Chaw tsim tshuaj paus muag tooj liab Ingots 99.999% Ntshiab Copper Ingots

Thaum peb sau tooj liab ore thiab tom qab ntawd siv cov txuj ci smelting ntawm mining los ua tooj liab ore rau hauv tooj liab ingots Electrolytic purification ntawm tooj liab: blister tooj liab (muaj 99% tooj liab) yog ua ntej ua rau hauv daim hlau tuab li anodes, thiab cov tooj liab ntshiab yog ua rau nyias. Raws li cov cathode, sib tov ntawm sulfuric acid (H2SO4) thiab tooj liab sulfate (CuSO4) yog siv los ua cov electrolyte.Tom qab hluav taws xob, tooj liab dissolves ntawm lub anode mus rau hauv tooj liab ions (Cu) thiab txav mus rau cathode.Tom qab ncav lub cathode, electrons tau txais thiab ntshiab tooj liab (tseem hu ua electrolytic tooj liab) yog precipitated ntawm lub cathode.Cov impurities hauv blister tooj liab, xws li hlau thiab zinc, uas muaj zog tshaj tooj liab, yuav yaj ua ke nrog tooj liab li ions (Zn thiab Fe).
Piv nrog rau tooj liab ions, cov ions no tsis yooj yim rau precipitated, tsuav yog tias qhov sib txawv muaj peev xwm raug kho kom zoo thaum lub sij hawm electrolysis, nag lossis daus ntawm cov ions ntawm lub anode tuaj yeem zam tau.Cov impurities tsawg dua reactive dua tooj liab, xws li kub thiab nyiaj, yog tso rau hauv qab ntawm tes.Cov phaj tooj liab uas ua rau hauv txoj kev no yog hu ua "electrolytic tooj liab" los ntawm Jiangxi Jinhui Copper Industry Co., Ltd., uas yog cov khoom zoo thiab tuaj yeem siv los ua cov khoom siv hluav taws xob.Cov sediment tso rau hauv qab ntawm lub xovtooj ntawm electrolytic hu ua "anode slime", uas yog nplua nuj nyob rau hauv kub thiab nyiaj, uas yog heev muaj nuj nqis, thiab muaj nyiaj txiag tsis tshua muaj nqi thaum muab tawm thiab reprocessed.
