Ore Blend Grinding at HPGR and Ball Mill. The ore blend was ground in a pilot-scale HPGR (1 m diameter × 0.32 m width) at a maximum feed rate of 50 t/h. The ground product was recirculated to the HPGR feeding hopper five or seven times, wherein every recirculation steps a sample was gathered for moisture and size distribution measurement.

grinding. The ore must be ground to a particle size sufficiently close to the grain size of the iron-bearing mineral to allow for a high degree of mineral liberation. Most of the taconite used today requires very fine grinding. Prior to grinding, the ore is dry-crushed in up to six stages, depending on the hardness of the ore.

The choice of grinding circuit is based on the density and hardness of the ore to be ground. Although use of the rod or ball mill grinding is quite common, a few facilities use autogenous or semi autogenous grinding systems. Autogenous grinding uses coarse pieces of the ore itself as the grinding media in the grinding mill.
