FIELD: diamonds recovery. SUBSTANCE: invention relates to isolation of ultradispersed diamonds from aqueous suspension by way of atomization thereof in spouted bed of heated inert charge with the help of pneumatic high-pressure nozzle installed in the basis of bed and subsequent separation of dry product from gaseous heat carrier. According to invention, temperature in the inert charge bed is maintained in the range 100-140 C and flow number N is equal to 1.5-3.0. As inert charge material, fluoroplastic is utilized. EFFECT: improved procedure. 2 cl, 1 dwg
