1. Method for extracting rare-earth and radioactive materials from dumps of phosphogypsum, consists in, material in flow is separated with the help of actuating mechanism electronic method with degree of transparency material to electromagnetic radiation and ability to of luminescence, characterized in that flow of material much multiple is scanned by laser beam in the form of strip or raster. 2. Method of according to Claim 1, characterized in that scanning of material is laser radiation simultaneously with two laser beams in two ranges in infrared-range, at frequencies of transparent for of phosphogypsum and opaque for particles of rare-earth materials and uf-range by capability of particles of rare-earth materials to luminescence of, and flow of material is formed by compression of in belt of the same thickness, from which impact technique knock opaque to infrared-radiation and luminescent under action of ultraviolet radiation particles of rare-earth materials with the help of actuating mechanism, and for separation of radioactive materials from flow phosphogypsum is used of the induced radiation luminescent radiation, electronic signal from which is fed to actuating mechanism. 3. Electronic separator, including body, bin with feeder, sources of electromagnetic radiation, receivers of electromagnetic radiation, electronic signal processing unit and control, actuating mechanisms, receivers fractions and power supply source, characterized in that separator has laser sources electromagnetic radiation : IR-laser and uv-laser, scanner for scanning laser beam, and receivers of electromagnetic radiation are made in the form of 2 |
