Phosphorus Removal From Agbaja Iron Ore

Phosphorus removal from Nigeria’s Agbaja iron ore by ...

Phosphorus is an unwanted component of iron ore. Its removal from Nigeria’s Agbaja iron ore by solubilization with Eurotium herbariorum isolated from the ore samples has been achieved using the submerged culture technique. Result obtained shows 61.48% removal of P in 10 weeks through the biomass growth and activities of the filamentous fungus.
