Hematite and magnetite are the two main minerals in China's numerous iron ore sources. As easily processed mineral resources become depleted, iron ores that are low-grade, fine or mixed, and generally difficult to separate have become our current focus of research and exploitation [1,2].This includes ultrafine disseminated iron ores [], where the target minerals are largely disseminated at a ...
