Muaj ob hom kev txo smelting ntawm ferromanganese: flux method (tseem hu ua low manganese slag method) thiab flux-free method (high manganese slag method). Lub hauv paus ntsiab lus ntawm cov txheej txheem flux yog tib yam li cov blast furnace smelting, tshwj tsis yog tias hluav taws xob siv hluav taws xob siv coke rau cua sov. Los ntawm kev ntxiv txiv qaub, lub siab alkalinity slag (CaO / SiO2 yog 1.3 ~ 1.6) yog tsim los txo qhov poob ntawm manganese.
Flux-free smelting tsis ntxiv cov txiv qaub ua rau muaj cov hlau tsis muaj hlau, phosphorus thiab manganese-nplua nuj slag nrog qis alkalinity (CaO/SiO2 tsawg dua 1.0) thiab cov ntsiab lus siab manganese. Txoj kev no muaj tsawg dua slag, uas tuaj yeem txo qis kev siv hluav taws xob, thiab qhov qis slag kub tuaj yeem txo cov evaporation poob ntawm manganese. Nyob rau tib lub sijhawm, cov khoom lag luam manganese-nplua nuj slag (muaj 25 ~ 40% manganese) tuaj yeem siv los ua raw khoom rau smelting manganese-silicon alloys, ua tiav cov txiaj ntsig siab dua. Kev rov qab zoo ntawm manganese (ntau dua 90%).
