Open publisher page 2 citations

Abstract

A fine fraction ilmenite ore contains 4.16% TiO2 and 18.15% TFe,and ilmenite is the main valuable mineal,as well as with a small quantity of rutile and perovskite.Based on the characteristics of finely disseminated size,low grade and complex properties of process mineralogy,a sequence of tests were carried out,such as grinding fineness test,magnetic intensity test and shaking table test.The optimal experimental conditions were confirmed.By the combination flowsheet of low-intensity magnetic separationhigh-intensity magnetic separation-shaking table gravity based on size distribution,ilmenite rough concentrate grading 41.26% TiO2 was obtained with recovery of 45.82%,and it could provide the service for further treatment.
