processing industries are mostly of the tumbling mill type. These mills exist in a variety of types rod, ball, pebble autogenous and semiautogenous. The grinding action is induced by relative motion between the particles of media the rods, balls or pebbles. This motion can be characterized as collision with breakage induced primarily by impact or as rolling with breakage induced primarily ...

Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral (Chapter 12). Take care to ...
The original design for the processing plant involved ore from the mine being conveyed to a 150t surge bin before grinding in a fully autogenous mill. This mill was converted during 2005 to semiautogenous, allowing the plant to handle harder ore as well as increasing the plant throughput to around 1Mt/y. "In 2009, Raglan produced of ore milled containing 29kt nickel in concentrate ...
