Cobalt extraction txheej txheem

Cobalt extraction txheej txheem

Cobalt ores tsis tshua muaj tshwm sim ib leeg hauv xwm. Lawv feem ntau tshwm sim hauv kev tso nyiaj npib tsib xee, tooj liab, pyrite, thiab arsenic. Cobalt thiab cov roj ntsha ua kom muaj tsawg, ua kom tsis yooj yim. Cobalt ore cov nqi uas feem ntau suav nrog Nickel- Cobalt {{{{{- bearing pyrite. Cobalt SMELTING yog tus cwj pwm los ntawm qis- cov khoom siv raw cov ntaub ntawv ntev, thiab ntau txoj kev sib tw.

Cobalt extraction los ntawm npib tsib xee, tooj liab, thiab sulfur hloov mus ntxiv thiab sulfidation smast txo los tsim cobalt alloy lossis cobalalt matter. Qhov no muaj kev sib cais los ntawm kev sib sib sib cais sib cais thiab tom qab ntawd ua rau lub siab muaj kua qaub kom tso tawm txoj kev daws teeb meem. Tom qab muaj kev huv si, kev daws teeb meem ntxiv nrog oxalic acid mus rau nag khib nyiab oxalate. Kev cais ntawm cov cobalt oxalate yields ua kom muaj kev cob haum ntawm kev cobalvale olide.

Cobalt extraction los ntawm Nickel Refining Purification Slagification Subfification Subfification ntawm Anolyte Purification Consining yog ib qho tseem ceeb raw rau cobalt extraction. Cobalt salag yog leached nrog txo cov sulfuric acid kom tso cov tshuaj raws li kev daws teeb meem sulfate. Txoj kev daws teeb meem yog tom qab ntawd yog cov namantium ferrroalite txoj kev kom tshem tawm cov hlau, thiab rho tawm kom tshem tawm impurities xws li tooj liab, thiab manganese. Txoj kev daws teeb meem tom qab sib cais los ntawm tus npib tsib xee thiab cobalt los tsim lub chlalt chloride tov, uas tuaj yeem siv los tsim cobalt oxide cov khoom los yog kom tau txais cov khoom siv nws yog cov khoom siv hluav taws xob los ntawm hluav taws xob.

Cobalt extraction los ntawm kev cobalt -} muaj pyrite: flotation}- sulfur {} {% rau 0.5% cobalt. Cobalt - sulfur mloog yog roasted nrog sulfuric acid los hloov cov txiaj ntsig zoo xws li cobalt, npib tsib xee, thiab tooj rau soluble sulfates. Roasted xuab zeb yog tom qab ntawd ua pauj nrog dej los yog acid kom hloov lub cobalt, npib tsib xee, thiab tooj mus rau hauv kev daws teeb meem. Qhov ua kom huv yog ntxuav kom tshem tawm impurities xws li hlau, tooj liab, zinc, thiab manganese. Txoj kev daws teeb meem yog cais los ntawm Nickel thiab cobalt los ua ib qho kev daws ntshav ntshiab, uas yog tom qab ntawd tau siv los tsim cov tshuab hluav taws xob hauv electrolysis.

Cobalt extraction los ntawm arsenic - Cobalt {{1} {1} {1} {1} {1}- Qhov no yog tom qab kua qaub - leached tso cov cobalt rau kev daws. Txoj kev daws teeb meem yog tshem tawm cov hlau, arsenic, thiab impurities xws li tooj liab, zinc, thiab manganese ua ntej nkag mus sib cais. Lub lim dej Cobalt yog tom qab ntawd siv los ua cov khoom siv metallic lossis cobalalt oxide cov khoom raws li kev xav tau lag luam.

Cobalt yog feem ntau cuam tshuam nrog lwm cov zaub mov thiab muaj cov khoom sib xyaw ua ke, ua rau muaj ntau cov txheej txheem cobalt smelting thiab cov txheej txheem nyuaj. Cobalt Smelting feem ntau koom nrog peb kauj ruam:

Ua ntej, hloov lub cobalt los ntawm cov ore rau hauv kev daws teeb meem, lossis npaj cov crudal cobalt alloy lossis cobalt matto, uas yog tom qab ntawd pauv mus rau hauv kev daws teeb meem;

Thib ob, kev tawm tsam kev tshem tawm thiab ua kom huv;

Thib peb, rho tawm ntawm cov hlau. Cobalt SMELTING cov txheej txheem feem ntau tuaj yeem muab faib ua plaub pawg: siab {1} {1} kub sab nrauv ua raws li los ntawm kev cob lub ntsej muag thiab cov roj thiab cov khoom noj ua si.

Cov Kev Tsim Kho Kev Tsim Kho: Siab Ua Lebring muaj cov nqi luv luv, thiab cov roj ntsha siab thiab cov nyom, ua rau muaj kev tiv thaiv ib puag ncig. Cov qauv no tau siv dav hauv cov teb chaws tsim. Kev xyaum tau ua pov thawj tias ib qho cub sib tw metall yog ib txwm muaj kev lag luam tshaj plaws, tsis hais txog cov nroj tsuag loj. Yog li ntawd, thaum lub sijhawm kho dua tshiab, ntau cov nplaim hluav taws xob tau hloov dua siab tshiab rau ib qho cub tawg. Lwm qhov yog los kawm los ntawm thiab siv ntau yam kev ua tiav, muaj kev sib zog thiab kev ua tsis tau zoo kom ua tiav kev txhim kho tas mus li.
