Hauv kev siv hlau ua, nws yog siv los ua deoxidizer thiab alloy ntxiv, thiab nws yog kev siv hlau ntau tshaj. Cov hmoov av manganese siv rau smelting ferromanganese feem ntau muaj 30-40% manganese, cov ferromanganese piv tau ntau dua 7, thiab cov phosphorus-manganese piv tsawg dua 0.003. Ua ntej smelting, yuav tsum tau muab cov roj carbonate carbonate ua ntej, thiab cov ntaub ntawv zoo yuav tsum ua kom tawg mus rau hauv agglomerates. Ores nrog cov hlau siab thiab phosphorus cov ntsiab lus feem ntau tsuas yog siv tau ua ke, lossis tsawg-hlau thiab tsawg phosphorus manganese-nplua nuj slag tuaj yeem tau txais los ntawm kev xaiv txo. Coke yog siv los ua tus neeg txo qis thaum tua, thiab qee cov nroj tsuag tseem tau nruab nrog cov nplaim hluav taws lossis cov pleev anthracite. Lub koom haum pabcuam cov khoom siv yog cov feem ntau cov kua qaub, thiab silica feem ntau ntxiv thaum smelting manganese-silicon alloy.
Tus txheej txheem thoob ntiaj teb ntawm carbon ferromanganese yog 75-80% manganese. Txhawm rau hloov kom haum rau cov khoom siv raw nrog cov qib qis ntawm manganese ore, Tuam Tshoj stipulates ib hom npe nrog qis dua cov ntsiab lus manganese (hluav taws xob ua kom sov ferromanganese muaj ntau dua 65% manganese, tawg ua kom sov ua haujlwm ferromanganese muaj manganese 50% saum toj no). Sij hawm dhau los, smelting carbon ferromanganese feem ntau yog siv cov tshuab ua kom tawg. Nrog rau kev txhim kho ntawm lub zog fais fab, hluav taws xob hluav taws xob tau maj mam nce lawm. Western Tebchaws Europe thiab Tuam Tshoj feem ntau yog siv cov qhov cub tawg, Norway thiab Nyijpooj txhua tus siv hluav taws xob, thiab cov hlau ua haujlwm tshiab hauv Soviet Union, Australia, Brazil thiab lwm lub tebchaws kuj siv hluav taws xob.
