Abstract

Abstract The article provides the problem of extracting rare earth metals from technogenic raw materials. The analysis showed that there is no effective technology. It is required to consider the thermodynamic and kinetic parameters of the carbonization process. The process of carbonization of sediments of light lanthanides is considered. The work determines the effect of temperature and degree of mixing on the extraction process. The activation energy of the process was calculated. The equation for the dependence of the reaction rate on temperature is given It was shown that the process of carbonization of light lanthanides proceeds in the diffusion region.
