FIELD: technological processes.
SUBSTANCE: proposed group of inventions relates to the minerals enrichment, in particular to the precious metals extraction, for example, gold, and can be used in processing both alluvial and technogenic minerals deposits. Precious metals from alluvial and technogenic deposits of minerals extraction method includes disintegration, classification, condensation, main and recleaning screw separations. After the main screw separation, isolating the concentrate, industrial products and tailings. After the main and recleaning screw separations, the concentrate is subjected to magnetic separation. Obtained after the main screw separation industrial product is subjected to recleaning separation. Tailings after classification and tailings after the main and recleaning screw separations are subjected to additional enrichment. Methods are implemented on the production line comprising the sequentially arranged disintegration device, classification device, condenser, main and recleaning screw separators and concentration table. Line is additionally equipped with the magnetic separator installed after the main and recleaning screw separators. Also, the line is additionally equipped with the fine filling sluice to catch large gold.
EFFECT: increase in the of fine and thin gold extraction without loss of large gold, as well as improving the concentrates fine-tuning process.
