Raw Khoom Npaj
Manganese ore (xws li carbonate lossis manganese oxide) yog crushed thiab av mus rau hauv cov khoom zoo.
Xev
Lub ore yog yaj hauv sulfuric acid (h2so4) kom tau ib qho kev daws teeb meem ntawm manganese sulfate (mnso4).
Tshuaj lom neeg cov tshuaj tiv thaiv: Mnco 3+ h2so4 → mnso {}} h2o.
Ntxuav
Impurities (piv txwv, cov hlau, cov hlau hnyav) raug tshem tawm 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 rau manganese hlau (mn) thiab tso raws li flakes.
Naj hoom: Cov pa thiab cov pa roj av (piv txwv li, O2, yog li ntawd.
Tom qab kho
Cov flakes yog tshem tawm ntawm lub Cathodes, ntxuav kom tshem cov khoom seem electrolytes, thiab qhuav.
Ntim
Cov nplaim hluav taws qhuav yog ntim rau hauv cov dej noo-pov thawj hnab (piv txwv li} ton lub hnab lossis 25 kg woven hnab).
