Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of

The grindability experiments was carried out on the four typical samples of copper, lead–zinc, manganese and iron ore in specified time periods in order to model the standard Bond rod-mill test. The plot of cumulative oversize versus grinding time for various test-sieves revealed that the grinding of test-sieve oversize fraction in the Bond rod-mill follows the law of first order kinetics

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors..

Experience from Tennessee Copper confirms that rod consumption is directly proportional to mill speed. Some of reported operating data is conflicting, but reduction in media consumption per unit power with higher mill speeds is also observable in ball mills. At first glance, this conflicts with Bond’s (1963) suggestion that metal wear per unit power is the correct criteria to rate ore
