Boemo ba leano la lepidolite bakeng sa ho ntšoa ha lithium bo ntlafalitsoe
Ho ntšoa ha lithium ho tloha mica: tsoelo-pele ea theknoloji, ho fetoha karolo ea bohlokoa ea phepelo ea lisebelisoa tsa lithium
Ka katleho ea theknoloji ea ho ntša lithium mica le tsoelo-pele ea theknoloji, lithium mica extraction ea lithium e fihletse tlhahiso e kholo, theko ea tlhahiso e fihlile ho theko e tloaelehileng ea indasteri ea lithium, 'me sehlahisoa se batla se tsitsitse, se amohetsoeng ke baetsi ba thepa ea cathode e tlase.Lepidolite butle-butle e fetohile karolo ea bohlokoa ea phepelo ea lisebelisoa tsa lithium.
Nts'etsopele ea lithium mica e fetohile tlhoko ea maano
China e itšetlehile ka mehloli ea lithium e holimo ho 70%.Lisebelisoa tsa lefats'e tsa lithium li ajoa haholo-holo Chile, Australia le Argentina, 'me mehloli ea mehloli ea lithium ea Chaena e etsa karolo ea 7 feela lekholong.Ka nako e ts'oanang, Chaena e na le matla a mangata a letsoai la lithium.Ka 2020, matla a lithium carbonate le lithium hydroxide e ka ba lithane tse 506900 tsa LCE, 'me matla a lefats'e a letsoai la lithium ke lithane tse ka bang 785700 tsa LCE, tse etsang karolo ea 65% ea lefats'e.Ka hona, lisebelisoa tsa lithium tsa China li itšetlehile haholo ka linaha tse ling.Hoo e ka bang 70% ea merafo ea lithium e itšetlehile ka thepa e tsoang mose ho maoatle, eo karolo ea Australia e tsoang linaheng tse ling e fihlang ho 60%.
Ho tloha ka 2018, likamano tsa China Australia li ntse li mpefala butle-butle.Ka May 2021, Komisi ea Naha ea Ntšetso-pele le Phetoho e ile ea fana ka polelo e phatlalatsang ho emisoa ha mesebetsi e tlas'a tsamaiso ea thelefono ea moruo oa leano la China Australia ka kopanelo e etelletsoeng pele ke mafapha a amehang a mmuso oa kopanelo oa Australia, 'me likamano tsa China Australia li ile tsa kena boemong ba tsitsipano.
Joalo ka lisebelisoa tsa mantlha tsa matla a macha a lithium, lisebelisoa tsa lithium, tse tsejoang e le "oli e tšoeu", li nyolohetse ho mehloli ea polokelo ea maano ea naha ea China ho tloha ka 2016, mme ts'ebeliso ea lisebelisoa e sirelelitsoe ke mmuso.E le ho sebetsana le bothata ba tšireletso ea phepelo ea lithium e bakoang ke ho senyeha ha likamano tsa China Australia, matla le lebelo la nts'etsopele ea lisebelisoa tsa lithium tsa malapeng li ka matlafatsoa.
Lisebelisoa tsa lithium tsa China ke haholo matša a letsoai, spodumene le lepidolite.Letša la letsoai la lithium le etsa karolo ea 83%, haholo-holo e ajoang Qinghai le Tibet;Spodumene e etsa karolo ea 15%, haholo-holo e ajoang Sichuan;Lepidolite e etsa 2%, haholo-holo e ajoang Jiangxi.
Ts'ebetso ea ho ntša lithium ea lithium mica e 'nile ea ntlafatsoa le ho ntlafatsoa ka mokhoa o tsoelang pele
Mekhoa ea ho ntša lithium ho lepidolite haholo-holo e kenyelletsa ho chesa kalaka, ho halika ha sulfuric acid, roasting ea sulfate, ho chesa chlorination le khatello ea ho belisa.
Ha e bapisoa le spodumene, lepidolite haholo-holo e tobane le litšila tse ngata ts'ebetsong ea ho ntša, haholo-holo likarolo tse nang le fluorine.Mica e teng ka sebopeho sa silicate mme e na le sebopeho se batlang se le thata.Mothating oa pele, e hloka kalafo ea mocheso o phahameng oa mocheso le pheko ea defluorination ho lokolla sebopeho sa ore e tala, ebe e etsa ho sila ho latelang.Ntle le moo, mohatong oa morao, ntho ea fluorine e bonolo ho hlahisa hydrofluoric acid ts'ebetsong ea karabelo, e senyang lisebelisoa, e bakang tlhahiso e tsoelang pele.
Mokhoa oa ho chesa kalaka o sebelisoa haholo-holo mothating oa pele oa ho ntšoa ha lithium ho tloha lepidolite.Ka lebaka la ts'ebetso e rarahaneng ea ho tlosa litšila le palo e kholo ea masala a litšila, e 'nile ea felisoa butle-butle.Ho na le litlhoko tse ngata tsa ho hanyetsa kutu bakeng sa lisebelisoa tsa tlhahiso ea sulfuric acid ka mor'a hore mokhoa oa sulfuric acid o amoheloe, empa ho hanyetsa ha kutu ea lisebelisoa tsa tlhahiso ea sulfuric acid ho phahame.Hajoale, likhoebo tse ngata sebakeng sa Yichun Sebelisa mokhoa oa ho halika sa sulfate bakeng sa tlhahiso.Boemong ba pele, potassium sulfate e sebelisoa haholo-holo.Hona joale, sodium sulfate le sodium potassium sulfate li sebelisoa e le libaka tsa ho fokotsa litšenyehelo tsa tlhahiso.
