Ferro manganese ni ubwoko bumwe bwibyuma bivangwa cyane cyane bigizwe na manganese nicyuma.Imiti yimiti ya manganese ikora cyane kuruta icyuma.Iyo wongeyeho manganese mubyuma byashongeshejwe, irashobora kubyitwaramo na oxyde ferrous kugirango ibe shitingi ya okiside idashonga mumashanyarazi. ibyuma, icyapa kireremba hejuru yicyuma gishongeshejwe, gabanya umwuka wa ogisijeni mubyuma. Muri icyo gihe, imbaraga zo guhuza manganese na sulferi ziruta imbaraga zihuza ibyuma na sulfure, nyuma yo kongeramo amavuta ya manganese, sulfuru mubyuma bishongeshejwe byoroshye gukora umusemburo muremure wa manganese, sulfure mubyuma byashongeshejwe byoroshye gukora ahantu hahanamye cyane manganese sulfide hamwe na manganese hanyuma ikoherezwa mumatanura, bityo bikagabanya ibirimo bya sulferi mubyuma byashongeshejwe kandi kunoza impimbano no kuzunguruka kwicyuma.Manganese irashobora kandi kongera imbaraga, gukomera, gukomera no kwambara birwanya ibyuma.None rero ferro manganese ikunze gukoresha nka deoxidizer, desulfurizer hamwe na alloy yongeweho mugukora ibyuma kandi bigatuma icyuma gikoreshwa cyane alloy.
