摘  要: The tailing is a kind of mine solid material that is hard to be re-sorted after the ore separation. Most of the mines in our country build tailings reservoirs on the earth’s surface to reserve the tailings. Due to the limit of the ore separation technique at that time, most of the tailings reserved contain a large number of valuable constituents and the grade is very high. The potential value is remarkable. While, the tailings piled up on the earth’s surface will cause a series of environmental impact including air pollution, land degradation, vegetation deterioration, geological disasters, etc. On the base of the concept of tailings recycling and low-carbon mining industry, this paper discusses the necessity of the tailings recycling management and the methods of tailings recycling. And taking the iron mine as example, it analyzes the economy of resources and the low-carbon effect of the tailings recycling, and concludes that the carbon reduction effect of tailings recycling is significant.
