FIELD: mining industry; equipment for minerals enrichment. ^ SUBSTANCE: the invention is pertaining to the field of mining industry, to equipment for minerals enrichment, in particular, to the apparatuses for the minerals gravity concentration and may be used for extraction of the useful components from the different grainy materials. The jigging concentrator consists of: the duct; the vibration exciter; the concentration component made in the form of the ribbed wear-proof coating with the transversal ribs and the longitudinal groove with the varying depth conjugated at the lower layer with the inter-rib cavities through the lateral holes; the transversal ribs have inclination in the direction of the longitudinal groove and the tilt in the direction of the jigging concentrator loading. At that there is a possibility to change their number, height and tilt. At the outlet end of the longitudinal groove there is the fixed concentrate collector. The duct and the concentration component have the possibility to change the frequency and the amplitude of vibration. The concentration component is made in the form of the plate, the transversal ribs on which are made together with the plate. At that the plate is simultaneously used as the bottom of the longitudinal groove. The longitudinal groove has the side walls with the lateral holes made in these walls. The plate has the longitudinal walls vertically arranged and densely connected with the outer butts surfaces of the transversal ribs. The technical result of the invention is the increased efficiency of the minerals grading and gravity concentration. ^ EFFECT: the invention ensures the increased efficiency of the minerals grading and gravity concentration. ^ 2 dwg
