Studying on mineralogical characteristics of a refractory

May 09, 2020 The iron-bearing minerals in the oolite are mainly hematite, limonite, chlorite, and collophanite, and a close relationship between the hematite-limonite in the oolites and the iron-containing chamoisite can be observed. Upgrading iron and removing phosphorus from the high-phosphorus oolitic iron ore will be difficult by physical beneficiation.
