Bond Work Index an overview ScienceDirect Topics. The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWht required to grind to that size. Magdalinovic 38 measured the Bond work index of three ore types using different test screen ...
2020-1-3 A bench test was developed for dry grinding to determine the Bond work index and to know the PSD and hematite liberation in all the three iron ore product samples obtained from the BBM. For each iron ore sample, 700 cc of feed was weighed and added into the BBM.
The work indices of various iron ores in the world were measured. From the values of the work indices of the iron ores, the powers required to grind the iron ores were estimated. And thus, the grindability of the iron ores was investigated. The results obtained are as follows 1 The work indices of the iron ores are ranged from 6.22 to 17.40.

The work index of 20.39 Kwhs ton value obtained when granite was a reference ore is within the limit of work index of some iron ores in Nigeria Weiss, 1965 and Thomas, 2007. 4. CONCLUSION AND RECOMMENDATIONS The study shows that work index of Birnin Gwari iron ore can be taken as 28.66 Kwhston i.e.
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 Bonds 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 ...
