The thermodynamics of admixture extraction in magmatic melts with the presence of surfactants is considered. A theory for hydrodynamic transfer of the admixtures in a surfactant field is developed. It is demonstrated that admixtures move to zones of increased surfactant concentrations. Equations describing the self-conforming particle motion and surfactant diffusion have been deduced. It is suggested that the extraction process is unstable, which results in a dramatic reduction in the characteristic diffusion times of extraction.
