Kev lag luam ua
Manganese tuaj yeem ua tiav kev tsim khoom lag luam, thiab yuav luag tag nrho cov manganese yog siv hauv kev lag luam steel los tsim cov manganese hlau alloys. Hauv qhov cub tawg, manganese hlau alloy tuaj yeem tau los ntawm kev txo qhov tsim nyog ntawm cov hlau oxide (Fe ₂ O3) thiab manganese dioxide (MnO ₂) nrog carbon (graphite). Cov hlau ntshiab manganese tuaj yeem tsim los ntawm electrolyzing manganese sulfate (MnSO ₄).
Hauv kev lag luam, manganese hlau tuaj yeem ua tauualos ntawm electrolyzing manganese sulfate tov nrog ncaj qha tam sim no. Txoj kev no muaj tus nqi siab, tab sis qhov purity ntawm cov khoom tiav yog qhov zoo.
Cov tshuaj npaj siv manganese ore hmoov thiab inorganic acid los teb thiab cua sov los tsim manganese ntsev tov. Nyob rau tib lub sijhawm, ammonium ntsev yog ntxiv rau kev daws raws li tus neeg sawv cev buffering. Hlau raug tshem tawm los ntawm kev ntxiv cov oxidizing tus neeg sawv cev rau oxidation thiab neutralization, hnyav hlau raug tshem tawm los ntawm kev ntxiv ib tug sulfurizing purification tus neeg saib xyuas, thiab ces lim thiab sib cais. Electrolytic additives yog ntxiv rau cov tshuaj raws li cov tshuaj electrolytic. Txoj kev sulfuric acid leaching yog dav siv nyob rau hauv industrial ntau lawm los tsim electrolytes, thiab txoj kev ntawm electrolyzing manganese hlau nrog manganese chloride ntsev tov tseem tsis tau tsim ib tug loj-scale ntau lawm.
Laboratoryua
Laboratoryuatuaj yeem siv cov txheej txheem pyrometallurgical los tsim cov hlau manganese, thaum cov txheej txheem pyrometallurgical suav nrog kev txo cov silicon (hluav taws xob silicon thermal method) thiab txo cov txhuas (txhuas thermal method).
