Iintlobo zeCobalt Ore kunye neendlela zokuyicubungula
IiCobalt Ores eziphambili: iSulfide kunye neOxide
Ii-ore ze-sulfide, ezifana nezo ziqulethe i-pentlandite kunye ne-chalcopyrite, zinezinga eliphezulu le-cobalt kwaye zihlala zinxulunyaniswa ne-copper kunye ne-nickel. Ezi ore ziyakwazi ukumelana noxinzelelo lomxhuzulane kunye nokwahlukana kwemagnethi ngaphambi koxinzelelo ngaphambi kokunyibilikisa okanye ukuvuza. Ii-ore ze-oxide (i-laterites), kubandakanya i-limonite kunye ne-saprolite, zilawula iindawo zokugcina zangoku kwaye zinezinga eliphantsi le-cobalt kunye nomxholo ophezulu we-iron kunye ne-magnesium. Ii-Laterites zifuna ukuvuza kwe-acid ephezulu (HPAL) okanye ukuvuza kwe-heap ngenxa yesimo sazo sokungaguquki. Ngaphezulu kwe-60% yezinto ezintsha ze-cobalt ngoku zivela kwimithombo ye-laterite. Ukuhluthwa komxhuzulane kunye nokuhlukana kwemagnethi kuphucula ukuhluthwa kweentlobo zombini ze-ore ekuzuzeni kwangaphambili, okuchaphazela ngokuthe ngqo iinkqubo zovavanyo lwe-cobalt ezilandelayo kunye nokuchaneka kohlalutyo lobungakanani. Ukukhethwa kwendlela yokucubungula i-ore ephambili kuxhomekeke kwi-mineralogy, i-cobalt speciation, kunye neendleko, okuqinisa indima yohlalutyo lomxholo we-cobalt kwii-ore ukuze kuphuculwe inkqubo.
Izixhobo zeSibini kunye nokuHlaziya kwakhona
Imithombo yesibini ye-cobalt, kuquka imigodi kunyeibhetriinkunkuma, inegalelo elikhulu kwikhonkco lokubonelela, rhoqo ngaphezulu kwe-15% yemveliso iyonke ye-cobalt yehlabathi. Iinkqubo ze-hydrometallurgical, ezifana nokukhupha i-solvent kunye nokukhuhla ngee-oxidants, zibonelela ngeendlela ezisebenzayo zokubuyisa i-cobalt kwiintsalela ezikumgangatho ophantsi, iibhodi zesekethe, kunye neebhetri ze-lithium-ion ezisetyenzisiweyo. Iinkqubo ze-pyrometallurgical zinyanga iibhetri ezisetyenzisiweyo kunye nenkunkuma ye-metallurgical kodwa zifuna ulawulo oluqinileyo lokusingqongileyo. Ukuphinda kusetyenziswe kwakhona kwanamhlanje kusebenzisa izinzwa zokufumanisa i-cobalt eziphambili ukuze kuvavanywe ngokukhawuleza umxholo, okukhokelela ekuhlukaniseni okuguquguqukayo kunye nokucocwa.
