Abstract

A mathematical analysis of the obtained experimental data was performed using topochemical equations in a linearized form: Kazeev–Erofeev–Kolmogorov, Ginstling–Brounshtein, Jander, and Gray–Weddington equations. It was found that the interaction mechanism of nepheline concentrate with sulfuric acid is most accurately described by the Ginstling–Brounshtein equation. The activation energy of the process was determined, based on which it was concluded that the process is controlled by kinetics.
