Abstract: The pyrite minerals of Anhui Dabaozhuang Plant were recovered by flotation with CuSO4 as activator，7022 and 9010 as collectors and terpenic oil as frother，of which the process had the disadvantages of environmental pollution and poor production indexes.In order to solve the problems，sulfur flotation tests were conducted with new environmental protection reagent AT908 as collector and BK201 as frother.The sulfur grade and recovery of the sulfur concentrate could be improved by 1.60 and 2.64 percentage points，respectively，on the conditions of without changing flotation flow sheet and reducing reagents types and dosages.The new reagents had the advantages in environmental protection，economic benefit，and production management.
