Abstract

Leaching-out of scandium(III) from a fluoride concentrate with a solution of ammonium hydrofluoride is analyzed. Results of a kinetic experiment on leaching-out of scandium(III) at various temperatures and reagent concentrations are presented. The basic characteristics of the process are calculated: activation energy, reaction order with respect to the reagent, and rate constant. Specific features of the process of leaching-out of scandium(III) from a fluoride concentrate are demonstrated.
