Abstract

Slon–2000 vertical ring and pulsating high–gradient magnetic separator is an efficient industrial equipment for processing weakly magnetic minerals. It has been recently developed at the Ganzhou Non–Ferrous Metallurgy Research Institute. A six–month commercial testwork to process low–grade hematite ore was completed in Chong Changeling Mineral Processing Plant in 1995. compared with WHIMS–2000 wet high–intensity magnetic separator, the grade of the concentrate is by 7.21% higher the grade of the tailings lower by 5.41% and the iron recovery higher by 7.36%. Particularly, the matrix is always clean so that the matrix clogging usual in the WHIMS – 2000 machine has been overcome.
