Overgrinding In Grinding Circuits

Overgrinding In Grinding Circuits

A significant cause of overgrinding is when an ore contains minerals of different densities and a hydrocyclone or other classifier is used to control product size from the circuit grinding the ore the most important case of this is iron ore grinding where the iron oxides have densities of approximately 5 gcm 3 whereas the gangue minerals
