Abstract

Abstract: Aiming at the problem of which a iron mine needed to provide technical supports for subsequent development and utilization,beneficiation test research was carried out.After comparing grinding-low intensity magnetic separation process with grinding-low intensity magnetic separation-magnetic screening process,grinding-low intensity magnetic separation-magnetic screening process was determined which could get better beneficiation indexes.Iron concentrate with yield rate of 77.08%,TFe grade of 67.34%,TFe recovery rate of 94.76% was obtained via raw ore grinding-low intensity magnetic separation-magnetic screening-magnetic screening middlings grinding-low intensity magnetic separation-magnetic screening scavenging process.Magnetic screening process played a pivotal role in the iron ore cleaning upgrading.

Key words: Iron mine, Magnetic separation, Magnetic screening, Cleaning
