The Laboratory Comparative Work Index gives an approximate Bond Work Index for an ore sample. This can then be used with Bond’s Third Theory of Comminution to calculate net power requirements needed for grinding. The test depends on laboratory batch grinding and uses a comparison with the grinding of an ore of a known Bond Work Index.
This test is used where insufficient material is available or the sample is not coarse enough for a Bond grindability test. The feed sample requirements depend on the size of mill and the amount of material available.
