| Abstract: | Procedures for the determination of gold and silver in copper concentrates, using k0 based neutron activation analysis, were developed and tested. The effects of gamma-ray self attenuation, neutron self-shielding and spectral interference were considered; precision, accuracy, and detection limits were studied by repeated analysis of copper concentrate internal reference materials. The analytical results have shown good precision and satisfactory accuracy in concordance with the detection limit and range of concentration. |
