INTENSIFICATION of chemical and physical processes <br>REMOVAL OF HEXAVALENT CHROME AND OTHER HEAVY METALS in AVS<br>REMOVAL OF CYANIDES in AVS:<br>GRAPHENE, NANOPOWDERS, MICROPOWDERS etc.<br>A method for graphene obtaining from <br>graphite includes preliminary grinding of <br>natural graphite to a fraction of up to 1 <br>mm, placing the crushed graphite in a <br>vortex layer device (AVS) and its <br>activation for 6-20 minutes.<br>On AVS-P150, we obtain nanoscale <br>graphene by mechanical separation of <br>particles of natural graphite densely <br>crystalline (vein), crystalline (scaly), <br>cryptocrystalline (amorphous, <br>microcrys
