Isikhundla sobuchule se-lepidolite sokukhutshwa kwe-lithium siphuculwe
Ukukhutshwa kwe-lithium kwi-mica: ukuphumelela kwezobuchwepheshe, ukuba yinxalenye ebalulekileyo ye-lithium resource supply
Ngokuphumelela kweteknoloji ye-lithium mica extraction kunye nenkqubela phambili yetekhnoloji, i-lithium mica extraction ye-lithium ifezekise imveliso enkulu, ixabiso lemveliso lifikelele kwiindleko eziqhelekileyo ze-lithium industry, kwaye imveliso izinzileyo, eye yaqatshelwa. abavelisi bemathiriyeli yecathode esezantsi.I-Lepidolite iye ngokuthe ngcembe ibe yinxalenye ebalulekileyo ye-lithium resource supply.
Ukuphuhliswa kwe-lithium mica kuye kwaba yimfuno yeqhinga
Ukuxhomekeka kweTshayina kwimithombo ye-lithium kuphezulu njenge-70%.Imithombo yehlabathi ye-lithium isasazwa ikakhulu eChile, e-Australia naseArgentina, kwaye i-China ye-lithium yokugcina i-akhawunti ye-7% kuphela.Ngelo xesha, iChina inomthamo omkhulu wetyuwa ye-lithium.Ngo-2020, umthamo we-lithium carbonate kunye ne-lithium hydroxide malunga neetoni ze-506900 ze-LCE, kunye nomthamo wehlabathi we-lithium ityuwa malunga neetoni ze-785700 ze-LCE, zibalwa malunga ne-65% yehlabathi.Ke ngoko, izixhobo ze-lithium zaseTshayina zixhomekeke kakhulu kumazwe angaphandle.Malunga ne-70% yemigodi ye-lithium ixhomekeke ekuthengisweni kumazwe angaphandle, apho i-Australia ingenisa i-60%.
Ukusukela ngo-2018, ubudlelwane base-China e-Australia buye bawohloka ngokuthe ngcembe.NgoMeyi 2021, iKomishoni yoPhuhliso kunye noHlaziyo lwesizwe yakhupha ingxelo ebhengeza ukunqunyanyiswa kwemisebenzi phantsi kwenkqubo yefowuni ye-China Australia yeqhinga loqoqosho ngokudibeneyo ekhokelwa ngamasebe afanelekileyo karhulumente wobumbano wase-Australia, kunye nobudlelwane base-Australia base-China bangena kwimeko yoxinzelelo.
Njengoko izinto ezingundoqo ze-lithium yamandla amatsha, izibonelelo ze-lithium, ezaziwa ngokuba yi "oyile emhlophe", inyukele kwimithombo yogcino lweqhinga yesizwe yaseTshayina ukusukela ngo-2016, kwaye ukusetyenziswa kwemithombo kukhuselwe ngurhulumente.Ukuze ujongane nengxaki yokhuseleko lokubonelela nge-lithium okubangelwa ukuwohloka kobudlelwane base-China e-Australia, ukuqina kunye nesantya sophuhliso lwasekhaya lwe-lithium lunokomelezwa.
Imithombo ye-lithium yaseChina ininzi yamachibi etyuwa, i-spodumene kunye ne-lepidolite.I-Salt Lake lithium i-akhawunti ye-83%, isasazwa ikakhulu eQinghai naseTibet;I-Spodumene i-akhawunti ye-15%, isasazwa kakhulu eSichuan;I-akhawunti ye-Lepidolite ye-2%, isasazwa ikakhulu eJiangxi.
Inkqubo yokukhutshwa kwe-lithium ye-lithium mica iye yaphuculwa ngokuqhubekayo kwaye yaphuculwa
Iindlela zokukhupha i-lithium kwi-lepidolite ikakhulu zibandakanya ukutshisa i-lime, i-sulfuric acid roasting, i-sulfate roasting, i-chlorination yokugcoba kunye nokubilisa uxinzelelo.
Xa kuthelekiswa ne-spodumene, i-lepidolite ijongene ikakhulu nokungcola ngakumbi kwinkqubo yokukhutshwa, ngokukodwa izinto ezine-fluorine.I-Mica ikhona kwimo ye-silicate kwaye inokwakheka okuqinileyo.Kwinqanaba lokuqala, idinga ubushushu obuphezulu bokuqhosa kunye nonyango lokutshabalalisa ukukhulula ubume obukrwada obukrwada, kwaye emva koko uqhube ukugaya okulandelayo.Ukongeza, kwinqanaba lokugqibela, i-fluorine element ilula ukuvelisa i-hydrofluoric acid kwinkqubo yokusabela, eyonakalisa izixhobo, okukhokelela kwimveliso eqhubekayo.
Indlela yokugcoba i-limestone isetyenziswa kakhulu kwinqanaba lokuqala lokukhutshwa kwe-lithium kwi-lepidolite.Ngenxa yenkqubo yokususa ukungcola okuntsonkothileyo kunye nenani elikhulu lentsalela yenkunkuma, iye yapheliswa ngokuthe ngcembe.Zininzi iimfuno zokuxhathisa umhlwa kwizixhobo zokuvelisa i-asidi yesulfuric emva kokuba yamkelwe indlela ye-asidi ye-sulfuric, kodwa ukuxhathisa kokutya kwezixhobo zokuvelisa i-asidi ye-sulfuric kuphezulu.Okwangoku, uninzi lwamashishini kwindawo yeYichun Sebenzisa indlela yokuqhotsa i-sulfate kwimveliso.Kwinqanaba lokuqala, i-potassium sulfate isetyenziswa kakhulu.Ngoku, i-sodium sulfate kunye ne-sodium potassium sulfate zisetyenziswa njengeendawo zokunciphisa ngakumbi iindleko zemveliso.
