Malo abwino a lepidolite pakuchotsa kwa lithiamu asinthidwa
Kutulutsa kwa lithiamu kuchokera ku mica: kutsogola kwaukadaulo, kukhala gawo lofunikira lazakudya za lithiamu
Ndi kupambana kwa lithiamu mica m'zigawo luso ndi kupita patsogolo kwa luso, lithiamu mica m'zigawo za lifiyamu wakwaniritsa lalikulu kupanga, mtengo kupanga wafika pafupifupi mtengo wa makampani lifiyamu, ndipo mankhwala ndi ndi khola, amene wakhala anazindikira ndi opanga zinthu zapamtunda za cathode.Lepidolite pang'onopang'ono yakhala gawo lofunikira lazakudya za lithiamu.
Kukula kwa lithiamu mica kwakhala chofunikira kwambiri
Kudalira kwa China pazinthu za lithiamu ndikokwera kwambiri mpaka 70%.The dziko lifiyamu chuma makamaka anagawira Chile, Australia ndi Argentina, ndi China lifiyamu gwero nkhokwe nkhani 7% yokha.Nthawi yomweyo, China ili ndi mphamvu yayikulu ya mchere wa lithiamu.Pofika chaka cha 2020, mphamvu ya lithiamu carbonate ndi lithiamu hydroxide ndi pafupifupi matani 506900 a LCE, ndipo mphamvu yapadziko lonse ya mchere wa lithiamu ndi pafupifupi matani 785700 a LCE, omwe amawerengera pafupifupi 65% yapadziko lonse lapansi.Chifukwa chake, zinthu zaku China za lithiamu zimadalira kwambiri mayiko akunja.Pafupifupi 70% ya migodi ya lithiamu imadalira kumayiko akunja, pomwe gawo la Australia limafika 60%.
Kuyambira 2018, ubale waku China Australia wayamba kuchepa pang'onopang'ono.Mu Meyi 2021, bungwe la National Development and Reform Commission lidapereka chikalata cholengeza kuyimitsidwa kwa ntchito pansi pa foni ya China Australia Strategic Economy motsogozedwa ndi madipatimenti oyenera a boma la federal la Australia, ndipo ubale waku China Australia unalowa m'mavuto.
Monga maziko a lifiyamu mphamvu zatsopano, lifiyamu chuma, lotchedwa "mafuta oyera", wakwera kwa chuma dziko China njira yosungirako chuma kuyambira 2016, ndi masuku pamutu chuma ndi kutetezedwa ndi boma.Pofuna kuthana ndi vuto la chitetezo cha lithiamu gwero lachitetezo chifukwa cha kuwonongeka kwa ubale wa China Australia, mphamvu ndi liwiro la chitukuko cha zida zamtundu wa lithiamu zitha kulimbikitsidwa.
Zida za lithiamu ku China zimakhala makamaka nyanja zamchere, spodumene ndi lepidolite.Salt Lake lifiyamu ndi 83%, makamaka kugawidwa ku Qinghai ndi Tibet;Spodumene amawerengera 15%, makamaka amagawidwa ku Sichuan;Lepidolite imakhala ndi 2%, yomwe imagawidwa ku Jiangxi.
The lithiamu m'zigawo ndondomeko ya lithiamu mica wakhala mosalekeza wokometsedwa ndi kukweza
Njira zochotsera lithiamu ku lepidolite makamaka zimaphatikizira kuwotcha laimu, kuwotcha kwa sulfuric acid, kuwotcha sulfate, kuwotcha kwa chlorination ndi kuwira kwamphamvu.
Poyerekeza ndi spodumene, lepidolite makamaka imayang'anizana ndi zonyansa zambiri mu ndondomeko yochotsa, makamaka zinthu zomwe zili ndi fluorine.Mica ilipo mu mawonekedwe a silicate ndipo imakhala yolimba kwambiri.Kumayambiriro, pamafunika kuwotcha ndi kutentha kwambiri kuti mumasulire kapangidwe ka miyala yaiwisi, kenako ndikuperanso.Kuphatikiza apo, pakapita nthawi, chinthu cha fluorine ndichosavuta kupanga hydrofluoric acid mumayendedwe, omwe amawononga zida, zomwe zimapangitsa kupanga kosalekeza.
Njira yowotcha miyala yamchere imagwiritsidwa ntchito makamaka poyambira kutulutsa kwa lithiamu kuchokera ku lepidolite.Chifukwa cha zovuta zochotsa zonyansa komanso kuchuluka kwa zinyalala zotsalira, zachotsedwa pang'onopang'ono.Pali zofunikira zambiri zokana kukana kwa zida zopangira sulfuric acid pambuyo potengera njira ya sulfuric acid, koma kukana kwa dzimbiri kwa zida zopangira sulfuric acid ndikwambiri.Pakadali pano, mabizinesi ambiri ku Yichun Area Gwiritsani ntchito njira yowotcha ya sulfate popanga.Pachiyambi choyamba, potaziyamu sulphate imagwiritsidwa ntchito kwambiri.Tsopano, sodium sulphate ndi sodium potassium sulphate amagwiritsidwa ntchito m'malo kuti achepetse mtengo wopanga.
