Abstract

Disclosed are a method for recycling an iron ore tailing and use thereof. The method includes: 1) conditioning the iron ore tailing to obtain a first slurry, adding water glass and a sodium oleate-associated substance sequentially to the first slurry to obtain a first mixture, and subjecting the first mixture to first flotation to obtain a mixed flotation foam product and a mixed flotation grit; 2) filtering the mixed flotation foam product to obtain a solid, drying, roasting at 400° C. to 650° C., and grinding to obtain a ground product; and 3) conditioning the ground product to obtain a second slurry, adding sodium sulfide, water glass, sodium alginate, hydroxamic acid, and terpenic oil sequentially to the second slurry to obtain a second mixture, and subjecting the second mixture to second flotation to obtain a rare earth concentrate and a rare earth tailing.
