hitamo ibikoresho bibisi nkamabuye ya manganese, kokiya, hekeste nibindi bikoresho fatizo hanyuma ubanze ubivure; kwishyuza itanura hamwe no kuvanga no kuvanga; gushonga ibikoresho bibisi mubushyuhe bwinshi mumatara ya arc cyangwa itanura riturika, hanyuma uhindure okiside ya manganese mubyuma bya manganese mubidukikije bigabanya gukora amavuta; hindura ibihimbano hamwe na desulfurize; gutandukanya icyuma cya slag hanyuma utere ibishishwa bishongeshejwe; na nyuma yo gukonjesha, ibinyomoro bikorerwa ikizamini cyiza kugirango cyuzuze ibipimo. Iyi gahunda ishimangira gukoresha ingufu no kurengera ibidukikije, ikubiyemo ikoranabuhanga rigezweho ryo kugabanya umwanda no kunoza imikorere.
Uburyo bwo gushonga ferromanganese nigikorwa cyo kubyaza umusaruro ingufu nyinshi kandi bigira ingaruka kubidukikije. Kubwibyo rero, igishushanyo mbonera n’imikorere y’itanura rya ferromanganese igezweho bigenda byibanda cyane ku kuzigama ingufu no kugabanya ibyuka bihumanya ikirere, ikoranabuhanga ryangiza ibidukikije no gutunganya ibicuruzwa, nko gukoresha ikoranabuhanga rigezweho ryo gutwika, sisitemu yo kugarura imyanda, hamwe no gukusanya ivumbi n’ibikoresho byo gutunganya, kugira ngo bikurikirane kugabanya ingaruka ku bidukikije no kuzamura umusaruro.
