Definition Of The Grindability Of Ore

measurements of varying ore grindability. Energy efficiency can be a simple ratio of the specific energy in the plant to the specific energy predicted by the work index. Different versions of the prediction exist; one example is the Bond efficiency of industrial grinding circuits (Burke, J. M. [Ed.], 2015).
