Abstract: New-type T-GCT high-performance permanent magnetic drum separator has characteristics of big magnetic angle, long magnetic belt, different magnetic functions, uniform gradually-varied magnetic fields, and strong magnetic fields with water rinse devices for concentrates.An industrial comparative test of T-GCT Separator in Litie concentrator with on-site ordinary permanent magnetic drum magnetic separator is carried out.The results show that the Fe recovery can be improved by 1.48 % and 0.56% respectively with T-GCT separator at stage1 and stage 2 of roughing concentration, yet the concentrate grade can be improved by 0.96 % at stage 3 of cleaning concentration.

Key words: T-GCT high-performance permanent magnetic drum Separator, Ordinary permanent magnetic drum separator, Industrial test
