Abstract: | Two distinct analytical methods have been described for analysis of W in tungsten ores. For the proposed study, thick and thin samples were analyzed by using X-ray fluorescence technique with great accuracy. Standard comparison method is based on the measurement of K line for tungsten. Also, W has been determined in similar ore samples by neutron activation analysis followed by X-ray spectrometry employing a238Pu-Be neutron source. The measured Re K-X rays are emitted in internal conversion of137W produced during thermal neutron activation. |
