Beneficiation of Fe-Mn Minerals in Yunnan Province

Abstract:

The paper recovered the Fe and Mn minerals from a refractory ore in Yunnan province. The grade of Fe in raw ore is 30.16% and the grade of Mn in raw ore is 20.05%. Through technological mineralogy study, we found the Fe was mainly in the forms of Hematite and limonite, and the Mn was mainly in the forms of pyrolusite and psilomelane. Through the process of strong magnetic separation, re-grinding and magnetic separation, the minerals of Fe and Mn were recovered, and the Fe mineral was separated from mixed concentrate successfully. Finally, we got two products. They were Fe concentrate with the grade of 60.35%, recovery of 81.26%, and Mn concentrate with the grade of 37.35%, recovery of 71.26%. This test to increase enterprise efficiency and reduce the environmental pressure is of much benefit.
