The invention relates to a jigging installation using low frequency combined pulsations of the medium superposed with high frequency pulsations, in order to recover the useful minerals and the gold from the ore and to prepare buckwheat coal, which comprises a body (1) with two lower cone-shaped cells (2 and 2'), separated by a wall (3) and having at the upper side a screen (11) with meshes of different diameter, on which the material layer is set, the pulsations being generated by the simultaneous action on the medium of a metal disk-diaphragm (4) with high frequency vibrations, produced by a universal eccentric (9) operated by an electrical engine (7) through belt transmission (8) by means of a metal rod (6) and of a platband (10) connected with the screen (11) and of some pistons (19) of sheet-metal or wood, integral with some rods (18) connected by some bearings (17) with an axle (15) passing through two devices (16) with universal eccentric or with cams fastened to the edges of the body (1), the axle (15) being rotated by an engine (13) using a rove and belt transmission (14). In another embodiment the jigging installation has both the high frequency oscillation operating part and the low frequency oscillation operating part located at the lower side of the installation. Inventia se refera la o instalatie de zetaj cu pulsatii combinate ale mediului, de joasa frecventa, suprapuse cu pulsatii de inalta frecventa, pentru recuperarea mineralelor utile si a aurului din minereu si preparare de carbuni maruntiti, cu pulsatii combinate ale mediului, de joasa frecventa, suprapuse cu pulsatii de inalta frecventa, care se compune dintr-un corp (1) cu doua celule cu parti conice inferioare (2 si 2'), separate de un perete (3), si avand la partea superioara un gratar (11) cu ochiuri de diametre diferite, pe care se asaza stratul de material, pulsatiile realizandu-se prin actiunea simultana asupra mediului a unei diafragme-disc (4) metalice, cu vibratii de inalta frecventa, produse de un excentric universal (9), actionat de un motor electric (7) prin transmisie cu curele (8) cu ajutorul unei tije metalice (6) si a unei platbande (10) de legatura cu gratarul (11) si a unor pistoane (19) din tabla sau lemn, solidarizate cu niste tije (18) legate cu niste lagare (17) de un ax (15) care trece prin doua dispozitive (16) cu excentric universal sau cu came fixate pe marginile corpului (1), axul (15) fiind rotit de un motor (13) prin transmisie cu saibe si curbele (14). Intr-o alta varianta de realizare, instalatia de zetaj are atat partea de actionare pentru oscilatii de inalta frecventa, cat si partea de actionare pentru oscilatii de joasa frecventa, dispuse la partea inferioara a instalatiei.
