Test Research on HIMS-Reverse Flotation of Oolitic Hematite of Longyan Iron Mine

Abstract:

In order to better exploit and utilize the oolitic hematite ore resource in Zhangjiakou region, staged grinding-separation process consisting of high intensity magnetic separation(HIMS) and reverse floatation was adopted in the beneficiation test on the regionally representative oolitic hematite ore of Longyan Iron Mine, Xuan Stee1. The test results indicate that，with Slong pulsating high gradient magnetic separation as HIMS equipment，with NaOH，starch，CaO and TS as flotation reagents，and at a grind of 65％ -200 mesh for the primary grinding and 95％-200 mesh for the secondary grinding，an iron concentrate grading 62.34％ and having an iron recovery of 53.07％ can be achieved after two stage HIMS and one roughing—one cleaning reverse flotation.
