  • Development of a comminution test method for small ore

    Kirpala (2013) tested the Bond and Mergan grindability tests with ten Finnish ore samples and concluded that, as a rule, the Mergan test gives slightly higher work index values than the Bond test. This purpose of this study was to extend the use and added value of the already existing Mergan grindability test for ore variability studies.
