Semi-autogenous grinding after calcination generated significantly more fines than autogenous grinding or crushing after calcination in the case of the PF sample. The energy consumed during the bond ball mill work test of the calcined ores was 42% less than that of the non-calcined ores. It must be noted that the reduction in comminution energy

In autogenous grinding, a distinction is made between ore and ore-pebble grinding. Ore grinding is carried out in mills with a large diameter (up to 12 m) and short length (the ratio of diameter to length is approximately 3). Ore with pieces having dimensions up to 300 mm (sometimes, up to 600 mm) is loaded into the mill.
