A Combined Beneficiation Process to Recover Iron Minerals from a Finely Disseminated Low-Grade Iron Ore

Abstract:

In this research, a refractory iron ore is processed, according to the basic facts of mineralogical study. Mineralogy shows that the ore is characterized by the finely disseminated iron minerals with a small amount in the ore. Iron minerals in the ore are mainly hematite and magnetite. On the basis of the ore characteristic, a flowsheet of "stage grinding-low intensity magnetic separation-high intensity magnetic separation-gravity concentration by fine shaking table" was developed. An iron concentrate assaying 51.45% Fe at a recovery of 62.12% was obtained when the raw ore contains 18.61% Fe.
