Developments in the physiochemical separation of iron ore
The early beneficiation process, which relied on gravity and magnetic separation, sought to produce an iron concentrate containing a minimum of 64% iron, with about 9% silica. This was the minimum-grade product acceptable to the smelters at that time. ... In China, iron ore beneficiation started with the direct flotation of iron oxides …
