Currently, high-grade iron ore reserves are being depleted and the utilization of low-grade and refractory iron ore is a suitable way to solve this problem . In China, a large reserve of refractory iron ore lacks appropriate treatments due to its properties such as poor iron grade, complex composition and fine-grained granularity.
