LINE FOR PROCESSING GOLD-CONTAINING RAW MATERIALS OF MAN-GENERAL DEPOSITS Russian patent published in 2022 - IPC C22B11/00 B03B9/00 B03B7/00 B03B5/00 

FIELD: hydrometallurgy.

SUBSTANCE: invention relates to the hydrometallurgy of precious metals, in particular the extraction of gold from technogenic deposits. The line consists of the following modules: disintegrating-classifying, free gold extraction, grinding-classifying, thickening, sorption cyanidation, desorption of gold from a saturated sorbent, regeneration of the sorbent, secondary concentration of gold, electrolysis of gold-containing solutions. At the same time, the disintegrating and transporting module is made in the form of a sequentially installed scrubber-butar and a conical screen, and the free gold extraction module is made in the form of a sequentially installed mass flow receiver, a drum distributor of mineral grains by size, locks for the extraction of free gold of large and medium size classes, a receiver of heavy fractions of sluices, a screen, a complex of sequentially interconnected jigging machines and concentration tables, a receiver for small free gold grains, a thin-layer thickener.

EFFECT: line allows to reduce technological losses of gold and increase the reliability of the line for hydrometallurgical processing of gold-bearing raw materials from technogenic deposits due to additional extraction of free gold of large and medium size class in the module.
