Abstract

The invention relates to a production method for scandium metal in pure or alloy form using molten salt electrolysis or electrolysis method from scandium salt mixtures prepared by adding CaCI2 and/or MgCI2 salts to ScF3 compound, in order to lower its melting temperature, which is obtained by reacting the initial scandium compound, having the form of (NH4)NaScF6, with HCI in aqueous medium and removing (NH4) and Na with CI from its structure
