Niobium Production

Bayan rabuwa da sauran ma'adanai, ana samun gauraye oxides na tantalum Ta2O5 da niobium Nb2O5. 
Ana ƙara ƙananan ƙwayoyin oxidizers kamar sodium nitrate don haɓaka halayen. Sakamakon shi ne aluminum oxide da ferroniobium, wani gami na baƙin ƙarfe da niobium da ake amfani da su wajen samar da ƙarfe.Ferroniobium ya ƙunshi tsakanin 60 da 70% niobium. Ba tare da baƙin ƙarfe oxide ba, ana amfani da tsarin aluminothermic don samar da niobium. Ƙarin tsarkakewa ya zama dole don isa ga ma'auni don abubuwan haɗin gwiwa.
