This work investigated the bulk geochemistry of fifteen (15) samples of Delta Steel Company (DSC) dump slag produced by the direct reduction steelmaking process, using the X–ray fluorescence spectroscopy (XRF) method and glass discs prepared from each of the fifteen test slag samples. The results indicate the presence of major amounts of CaO(36.62%), MgO(9.77%), Fe2O3(27.32%), SiO2(19.86%), Al2O3(5.43%), low amounts of MnO(1.46%), TiO2(0.42%), Cr2O3(0.17%), P2O5 (0.53), and minor amounts of SO3(0.04). The geochemical composition of the slag indicates suitable use as iron making blastfurnace feed and as fertilizer. The low amount of MnO in the slag is advantageous as it can reduce the disadvantage of probably causing refractory lining destruction in the presence of a notable amount of K20. The use of this slag would contribute to the conservation of natural steelmaking resources, improved crop yeild and reduction in CO2 emission in the company environment.Â
