FIELD: mining and enriching machinery. SUBSTANCE: diaphragm jig has one or several chambers with sieve, diaphragm and drive mechanism of diaphragm positioned on inclined wall of chamber. Diaphragm drive mechanism is essentially hydraulic valve built in diaphragm and coupled with inlet hose and control valve. Diaphragm jig makes it possible to extend range of application in direction of thin particles and to raise degree of extraction of valuable components due to setting of required configuration of water pulsation cycle in chamber depending on sands being jigged. EFFECT: reduced occupied useful area, reduced specific amount of metal and labour intensity for diaphragm jig manufacture. 2 dwge
