhemikhali.Ikakhulu yayisetyenziswa kwishishini lomkhosi ngeentsuku zokuqala kwaye yayithathwa njengento enobuchule.Okwangoku, kukho iintlobo ezingaphezu kwe-100 ze-lithium kunye neemveliso zayo.I-Lithium isetyenziswa kakhulu kwimveliso yeebhetri ze-lithium eziphezulu, izongezo kwi-electrolysis ye-aluminium, kunye nezithambisi eziphantsi kobushushu obuphantsi.Ukongeza, ukusetyenziswa kwiinkalo zeeramics zeglasi, izixhobo zombane, amayeza kunye neshishini lemichiza nalo liya likhula ngakumbi.
Njengoko i-lithium mineral eqinile ecebileyo kwi-lithium kunye neyona nto isebenzayo kwimveliso ye-lithium salts, i-spodumene isasazwa kakhulu e-Australia, eCanada, eZimbabwe, eZaire, eBrazil naseChina.Imigodi ye-spodumene e-Xinjiang Keketuohai, e-Ganzi nase-Aba e-Sichuan, kunye nemigodi ye-lepidolite e-Yichun, i-Jiangxi zizityebi kwimithombo ye-lithium.Ngoku zezona ndawo ziphambili kwimigodi ye-lithium eqinileyo yezimbiwa e-China.
Spodumene concentrate grade
I-Spodumene igxininise ihlukaniswe ngokusetyenziswa okuhlukeneyo kunye namabakala.Umgangatho wamabakala emveliso yengqwalasela ubonisiwe kwitheyibhile engezantsi.Amanqaku aphuma kugxininiso abandakanya ezi ndidi zintathu zilandelayo: i-lithium concentrate ye-iron ephantsi, i-lithium concentrate ye-ceramics kunye ne-lithium concentrate kushishino lweekhemikhali.
Spodumene ore beneficiation indlela
Ukwahlula kwe-spodumene kuchaphazeleka kwizinto ezininzi, ezifana: i-mineral symbiosis, uhlobo lwesakhiwo se-ore, njl., Okufuna iinkqubo ezahlukeneyo zokuxhamla.
Ukuphaphatheka:
Ukwahlula i-spodumene kwi-silicate minerals kunye nokusebenza okufanayo kwe-flotation kunzima kwiindlela ze-spodumene flotation ekhaya nakwamanye amazwe.Inkqubo ye-Spodumene flotation inokwahlulwa ibe yinkqubo yokubuyisela umva kunye nenkqubo efanelekileyo yokudada.Iiminerali eziphambili ze-lithium ziyakwazi ukuhlukaniswa nge-flotation, ngokukodwa kwi-spodumene enezinga eliphantsi, i-fine-grained, i-complex complex, i-flotation ibaluleke kakhulu.
Ukwahlula kwimagnethi:
Ukwahlulwa kwemagnethi ngokuqhelekileyo kusetyenziselwa ukususa ukungcola okunentsimbi kwi-lithium concentrates okanye ukwahlula i-iron-lepidolite engenamandla.Kwimveliso yokuvelisa, i-spodumene concentrate efunyenwe ngendlela ye-flotation ngamanye amaxesha iqulethe ukungcola okungaphezulu kwentsimbi.Ukunciphisa umxholo wokungcola kwentsimbi, ukuhlukana kwamagnetic kungasetyenziselwa unyango.Isixhobo sokwahlula imagnethi sisidididi-zibuthe sesahlukanisi semagnethi esisigxina, uhlobo olumanzi elomeleleyo lwepleyiti yemagnethi yohlobo lwesahlukanisi semagnethi, kunye neringi ethe nkqo enomgangatho ophezulu womahluli wemagnethi.I-spodumene tailings ikakhulu yenziwe nge-feldspar, kwaye isandi esithe nkqo i-high-gradient separators magnetic kunye ne-electromagnetic slurry separators magnetic ingasetyenziselwa ukususa ukungcola ukufumana iimveliso ze-feldspar ezihlangabezana neemfuno ze-ceramic raw materials.
Indlela exineneyo ePhakathi:
Ngaphantsi kweemeko eziqhelekileyo zokushisa, ubuninzi be-spodumene kwi-spodumene ore bukhulu kakhulu kuneeminerali ze-ganggue ezifana ne-quartz kunye ne-feldspar, ngokubanzi malunga ne-3.15 g / cm3.Ngokuqhelekileyo, i-spodumene ore ihlelwa ngokusebenzisa ulwelo olunzima kunye nokuxinana phakathi kobuninzi be-spodumene, i-quartz kunye ne-feldspar, njenge-tribromomethane kunye ne-tetrabromoethane.Phakathi kwabo, ubuninzi be-spodumene bukhulu kunolu lwamanzi anzima, ngoko lutshona phantsi kwaye luhlukaniswe kwiiminerali ze-ganggue ezifana ne-feldspar kunye ne-quartz.
Indlela yokufumana inzuzo edibeneyo:
Okwangoku, kunzima ukufumana i-lithium echanekileyo igxininise "i-lithium embi, intle, kunye ne-miscellaneous" yeeminerali ze-lithium ngendlela enye yokuzuza.Indlela yokuxhamla kufuneka isetyenziswe.Iinkqubo eziphambili zezi: i-flotation-gravity separation-magnetic separation process edityanisiweyo, inkqubo edibeneyo yokwahlukana kwe-Flotation-magnetic, inkqubo edibeneyo yonyango lwekhemikhali, njl njl.
Imizekelo yoncedo lwe-spodumene:
I-mineral ebaluleke kakhulu ye-spodumene ore evela e-Australia i-spodumene, kunye nomxholo we-Li2O we-1.42%, i-lithium ore ephakathi.Zininzi ezinye iiminerali kwintsimbi ekrwada.Iiminerali ze-ganggue ikakhulu yi-feldspar, iquartz, i-muscovite, kunye nomgodi we-hematite njl.
I-Spodumene ihlelwe ngokusila, kwaye ubukhulu be-particle ekhethiweyo ilawulwa kwi-200 mesh 60-70%.Kukho isixa esikhulu sodaka oluphambili olucolekileyo kwi-ore yokuqala, kunye nekloriyithi kunye nezinye iiminerali ekulula ukuzinyibilikisa ngexesha lokutyunyuzwa kunye nenkqubo yokusila zihlala Ziya kuphazamisa ngokunzulu ukujikeleza okuqhelekileyo kwentsimbi.Udaka olucolekileyo luya kususwa ngokucocwa.Ngokusebenzisa inkqubo edibeneyo yokuhlukana kwamagnetic kunye ne-flotation, iimveliso ezimbini, i-spodumene concentrate kunye ne-feldspar concentrate, enokusetyenziswa njenge-ceramic raw materials, ifunyenwe.
