Abstract

Glucosamine acting a fundamental role in the extraction process of uranium from El-Sebaiya
Phosphate Rock. This process involved selective leaching of uranium (99%) using 1.12 mole of
Glucosamine at 25 °C . The kinetics of the leaching process as well as the reaction mechanism
between Glucosamine and uranium have been discussed in details. From the latter, it was found
that, the reaction was diffusion controlled and the calculated apparent activation energy was 14.
78 kJ/mole.
