The first step of physical beneficiation is crushing and grinding the iron ore to its liberation size, the maximum size where individual particles of gangue are separated from the iron minerals. A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure (based on Ref. [4]).This type of flow sheet is usually followed when the crude ore contains below 30% iron.

: Beneficiation. Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue.

The process is continuous and it is done on a large scale—103 to 10 5 tonnes of ore feed per day. Beneficiation is begun with crushing and wetgrinding the ore to typically 10100μm. This ensures that the copper mineral grains are for the most part liberated from the worthless minerals.
