Dry Magnetic Separation Recovery Iron from Steel Slag Powder

摘要

There are a lot of iron particles in the steel slag powder that can be recycled. In this work, the technological parameters of dry magnetic separation were optimized and the screening processwas used to replace the traditional magnetic separation process by low-intensity magnetic field. Somore than 80 wt.% concentrate of the iron was obtained, which improved the efficient recovery and rational utilization of steel slag powder.
