Crude tooj liab (muaj 99% tooj liab) yog ua rau hauv ib lub phaj tuab raws li lub anode, ntshiab tooj liab yog ua rau hauv ib daim ntawv nyias raws li cathode, thiab sib tov ntawm sulfuric acid thiab tooj liab sulfate yog siv los ua cov electrolyte. Tom qab energized, tooj liab los ntawm anode yaj mus rau hauv tooj liab ions (Cu) mus rau lub cathode kom txav mus rau cathode, tom qab tuaj txog ntawm cathode kom tau cov electrons thiab precipitate ntshiab tooj liab ntawm cathode (tseem hu ua electrolytic tooj liab). Crude tooj liab impurities xws li hlau thiab zinc, uas muaj zog tshaj tooj liab, yog yaj mus rau hauv ions (Zn thiab Fe) nrog rau tooj liab. Vim tias cov ions no tsis yooj yim rau precipitate piv nrog tooj liab ions, yog li electrolysis ntev npaum li qhov tsim nyog hloov ntawm qhov sib txawv tuaj yeem zam tau hauv cathode nag lossis daus ntawm cov ions. Tshaj li tooj liab inactive impurities xws li kub thiab nyiaj tso rau hauv qab ntawm electrolyzer. Daim ntawv tooj liab uas ua rau hauv txoj kev no yog hu ua "electrolytic copper" thiab yog qhov zoo heev uas nws tuaj yeem siv los ua cov khoom siv hluav taws xob.
No.1 electrolytic tooj liab yog tus qauv tooj liab cathode. Lub teb chaws tus qauv GB/T467-1997 tus qauv cathode tooj liab, tooj liab thiab nyiaj cov ntsiab lus tsis tsawg dua 99.95%. 1 electrolytic tooj liab tooj liab (ci tooj liab): Tuam Tshoj lub teb chaws tus qauv GB5231: Tsis yog 1 electrolytic tooj liab tooj liab, (tooj liab + nyiaj) cov ntsiab lus ntawm qhov tsawg kawg nkaus tus nqi ntawm 99.95%; No. 2 electrolytic tooj liab, (tooj liab + nyiaj) cov ntsiab lus ntawm qhov tsawg kawg nkaus tus nqi ntawm 99.90%. Raws li cov kev cai ntawm kev xa khoom ntawm Shanghai Futures Exchange, cov npe tooj liab tau muab faib ua cov khoom lag luam thiab hloov pauv rau ob theem sib txawv.
Txawm koj xav taucov kav dej tooj liab, tooj liab rods ,tooj liab daim hlau, peb muaj cov khoom thiab kev txawj ntse kom tau raws li koj xav tau.
