GOLD-BEARING SANDS ENRICHMENT LINE Russian patent published in 2017 - IPC B03B9/00 

FIELD: mining.

SUBSTANCE: line for the enrichment of gold-bearing sands includes two modules that are successively connected along the material flow. One of the modules is the enrichment module, consisting of a washing table, screening gateway, coarse and fine fraction hydroclassifier, the output of the coarse fraction hydroclassifier is connected to the input of jigging machine which output is connected to the input of the series-connected concentration tables, and their outputs are connected to the jigging machine in which one of the outputs is connected to coarse fraction centrifugal concentrator, the other one is connected to flotation machine, the input of which is connected to the output of the fine fraction hydroclassifier, the output with fine fraction centrifugal concentrator. Another module for finishing the concentrate consists of vibration screen, device for drying the coarse fraction, magnetic separators, jigging machine, centrifugal concentrator, concentration table, cradle, devices for concentrate drying and units for enrichment in ferromagnetic liquid. The module for finishing the concentrate is additionally equipped in series with low pressure autoclave, centrifugal disintegrator and additional magnetic separator installed between the concentrate drying device and a unit for enrichment in ferromagnetic fluid.

EFFECT: increased line productivity and extraction of gold.
