FLUSHING-SORTING COMPLEX OF INCREASED EXTRACTION OF REBELLIOUS GOLD Russian patent published in 2020 - IPC C22B11/12 B03B7/00 B03B5/72 

FIELD: obtaining noble metals.

SUBSTANCE: invention relates to flushing-sorting complexes for extraction of gold from gold-containing sands. Gateway part consists of inertial heavy screen, output of which is connected to cavitator input, cavitator output is connected to input of pulp flow divider, outputs of pulp flow divider have taps to bins-dividers, which are connected with jigging machines by means of chutes providing for self-flow of pulp flows, wherein streams from jigging machines are fed into distribution bin, in which there is a hydraulically actuating device for capturing light suspensions and discharging them to inlet of bin-dehydrator, said system is connected by gravity flow system with successive unloading concentrators one after the other to ensure production of gold-containing concentrate at the outlet of the latter. Gateway part is connected through distribution hopper to additional screen for treatment of heavy fractions, slurry outlet gate of which is made with branches and connected to inputs of additional cavitators having branches, and cavitators branches outputs through stitches are connected to jigging machines inlets, all outlets of which are connected to series-connected jigging machines, providing removal of residue into tails and direction of pulp flows to one and second jigging machines to produce gold-containing concentrate at their outlet.

EFFECT: extraction of rebellious gold.
