FLOW LINE FOR ENRICHMENT OF POLYMETALLIC RAW MATERIAL AND ISOLATION OF FINISHED PRODUCT Russian patent published in 2017 - IPC B03B9/00 

FIELD: machine engineering.

SUBSTANCE: line includes a washing-and-grinding module, a module of basic gravitational concentration of mineral raw material installed in the direction of transport mass flow, and a module of basic gravitational concentration of mineral raw material. The line is additionally equipped with a module for final grinding of gravitation tails containing a ball mill and classifying apparatuses, and module for isolation of finished product, electrolyzers for intensive cyanidation of gravitational concentrates, electrolyzers for isolation of cathode gold, dosing pumps, collecting and storage tanks. The washing and grinding module comprises wet self-disintegration mills and ball mills closed with each other through a classifier. The module of basic gravitational concentration of mineral raw material has jigging machines arranged in series, concentration tables and centrifugal concentrators.

EFFECT: increased extraction efficiency of free gold and lead grains from polymetallic ores, reduced loss of valuable component in small classes.
