FIELD: mining; technological processes.
SUBSTANCE: invention relates to the enrichment of minerals and can be used for wet gravity extraction of nuggets of gold and other precious metals of alluvial deposits, as well as the classification of materials by size. Jigging machine comprises a flat sieve, a drive connected to the sieve, which provides a vertical movement of the sieve. Around the sieve a shell is fixed in the form of a vertical cylinder, around which are fixed blades, located at an inclination to the sieve plane. Sieve is located inside the container with water. Drive is made in the form of a flexible suspension connected to the shell.
EFFECT: increase in the horizontal component to increase the rate of segregation.
