Dab tsi yog ferromanganese cov tshuaj tiv thaiv?
Ferromanganese yog tsim los ntawmcarbothermic txoNyob rau hauv ib lub moj tej tawg sov los yog hluav taws xob arc rauv. Qhov tseem ceeb ntawm cov tshuaj lom neeg koom nrog kev txo cov manganese oxides (los ntawm ore) siv carbon (Coke).
Cov kev cuam tshuam ntau ntxiv:
Stepwise Txo ntawm manganese oxides:
MNO2 → Rhaub Rhaub 2T3 → RHMMNK3O4 → ROHMNNOMNO2 Tshav Kub Kub Mn2 O3 Tshav Kub Kub Mn3 O4 Tshav Kub Kub
(Cov no yog thermal decomposition kauj ruam ua ntej txo qhov kawg.)
Kev txo cov pa roj carbon (Coke):
MNO + CN MN + CO (Thawj cov tshuaj tiv thaiv) MNO - C ...} {}}}} {} {}} co (hlau oxide txo)
Silicon (Si) & phosphorus (p)

Refining (rau cov qib qis carbon):
Txheej Txheem Silicothermic:Siv Ferrosilicon kom txo MNO yam tsis muaj ntxiv carbon:
2mno + si → → 2mn + sio22mno + Si → 2mn + Sio2
