A procedure for rapid determination of the Bond work index

The grindability of an ore in the process of mineral dressing can be determined by use of the Bond work index (Wi). This index is determined on a laboratoryscale using a Bond ballmill and by simulating dry grinding in a closed circuit until the 250% circulating load has been obtained. This happens only after 7–10 grinding
