Abstract: Based on the research on the ore properties of a molydbenum tailings from henan, carried out the dressing tests to recover molybdenum, sulfur and tungsten minerals. The results show that molybdenum concentrate with 48.35% grade and 61.24% recovery, sulfur concentrate with 38.72% grade 84.81% recovery, tungsten concentrate with 48.70% grade 78.16% recovery can get through the closed circuit process of slelective flotation to molybdenum, sulfur and tungsten when grinding the ore sample to -200 mesh accounting for 70%.

Key words: Tailings after choosing molybdenum, Selective flotation, Comprehensive recovery
