As well as, the Bond Work Index (BWI) and consumed power to grind one tone of iron ore were determined via standard Bond mill. The results showed that the ore is hematitic ore with Goethite and quartz minerals. The ore is low grade containing 41.41 % Fe2O3 and 50.88 SiO2. The bond work index test obtained high work index 52.60 kw.h/t and consumed power 11.72 kw.h/t to grind one ton of low grade iron ore and this attributed to the high concentration and hardness of quartz mineral which is considered the main gangue of the ore in study area.
