Kev npaj ntawm cov ntaub ntawv raw
Manganese ore (xws li manganope carbonate lossis manganese oxide) yog crushed thiab av mus rau hauv cov khoom zoo.
Xev
Lub ore yog yaj hauv sulphuric acid (h2so4) los tsim kev daws teeb meem ntawm manganese sulfate (mnso4).
Tshuaj lom neeg cov tshuaj tiv thaiv: Mnco 3+ h2so4 → mnso {}} h2o.
Ntxuav
Impurities (piv txwv li hlau, cov hlau hnyav) raug tshem tawm los ntawm pH kev hloov kho, oxidation lossis precipitating cov neeg sawv cev (piv txwv li ammonia, hydrogen peroxide).
Elololsissis
Cov tshuaj MMSO4 yog pub rau hauv cov hluav taws xob electrolytic.
Ncaj qha tam sim no (DC) muab:
Tus kws uanhahode: Manganese ions (mn {2+) yog txo kom txo mus los hlau manganese (mn) thiab precipitated raws li flakes.
Naj hoom: Cov pa thiab cov pa roj av (piv txwv li O2, so2) raug tso tawm.
Tom qab ua
Cov flakes yog tshem tawm ntawm lub Cathodes, ntxuav kom tshem cov khoom seem electrolytes, thiab qhuav.
Lub thawv
Cov nplaim hluav taws qhuav yog ntim rau hauv cov dej noo-pov thawj (piv txwv li, 1-tuj tej hnab lossis 25-kg woven hnab).
