Siyazi ukuthi iCongo (Gold) Copper Mine inezinqolobane eziningi emhlabeni.Insimbi yayo yethusi ngokuyinhloko i-cobalt yethusi eyenziwe nge-oxidized ngaphezulu.Mayelana nokutshalwa kwezimali okuthe xaxa, ukukhiqizwa kokucwenga ithusi elimanzi kuye kwanda nakakhulu.
Inqubo yokukhiqiza emanzi yeCongo (Gold) Copper ngokuvamile "i-ore leaching- extraction- electrodeposition".Ngesikhathi senqubo yokucwiliswa kwethusi, i-sulphur dioxide noma i-sodium sulfate isetshenziswa njenge-ejenti yokunciphisa ukucwilisa i-cobalt.Isixazululo se-sulfuric acid esine-cobalt yethusi sikhiqiza ithusi le-cathode ngemva kokukhishwa kwethusi.
Ngenxa yokuthi isisekelo sezimboni zendawo sibuthakathaka kakhulu, ngaphandle kwe-sulfuric acid ethile, ngokuyisisekelo zonke izinto ezisizayo zezimboni zidinga ukungeniswa kwamanye amazwe.Ukuze ulondoloze izindleko, iningi lemikhiqizo ye-cobalt ekhiqizwa endaweni yasendaweni iningi lenziwa inqubo engenhla.Izinhlanganisela ezivame kakhulu ze-cobalt zisebenzisa i-sodium carbonate cobalt ukukhiqiza i-cobalt carbonate.Kodwa-ke, i-cobalt ephansi ku-cobalt carbonate enzima iphansi, iningi layo elingama-25%, okwandisa izindleko zokuhamba nezinye izindleko, futhi i-sodium carbonate cobalt iqukethe inani elikhulu likasawoti we-sodium okunzima ukubhekana nayo.Ukukhishwa kwegesi okuqondile kuzodala ukungcoliswa kwemvelo, futhi ngenkathi kuzodala ukungcoliswa kwemvelo.Uma isetshenziswa ohlelweni isikhathi eside, izobangela inani elikhulu le-sodium ions esixazululweni, esizothinta kakhulu ukukhiqizwa kwethusi.Njengoba izinqubomgomo zendawo zokuvikela imvelo ziqinile kancane kancane, izinkampani eziningi seziqalile ukufunda izinqubo zokukhiqiza i-cobalt ezongayo nemvelo.I-Magnesium oxideubuchwepheshe be-cobalt obuzinzile bungenye yezinkomba.
Iqondiswe ezimbonini zendawo ezincibilikisa amanzi ezimanzi zaseCongo (Gold), i-cobalt-equkethe uketshezi olukhipha ithusi ku-cobalt, noketshezi olukhipha ngemuva, umphumela we-magnesium oxide ne-cobalt ngaphansi kwezimo ezihlukene kwacwaningwa.Cishe emahoreni amane, inani lephoyinti lokugcina le-pH lingu-8.0, futhi umphumela wokucwilisa i-cobalt usetshenziswa ne-magnesium oxide pulp.Umkhiqizo we-cobalt hydroxide ungaphezu kuka-36%, izinga lokubuyisela i-cobalt likhulu kuno-99%, futhi izinga lokusebenzisa i-magnesium oxide lingafinyelela ku-91%.
Ukugaywa kabusha kwezinsimbi ze-cobalt kusuka ohlelweni lwesisombululo se-cobalt sulfate ngokuvamile kwamukela ukungeza unamathisele we-magnesium oxide ukukhiqiza imikhiqizo ye-cobalt hydroxide.Ukuthi ukugxila kwe-magnesium oxide paste kugcinwa kuzinzile.Ukwanda kokungcola emikhiqizweni, okuthinta ikhwalithi yomkhiqizo, kanye nokugxila okuphansi kwe-magnesium oxide paste kuzobangela ukwehla kokuvuselelwa kabusha kwe-cobalt.
