ELECTROSTATIC SEPARATION OF MIXTURE OF VALUABLE MATERIALS, FOR EXAMPLE, MINERAL SALT MIXTURE, BY MEANS OF PIPE SEPARATOR, AND DEVICE FOR ELECTROSTATICALLY SEPARATING SUCH MIXTURE OF VALUABLE MATERIALS BY MEANS OF PIPE SEPARATOR, AND METHOD FOR ELECTROSTATIC SEPARATION Russian patent published in 2016 - IPC B03C7/12 B03C3/30 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to electrostatic separation of mixture of valuable substances. Tubular separator comprises housing pipe, having located on one end an inlet for inlet of mixture of gas and solid substance, two opposed field electrodes for deflection of positively and negatively charged particles of solid substance in stream of mixture, two installed on other end of pipe separation tongues to separate positively and negatively charged particles of substance from each other and for further passage and outlet in middle of bearing pipe a stream of gas and neutral or insufficiently charged particles. Field electrodes on its side facing inner space of pipe are closed by an insulating layer.

EFFECT: preventing suspended particles from sticking to electrodes, higher efficiency of electrostatic separation.
