The Bond’s work index has generally been accepted as a measure of the grindability of an ore. This study used quartz as a reference ore via a comparative method to determine the Bond’s work index of Baban Tsauni Nigeria ore.
that the Bond CWi and the standard Bond BM Wi both recorded average values of 8 kWh/t it was surprising that the Bond Rod Mill Wi average was 11.3 kWh/t. Since the ore is unusually soft the Rod Mill Wi is probably irrelevant in determining required power for the SAG mill. Drop Weight Tests
The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example the finer the grind size desired the higher is the kWh/t required to grind to that size. Magdalinovic 38 measured the Bond work index of three ore types

The Bond Abrasion Test determines the Abrasion Index which is used to determine steel media and liner wear in crushers rod mills and ball mills. Bond developed the following correlations based on the wear rate in pounds of metal wear/kWh of energy used in the comminution process.
The Bond& 39;s standard ball mill is used to determine the work index value of differ ent samples. The Bond work index is defined as the kilowatt-hours per short ton required to break from infinite size to a product size of 80% passing 100 µm. If the breakage characteristics of a material remain constant over all size ranges the calcul ated work
To determine the optimum allo ion to gold it is useful not only to compare gold with other commodities but also to consider the broader impact that gold can have on portfolios. The World Gold Council has conducted analysis based on typical US investment portfolio allo ions of varying risks and back-tested the ideal allo ions of gold
