Zusammenfassung:	The utility model relates to a system for efficiently recovering gold from dump leaching tailings. An ore grinding and grading system is connected with a roughing system through a first stirring barrel and a second stirring barrel; a tailing outlet of the roughing system is sequentially connected with feed ports of the scavenging system I and the scavenging system II, and tailings are discharged from a discharge port of the scavenging system II; a concentrate outlet of the roughing system is connected with a feed inlet of the first flotation column, a concentrate outlet of the first flotation column is connected with a feed inlet of the second flotation column, a tailing outlet of the second flotation column is connected with the feed inlet of the first flotation column, and gold concentrate is arranged at the concentrate outlet of the second flotation column. A tailing outlet of the first flotation column is connected with a feeding hole of a first-stage flotation tank of the roughing system; a concentrate o
