Kayzero-standardization method of neutron activation analysis study for major and minor elements determined in soils and phosphate rocks of the prospective phosphate mining area in the Hinda district, Republic of Congo

The main objective of the present study was to determine the concentration of major and minor elements contained in soil and phosphate rock samples collected in the prospective phosphate mining area in Hinda district. Samples have been analyzed using k0-neutron activation method through the Moroccan Triga Mark II research reactor. The results showed Al, Fe, K, Mg, Mn and Na as major elements and As, Br, Cr, V and U as minor elements, including rare earth elements in soils and phosphate rocks. These results were compared with other studies reported worldwide. Pollution indicators have been determined to assess pollution status.
