%X Bond index is useful in designing of grinding system in mineral processing. In this study, the
Bond work index of Birnin- Gwari iron ore in northern Nigeria is determined using modified
Bond¡¯s method using ¡®reference ore¡¯. Samples of iron ore were sourced using random method,
reference minerals; marble and granite of known weight and iron ore of known weight were
ground using the laboratory ball mill grinding machine. 80% passing size for the iron ore
marble and granite samples were obtained at 100¦Ìm sieve size for the feeds and products. The
work index of reference minerals; marble and granite were used to calculate the work index of
iron ore. The value of 28.66 Kwh/short ton and 24.92 Kwh/short ton were obtained. The value of
20.39 Kwh/short ton was selected as it is within the range indicated by previous research work
on iron ore in Nigeria.
