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 using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, …

According to the Bond standard procedure, the work index is determined by simulating a dry grinding in a closed circuit in the Bond ball mill to achieve 250% circulating load (Bond, 1949, 1952, 1961). The test is performed on a raw material approximately weighing 10 kg, which coarseness is 100% -3.327 mm.

Although population standard deviation should be used in the computation, it is seldom available, and as such a sample, the standard deviation is used as a proxy for population standard deviation. Mathematically, it is represented as,
Green Bonds are standard bonds with a bonus "green" feature. The green "use of proceeds" bond market has developed around the idea of flat pricing - where the bond price is the same as ordinary bonds. Prices are flat because the credit profile of green bonds is the same as other vanilla bonds. from the same issuer.
We view this as an important component of our green bond evaluation. Blackrock has been a strong supporter of World Bank Green Bonds in the past, and this pioneering work on reporting standards was a key factor behind our …
The Bond work index, W i, is defined in a Bond ball mill on the samples of standard size − 3.327 + 0 mm. In practice, it is possible to find materials of non-standard size that are finer than 3.327 mm.. In this work, a procedure for the calculation of the Bond work index is suggested for cases when the Bond grindability test is conducted on samples of non-standard size.
