Table I shows the Bond ball mill work index obtained for the ore samples as well as the iron and silica content in concentrate and tail after LIMS. The concentrate weight recovery was in the order of 50–60%. Furthermore it may be observed that the Bond ball mill work indices for the ore (Wi) varies from 14.6 to .
Generally, Bond work index is a common method for selecting comminution equipment as well as estimation of grinding efficiency and calculating required power. In the current research, a simple, fast and accurate procedure is introduced to find the
Their proposed model against the traditional Bond rod-mill work index had a standard deviation below 10%. The objective of this study was to conduct a rapid determination of Bond work index by considering grinding kinetics of the particles in standard Bond rod-mill as well as size-mass balance equations in the mill.
Bond index is useful in designing of grinding system in mineral processing. In this study, the Bond work index of Birnin- Gwari iron ore in northern Nigeria is determined using modified Bond's method using 'reference ore'. Samples of iron ore were sourced using random method, reference minerals; marble and granite of known weight and iron ore of known weight were ground using the ...

The work index of 20.39 Kwh/s ton value obtained when granite was a reference ore is within the limit of work index of some iron ores in Nigeria (Weiss, 1965 and Thomas, 2007). 4. CONCLUSION AND RECOMMENDATIONS The study shows that work index of Birnin –Gwari iron ore can be taken as 28.66 Kwh/ston i.e.
bond work index and grind size iron ore grinding mill china. The work index (Wi) has been obtained for the sample of iron and copper ore following both the standard Bond procedure and the abbreviated procedure as described in this paper a procedure has been developed for the rapid determination of the work index (Wi) by means of just two grinding,
can be created based on grinding time and bond work index values. To do that, an iron sample was used in different experiments. In next step, the defined equation is applied to estimate the selection function and energy efficiency. In addition, relationships between bond work index values and some variables are investigated as
Fred Bond is being inducted into the International Mining Technology Hall of Fame in the comminution category for 2015. The word Bond is synonymous with grinding circuit design, e.g. Bond Grindability and Bond Work Index.
Based on the defined first-order grinding kinetics in the Bond ball mill, a procedure has been developed for the rapid determination of the work index (Wi) by means of just two grinding tests. The applicability of the proposed abbreviated procedure has been proved on samples of copper and iron ore.
ore. Some these tests include Bond Work index tests, SAG Power Index tests (SPI), and JK grind tests. The information from the grinding work can provide an estimate of the energy requirements for a prospective plant and an understanding of the ore variability. Preliminary grinding flowsheet development can be leveraged from this type work.
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.
