SUBSTANCE: invention relates to the mining and is intended for the gold-containing sands enrichment with the placer deposits open development. Gold-containing ores enrichment plant includes hydromechanical screen with the water supply system to incoming gold-containing ore and sluice box. Plant further comprises the concentrated productive formation forming device, which is mounted under the screen sieve and consists of two adjacent hoppers without bottoms. On the hoppers side walls vibrators are fixed. Above the hoppers controlled by hydraulic cylinders mobile damper is arranged. Under each hopper, by one compartment without bottom is installed, containing vertical sides, tightly resting against the horizontal decking, which is the hoppers and compartments common bottom. Compartments are configured to alternately extended along the guides towards the sluice box receiving hopper and to unload the concentrate into it.
