Muaj ntau ntau hom tooj dag raj extraction txoj kev, feem ntau siv nyob rau hauv kev lag luam yog siv cov electrolyte ntawm cov hlau rau extraction, txoj kev no kuj yog qhov yooj yim tshaj extraction, siab tshaj purity ntawm ib hom.
Cov khoom siv raw ntawm tooj dag raj yog tooj liab, tooj liab yuav tsim tom qab mining thiab yooj yim ua ntawm tooj liab, ua cov tooj liab rau hauv cov phaj tuab, siv nws ua cov anode ntawm electrolysis, ua ib hom nyias daim ntawv ntawm ntshiab tooj liab, raws li cathode. , muaj ntau cov kua tshuaj electrolyte, feem ntau siv yog sib tov ntawm tooj liab sulphate, muab cov hluav taws xob rau, cov tooj liab yuav decomposed rau hauv tooj liab ions, txav los ntawm lub anode mus rau cathode, thiab lwm yam, tom qab ua tiav ntawm lub hloov ntawm nws, yuav muaj electrons, thiab cov cathode yuav raug tsim nyob rau sab nraud, uas yuav tsim cov tooj liab ntshiab, uas yog qhov yooj yim tshaj plaws thiab purity siab tshaj. Nyob rau sab nraud ntawm lub cathode, cov tooj liab ntshiab yuav raug tsim, qhov no yog qhov peb hu ua electrolytic tooj liab, yog kev ua haujlwm decomposition raws li cov tshuaj theorem ntawm tooj liab.
Electrolytic tooj liab extraction yog ib tug ntau ntshiab extraction txoj kev ntawm no extracted tooj liab, manufacturing hais txog cov khoom zoo yuav zoo dua, siab purity, nws cov tshuaj lom neeg cov khoom kuj tseem ruaj khov, hom tooj liab no yog siv nyob rau hauv ib tug loj tus naj npawb ntawm cov khoom hluav taws xob. Rau qhov xav tau ntau dua ntawm cov khoom siv tooj dag, txoj kev rho tawm tooj liab tseem yuav muab qhov tseem ceeb rau kev siv txoj kev rho tawm no. Thaum lub sij hawm tag nrho cov txheej txheem rho tawm, cov impurities uas muaj cov tshuaj lom neeg qis dua piv nrog cov ntsiab lus tooj liab yuav tau muab tso rau hauv lub tank electrolysis, thiab cov khoom siv no muaj nws tus kheej ua haujlwm. Yuav kom txuag tau tus nqi ntawm cov khoom, nws yuav siv rau hauv kev tsim cov tooj dag raj.
Hais txog kev rho tawm ntawm tooj liab raws li cov khoom siv raw ntawm tooj dag raj, tam sim no, kev txhawb nqa tseem ceeb yog txoj kev electrolysis ntawm tooj liab.
