3- STANDARD BOND TESTS The Bond'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

Internationally accepted mineral metallurgical standard test procedures to determine the physical properties of ores include the Bond ball mill work index. This is empirical index determined by closed circuit grindability tests developed by F.C.Bond in the mid 1930's.

micrometers in size. 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 -3.327 mm.

The optimum number of grinding balls is 285. However, the ball diameters vary due to wear. Therefore, the total ball number should be adjusted from time to time to ensure a total mass of 20.125 grams. The grinding jar of the Bond Index Ball Mill measures 12″ x 12″ and has well-rounded corners. Module Rod Mill

be used to calculate Mergan work index, but this Mergan work index differs from the Bond work index. Therefore, it is needed to analyze if the Mergan work index correlates with Bond work index. All the testwork was conducted using Outotec Mergan and Bond ball mills at Outotec Research Center, located in the city of Pori, Finland.

grindability is Bond's work index which is defined as the resistance of the material to grinding.

P G P F W i bg i u (4) In designing and optimizing a milling circuit using Bond

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
