of ore samples to AG/SAG grinding. The pilot plant can test coarse feeds (150mm), as well as essentially any test conditions, so it presents the lowest degree of scale-up within all the methodologies available, but pilot testing is also the most expensive test, as it requires the greatest sampling effort, in the form of bulk samples or large
Although new applications on new ores ideally should be studied by a pilot plant test of a 50-ton sample, if the ore resembles ore previously tested, it is possible to make confident mill selections on very small ore samples. No one has developed an autogenous mill selection method comparable to the Work Index Method for selection of …
