Abstract

The present invention relates to an azolethione flotation collector and application thereof. According to the application, an azolethione compound such as a 1,3,4-thiadiazole-2-thione compound, a 1,3,4-oxadiazole-2-thione compound, a 1,2,4-triazole-3-thione compound or a 1,2,4,5-tetrazole-3-thione compound is used as a mineral flotation collector to be applied to ores containing copper, zinc, lead, nickel, cobalt, platinum, palladium, silver or gold minerals to realize flotation recovery of valuable metal minerals. Compared with common flotation collectors in the existing technologies, the flotation collector of the present invention can effectively improve enrichment and recovery of copper, zinc, lead, nickel, cobalt, platinum, palladium, silver or gold minerals.
