Beneficiation Experiment on a High-silica Low-grade Hematite Ore in Xinjiang

Abstract

Abstract: Ore dressing processes consisting of stage grinding-stage high gradient high intensity magnetic separation-reverse flotation were applied for development and utilization of a high-silica low-grade hematte ore in Xinjiang. The results showed that ironc concentrate with Fe grade of 61.10% and Fe recovery of 65.63% was achieved throght the process flowsheet of grinding-high intensity magnetic separation-regrinding of coarse concentrate-clean concentration by high intensity magantic separation-one roughing and one cleaning reverse floatation of the high intensity concentrate-middles back to the flowsheet.

Key words: Hematite, High intensity magnetic separation, Reverse flotation
