Cobalt imvura ihitamo neza ya MgO

Turabizi ko Mine y'umuringa ya Kongo (Zahabu) ifite ibigega byinshi kwisi.Amabuye yacyo y'umuringa ahanini ni umuringa cobalt oxyde hejuru.Kubijyanye no gushora imari ninshi, umusaruro wo gutunganya umuringa utose wiyongereye.

Igicuruzwa gitose cya Kongo (Zahabu) Umuringa muri rusange ni "amabuye y'agaciro- gukuramo- electrodeposition".Mugihe cyo kwibiza umuringa, dioxyde de sulfure cyangwa sodium sulfate ikoreshwa nkibintu bigabanya kwibiza cobalt.Umuti wa acide sulfurike urimo cobalt y'umuringa utanga umuringa wa cathode nyuma yo gukuramo umuringa.

Kuberako umushinga winganda zaho ufite intege nke cyane, usibye acide sulfurike, mubyukuri ibikoresho byose byinganda bigomba gutumizwa hanze.Kugirango uzigame ibiciro, ibyinshi mubicuruzwa bya cobalt bikorerwa mukarere kaho ahanini bikorwa nibikorwa byavuzwe haruguru.Ikintu gikunze kugaragara cyane cobalt nugukoresha sodium karubone cobalt kugirango ikore karubone ya cobalt.Nyamara, cobalt nkeya muri karubone ikarishye ni mike, inyinshi muri zo zikaba zigera kuri 25%, byongera amafaranga yo gutwara hamwe n’ibindi biciro, kandi cobalt ya sodium karubone irimo umunyu mwinshi wa sodiumi bigoye guhangana na byo.Ibyuka bihumanya ikirere bizatera umwanda ibidukikije, kandi mugihe bizatera umwanda ibidukikije.Niba ikoreshwa muri sisitemu igihe kirekire, bizatera sodium ion nyinshi mu gisubizo, bizagira ingaruka zikomeye ku musaruro wumuringa.Kubera ko politiki y’ibidukikije yo kurengera ibidukikije igenda ikomera buhoro buhoro, ibigo byinshi byatangiye kwiga byinshi mu bijyanye n’ubukungu n’ibidukikije byangiza ibidukikije.Okiside ya magnesiumkurohama tekinoroji ya cobalt nimwe mubyerekezo.

Intego ku ruganda rwo muri Kongo (Zahabu) rwacururizaga amazi, cobalt-irimo umuringa ukuramo amazi muri cobalt, hamwe n’amazi yo gukuramo inyuma, ubushakashatsi bwakozwe ku ngaruka za oxyde ya magnesium na cobalt mu bihe bitandukanye.Mu masaha agera kuri ane, ingingo ya nyuma pH agaciro ni 8.0, kandi ingaruka yo kurohama ya cobalt ikoreshwa hamwe na magnesium oxyde pulp.Igicuruzwa cya hydroxide ya cobalt kiri hejuru ya 36%, igipimo cyo kugarura cobalt kirenga 99%, naho ikoreshwa rya oxyde ya magnesium rishobora kugera kuri 91%.

Kongera gutunganya ibyuma bya cobalt biva muri sisitemu yo gukemura ya cobalt sulfate muri rusange bifata kongeramo paste ya magnesium kugirango bitange umusaruro wa hydroxide ya cobalt.Niba ubunini bwa magnesium oxyde paste bugumaho.Ubwiyongere bwumwanda mubicuruzwa, bigira ingaruka kumiterere yibicuruzwa, hamwe nubushuhe buke bwa magnesium oxyde paste bizatera kugabanuka kwa cobalt.
