The feed samples of X, Y, and Z iron ores were ground in the BBM (ball mill refers to a BBM of size 300 mm × 300 mm with smooth liners) to identify the PSD, BWI, and RT of each ore. Grinding experiments were conducted according to Bond's standard test procedure [].For each iron ore sample, the RT taken to produce 250% circulating load in the BBM was measured by a new method.

Hematite is an important ironcontaining mineral [4], and is also the main raw material for ironmaking. Hematite is embedded with extremely fine particle size in hematite ore, and is closely symbiotic with gangues such as quartz, chlorite and amphibole [5]. To achieve the monomer dissociation of useful minerals, fine grinding is required.
