Test Research on Reducing Grade of Tailing of Dahongshan Iron Concentrator

Abstract

Abstract: The tailing of Dahongshan Iron Concentrator has a high iron grade of 27.92%, representing a serious metal loss. Further reduction of the tailing iron grade for comprehensive recovery of resource is imperative. Four schemes were tested and the one of high gradient magnetic separation (HGMS) flowsheet (HGMS roughing, HGMS cleaning and HGMS scavenging) achieved good metallurgical performances, the tailing iron grade being decreased to 11.96% and the concentrate having a grade of 52.38% and recovery of 73.97%.

Key words: Iron tailing, Grade, Recycling of resource
