Abstract

The invention relates to a pipe separator (5) for electrostatically separating particles of a mixture of valuable materials, e.g., a mineral salt mixture, having different electrical charges, comprising a carrier pipe (10), wherein the carrier pipe has two field electrodes (8, 9) arranged opposite each other for generating an electric field, wherein the field electrodes (8, 9) are covered toward the inside by an insulating layer.
