Isishwankathelo seSpodumene
Ifomula yemolekyuli ye-spodumene yiLiAlSi2O6, ubuninzi bayo yi-3.03 ~ 3.22 g/cm3, ubunzima bayo yi-6.5-7, ayinamandla, ifana neglasi, inqanaba lethiyori leLi2O yi-8.10%, kwaye i-spodumene ifana ne-columnar, i-granular okanye i-plate-like. Inkqubo yekristale ye-monoclinic, imibala yayo eqhelekileyo imfusa, ingwevu-luhlaza, ityheli kunye nengwevu-mhlophe. I-Lithium yintsimbi ekhanyayo eneempawu ezikhethekileyo zomzimba nezekhemikhali. Yayisetyenziswa kakhulu kushishino lomkhosi kwiintsuku zokuqala kwaye yayithathwa njengento enobuchule. Okwangoku, kukho iintlobo ezingaphezu kwe-100 ze-lithium kunye neemveliso zayo. I-Lithium isetyenziswa kakhulu ekuveliseni iibhetri ze-lithium ezinomthamo ophezulu, izongezo kwi-electrolysis ye-aluminium, kunye nee-lubricants ezimelana nobushushu obuphantsi. Ukongeza, ukusetyenziswa kwiinkalo ze-ceramics zeglasi, izixhobo ze-elektroniki, amayeza kunye neshishini leekhemikhali nako kuya kusanda ngakumbi.
Njengeminerali eqinileyo yelithium etyebileyo kwi-lithium kwaye iluncedo kakhulu kwimveliso yemizi-mveliso yeetyuwa ze-lithium, i-spodumene isasazwa kakhulu e-Australia, eKhanada, eZimbabwe, eZaire, eBrazil naseTshayina. Imigodi ye-spodumene eXinjiang Keketuohai, eGanzi nase-Aba eSichuan, kunye nemigodi ye-lepidolite eYichun, eJiangxi ityebile kwimithombo ye-lithium. Okwangoku zezona ndawo ziphambili zokumba iiminerali ze-lithium eqinileyo eTshayina.
Udidi lwe-Spodumene concentrate
Ii-Spodumene concentrates zahlulwe ngeendlela ezahlukeneyo zokusetyenziswa kunye nee-grades. Umgangatho wamanqanaba emveliso ye-concentrate uboniswe kwitheyibhile engezantsi. Amanqanaba emveliso ye-concentrate aquka la maqela mathathu alandelayo: i-low-iron lithium concentrate, i-lithium concentrate ye-ceramics kunye ne-lithium concentrate kwishishini leekhemikhali.
Indlela yokuphucula i-Spodumene ore
Ukwahlulwa kwe-spodumene kuchatshazelwa zizinto ezininzi, ezinje: i-mineral symbiosis, uhlobo lwesakhiwo se-ore, njl.njl., efuna iinkqubo ezahlukeneyo zokuphucula.
Ukudada:
Ukwahlula i-spodumene kwiiminerali ze-silicate ezine-flotation efanayo yingxaki kwiindlela ze-spodumene flotation ekhaya nakwamanye amazwe. Inkqubo ye-Spodumene flotation inokwahlulwa ibe yi-reverse flotation process kunye ne-positive flotation process. Iiminerali eziphambili eziqulathe i-lithium zinokwahlulwa ngokuflotation, ngakumbi kwi-spodumene enokwakheka okuphantsi, okucolekileyo, okuntsonkothileyo, i-flotation ibaluleke kakhulu.
Ukwahlukana kweMagnetic:
Ukwahlulwa kwemagnethi kudla ngokusetyenziswa ukususa ukungcola okune-iron kwi-lithium concentrates okanye ukwahlula i-iron-lepidolite ebuthathaka. Kwindlela yokuvelisa, i-spodumene concentrate efunyenwe ngendlela ye-flotation ngamanye amaxesha iqulethe ukungcola okune-iron. Ukunciphisa umxholo wokungcola kwesinyithi, ukwahlulwa kwemagnethi kungasetyenziselwa unyango. Izixhobo zokwahlulwa kwemagnethi zi-permanent-magnet drum-type separator, i-wet-type strong magnetic plate-type magnetic separator, kunye ne-vertical ring high-gradient magnetic separator. Ii-spodumene tailings zenziwe ikakhulu yi-feldspar, kwaye i-vertical ring high-gradient magnetic separators kunye ne-electromagnetic slurry magnetic separators nazo zingasetyenziselwa ukususa ukungcola ukuze kufunyanwe iimveliso ze-feldspar ezihlangabezana neemfuno zezinto eziluhlaza ze-ceramic.
Indlela Ephakathi Exineneyo:
Phantsi kweemeko zobushushu eziqhelekileyo, uxinano lwe-spodumene kwi-spodumene ore lukhulu kancinci kunolweeminerali ze-gangue ezifana ne-quartz kunye ne-feldspar, ngokubanzi malunga ne-3.15 g/cm3. Ngokubanzi, i-spodumene ore ihlelwa ngokusebenzisa ulwelo olunzima olunoxinano phakathi koxinano lwe-spodumene, i-quartz kunye ne-feldspar, njenge-tribromomethane kunye ne-tetrabromoethane. Phakathi kwazo, uxinano lwe-spodumene lukhulu kunolwelo olunzima, ngoko ke lutshona ezantsi kwaye lwahlulwe kwiiminerali ze-gangue ezifana ne-feldspar kunye ne-quartz.
Indlela yokuzuza edibeneyo:
Okwangoku, kunzima ukufumana ii-lithium concentrates ezifanelekileyo zeeminerali ze-lithium "ezimbi, ezincinci, nezingafaniyo" ngendlela enye yokuphucula. Indlela yokuphucula edibeneyo kufuneka isetyenziswe. Iinkqubo eziphambili zezi: inkqubo edibeneyo yokwahlulahlula i-flotation-gravity-magnetic separation , inkqubo edibeneyo yokwahlulahlula i-Flotation-magnetic, inkqubo edibeneyo yonyango lwe-flotation-chemical, njl.
Imizekelo yokunceda nge-spodumene:
Eyona minerali iluncedo kakhulu ye-spodumene ore engeniswe e-Australia yi-spodumene, enomxholo we-Li2O oyi-1.42%, eyi-lithium ore yezinga eliphakathi. Kukho ezinye iiminerali ezininzi kwi-ore. Iiminerali ze-gangue ikakhulu yi-feldspar, i-quartz, i-muscovite, kunye ne-hematite mine njl.
I-Spodumene ihlelwa ngokwesila, kwaye ubungakanani besuntswana olukhethiweyo bulawulwa ukuya kwi-200 mesh 60-70%. Kukho inani elikhulu le-sludge ecolekileyo yokuqala kwi-ore yokuqala, kwaye i-chlorite kunye nezinye iiminerali ezilula ukutyibilika ngexesha lenkqubo yokutyumza nokusila zihlala ziphazamisa kakhulu ukutyibilika okuqhelekileyo kwe-ore. Udaka olucolekileyo luya kususwa ngokusebenza kwe-desliming. Ngenkqubo edibeneyo yokwahlulwa kwemagnethi kunye ne-flotation, kufunyanwa iimveliso ezimbini, i-spodumene concentrate kunye ne-feldspar concentrate, ezinokusetyenziswa njengezinto eziluhlaza ze-ceramic,.
