In the current domestic common iron-selecting process flow, two to three permanent-magnet drum magnetic separators are generally adopted for coarse selection and fine selection, and a method for controlling the product precision by a magnetic separation column is adopted finally, so that tailing slurry contains particles discarded after coarse selection and fine selection of each section, and has the three remarkable characteristics of large volume, low concentration and wide particle size distribution. In addition, most mineral resources in China belong to polymetallic ores, many non-ferrous metal ores contain considerable iron resources, but the iron resources in tailing pulp are not effectively recycled in the conventional flotation and sorting process flow, and the flotation tailings have low iron content but considerable total amount.
