Zusammenfassung:	The invention provides a dressing technology for recycling ultra-low-level gold ore. The dressing technology for recycling the ultra-low-level gold ore is composed of an ore washing and screening system, a slime processing system, a carbon leaching system and a dump leaching system, wherein the technological raw ore is directly screened and washed, the ore sand is subjected to dump leaching, the slime is subjected to the stage classification, stage reelecting recycling particle minding and the carbon leaching, gold concentrate, dump leaching gold loaded carbon and carbon leaching gold loaded carbon of a first segment reelecting returning path and a second segment reelecting returning path are obtained, and the reelecting gold concentrate and the gold loaded carbon are sent to a gold melting plant for treatment to obtain gold ingot. According to the dressing technology, the oxidized gold ore with the gold content of the raw ore being under 0.4g/t and the mud content being above 25% is adopted, the gold dressing recycling rate reaches above 75%, the ultra-low-level gold ore resource is fully used, the gold ore resource is enlarged, the water returning use is strengthened in all steps, the corresponding work is returned according to the water returning quality, water is saved, and the ore per unit consumes under 0.23m3/t of water.
