Among the iron ore resources in China, the easily beneficiated iron ore resources are declining. Iron ore resources are characterized by more lean ore, less rich ore, and more associated minerals. The composition of the ore is relatively complex, and the grain size of the ore is mostly finer, which causes certain difficulties in beneficiation. .
