Description

This research focused on studying the effect of sulfuric acid concentrations on the leaching of different radionuclides (238U and 235U series) in two samples (high- and low-grade). The activity concentrations of radionuclides in the uranium series (238U and 235U) were measured by an HPGe detector. The leaching efficiency of 238U and 235U series was different in the samples and the leaching percent of 230Th was the highest in the samples, which may be due to the presence of the organic matter. There are radioactive disequilibria between 238U, 234U and 230Th in leachate and residual phase due to redistribution between acid-soluble and acid-resistant phases. (author)
