Rea tseba hore Moepo oa Koporo oa Congo (Khauta) o na le mehloli e mengata ka ho fetisisa lefatšeng.Ore ea eona ea koporo haholo-holo ke cobalt ea koporo e nang le oxidized holim'a metsi.Mabapi le matsete a mangata, tlhahiso ea ho hloekisa koporo e metsi e eketsehile le ho feta.
Mokhoa oa tlhahiso ea metsi oa Congo (Gold) Copper ka kakaretso ke "ore leaching- extraction- electrodeposition".Nakong ea ho qoelisoa koporo, sulfur dioxide kapa sodium sulfate e sebelisoa e le ntho e fokotsang ho qoelisa cobalt.Tharollo ea sulfuric acid e nang le cobalt ea koporo e hlahisa koporo ea cathode ka mor'a hore ho ntšoa ha koporo.
Hobane motheo oa indasteri ea lehae o fokola haholo, ntle le sulfuric acid, ha e le hantle lisebelisoa tsohle tse thusang tsa indasteri li hloka ho romelloa kantle ho naha.E le ho boloka litšenyehelo, boholo ba lihlahisoa tsa cobalt tse hlahisoang sebakeng sa sebaka seo hangata li entsoe ke mokhoa o ka holimo.Metsoako e tloaelehileng ka ho fetisisa ea cobalt ke tšebeliso ea sodium carbonate cobalt ho hlahisa cobalt carbonate.Leha ho le joalo, cobalt e tlaase ea cobalt carbonate e tlaase, boholo ba eona e ka bang 25%, e eketsa litšenyehelo tsa lipalangoang le litšenyehelo tse ling, 'me sodium carbonate cobalt e na le letsoai le leholo la sodium leo ho leng thata ho sebetsana le lona.Mesi e tsoang ka kotloloho e tla baka tšilafalo ea tikoloho, 'me ha e ntse e tla baka tšilafalo ea tikoloho.Haeba e sebelisoa tsamaisong nako e telele, e tla baka palo e kholo ea li-ion tsa sodium ka tharollo, e tla ama ka ho teba tlhahiso ea koporo.Ha maano a ts'ireletso ea tikoloho a ntse a le thata butle butle, lik'hamphani tse 'maloa li se li qalile ho ithuta mekhoa ea tlhahiso ea cobalt e bolokang moruo le e se nang tikoloho.Magnesium oxidetheknoloji ea ho teba ea cobalt ke e 'ngoe ea litsela.
E lebisitse ho lifeme tsa lehae tsa Congo (Khauta) tse qhibilihisang metsi, cobalt e nang le metsi a koporo a cobalt, le lino tse tsoang ka morao, phello ea magnesium oxide le cobalt tlasa maemo a fapaneng e ile ea ithutoa.Hoo e ka bang lihora tse 'nè, ntlha ea ho qetela ea pH ke 8.0,' me phello ea ho teba ea cobalt e sebelisoa ka makhasi a magnesium oxide.Sehlahisoa sa cobalt hydroxide se phahame ho feta 36%, sekhahla sa ho hlaphoheloa ha cobalt se feta 99%, 'me sekhahla sa tšebeliso ea magnesium oxide se ka fihla ho 91%.
Ho tsosolosa lisebelisoa tsa cobalt ho tloha tsamaisong ea tharollo ea cobalt sulfate hangata ho amohela ho eketsa magnesium oxide paste ho hlahisa lihlahisoa tsa cobalt hydroxide.Hore na motsoako oa magnesium oxide peista o bolokoa o tsitsitse.Keketseho ea litšila lihlahisoa, e amang boleng ba sehlahisoa, 'me khatello e tlase ea magnesium oxide paste e tla baka ho fokotseha ha cobalt recycling.
