Abstract

Leaching of lanthanides from phosphogypsum (PG) was carried out using either free acids such as HCl and HNO3 or these acids associated with Nonyl Phenol Ethoxylate (NPE). The factors affecting the leaching process were optimized. Also the kinetics of the leaching investigated as a function of temperature. Based on the experimental results NPE increased the leaching efficiency by 30 % relative to the corresponding free acids. It was found that the leaching process could be described by a shrinking-core model. Also the leaching of lanthanides by the associated system decrease the activation energy from
