Peb paub tias Congo (Kub) Copper Mine muaj qhov tshwj xeeb tshaj plaws hauv ntiaj teb.Nws cov tooj liab ore feem ntau yog tooj liab cobalt oxidized rau ntawm qhov chaw.Nyob rau hauv cov nqe lus ntawm ntau thiab ntau nqis peev, cov zis ntawm ntub tooj liab refining tau nce ntxiv.
Cov txheej txheem ntub dej ntawm Congo (Gold) Copper feem ntau yog "ore leaching- extraction- electrodeposition".Thaum lub sij hawm tus txheej txheem ntawm immersion tooj liab, sulfur dioxide los yog sodium sulfate yog siv raws li ib tug txo tus neeg sawv cev rau immerse cobalt.Cov tshuaj sulfuric acid uas muaj tooj liab cobalt tsim cathode tooj liab tom qab cov tooj liab rho tawm.
Vim hais tias lub hauv paus kev lag luam hauv zos tsis muaj zog heev, tshwj tsis yog qee cov sulfuric acid, txhua yam khoom siv pabcuam yuav tsum tau xa tuaj.Yuav kom txuag tau tus nqi, feem ntau ntawm cov khoom siv cobalt uas tsim nyob rau hauv cheeb tsam yog feem ntau ua los ntawm cov txheej txheem saum toj no.Cov khoom siv roj hmab cobalt feem ntau yog siv sodium carbonate cobalt los tsim cobalt carbonate.Txawm li cas los xij, qhov qis cobalt hauv cov ntxhib cobalt carbonate yog qhov tsawg, feem ntau yog li 25%, nce tus nqi tsheb thauj mus los thiab lwm yam nqi, thiab sodium carbonate cobalt muaj ntau cov ntsev ntsev uas nyuaj rau kev daws teeb meem.Cov emissions ncaj qha yuav ua rau ib puag ncig muaj kuab paug, thiab thaum nws yuav ua rau ib puag ncig muaj kuab paug.Yog tias nws siv rau hauv lub cev ntev, nws yuav ua rau muaj ntau ntawm sodium ions hauv cov tshuaj, uas yuav cuam tshuam rau kev tsim cov tooj liab.Raws li cov cai tswj kev tiv thaiv ib puag ncig hauv cheeb tsam tau maj mam nruj, ntau lub tuam txhab tau pib kawm ntau dua kev lag luam thiab tus phooj ywg ib puag ncig cobalt ntau lawm txheej txheem.Magnesium oxidesinking cobalt technology yog ib qho ntawm cov lus qhia.
Kev tsom mus rau Congo (Kub) cov chaw tsim khoom ntub dej hauv zos, cobalt -muaj cov kua dej tawm hauv cobalt, thiab cov kua dej tshem tawm tom qab, cov txiaj ntsig ntawm magnesium oxide thiab cobalt nyob rau hauv cov xwm txheej sib txawv tau kawm.Hauv plaub teev, qhov kawg taw tes pH tus nqi yog 8.0, thiab cobalt sinking nyhuv yog siv nrog magnesium oxide pulp.Cov khoom siv cobalt hydroxide yog siab dua 36%, cobalt rov qab yog ntau dua 99%, thiab kev siv tus nqi ntawm magnesium oxide tuaj yeem ncav cuag 91%.
Recycling cobalt hlau los ntawm cobalt sulfate tov system feem ntau txais yuav ntxiv magnesium oxide muab tshuaj txhuam los tsim cov khoom cobalt hydroxide.Seb qhov concentration ntawm magnesium oxide muab tshuaj yog khaws cia ruaj khov.Qhov nce ntawm impurities nyob rau hauv cov khoom, uas cuam tshuam rau qhov zoo ntawm cov khoom, thiab tsawg concentration ntawm magnesium oxide muab tshuaj txhuam yuav ua rau ib tug txo nyob rau hauv cobalt recycling.
