Abstract:
|
Slags produced from metal refinery have been used in Ghana for several purposes including road,
building and other constructions. However detailed compositions of these slags used are not very well known
in Ghana and for that matter the industry players who use them for their constructions. It is for this reason that
this work was conducted to ascertain the composition as well as the levels of the various oxides and metals in
these slags. Neutron activation analysis coupled with gamma ray spectroscopy was used to determine the levels
of these elements in the samples. Levels of the various oxides estimated were P2O5 0.06±0.01- 0.63±0.09, SiO2
20.61±3.09-23.39±3.50, Al2O3 3.81±0.06-4.29±0.06, MgO 3.85±0.53-5.25±0.78, Fe2O3 2.08±0.22-35.00±3.85
mg/kg composition. All the concentrations and compositions obtained are within the range of concentrations found in the Emery composition of slags and also typical of slags produced from an Electric-Arc Furnace (EAF).
