The utility model relates to devices for screening and enrichment of gold-bearing placers as part of a two-stream enrichment plant. The technical task of the utility model is to ensure the efficiency of the extraction of fine gold during the enrichment of sands of all categories of washability during long-term operation of the device while maintaining the transporting ability of the pulp throughout the entire service life of the device. The task is solved by a grate sluice screen, which is a sluice, at the bottom of which prospectors or miners' moss is laid, having stencils made of a round material with a diameter of 20 mm, connected by a round material of a smaller diameter, while vertical stops are welded to the stencils, connected by plates that differ by the fact that the plates are located across the round material and touch the moss surface with one edge, forming thresholds for the settling of heavy gold particles.
