    Feb 21, 2020 Iron ore mining often focuses on looking for hematite deposits known as red iron ore, and magnetite, as they have naturally weak magnetic fields that aid in their purifiion. Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore.Anhui hematite contains 43.21 of iron and 30.11 of silicon it belongs to high silica refractory hematite. In this paper, reverse flotation process was adopted to deal with the ore as a result, good indexes can be obtained, which the iron concentrate grade is 61.76 with 83.06 recovery.
