Iron ore is the primary raw material for steelmaking, and steel is one of the core materials for modern industry and infrastructure construction. China is the worlds largest steel producer and has a huge demand for iron ore. According to the natural types of ores and ore processing technology performance, ores are classified into three types based on the ratio of TFe/FeO. Among these, magnetite ore (TFe/FeO ≤ 3.5) is characterized by steel gray or gray-black color, granular structure, and massive, banded, spotted, or disseminated texture.
