A method for the production of metakaolin particles includes following method steps: - preparing a lightweight expandable aggregate material in granulate form; - adding kaolin particles to the lightweight aggregate as a separating agent; - feeding the separating agent-granulate mixture through a kiln; - exposing the separating agent-granulate mixture to thermal energy, in order to expand the lightweight aggregate material, with simultaneous calcination of the kaolin particles into metakaolin particles; and - separating the metakaolin particles from the lightweight aggregate granulate.
