Mineral dressing (= Orebeneficiation)

Primary Crushing (coarse crushing): In primary crushing, ore or run-of-mine ore (up to 1 m in size) is crushed down to about 10 cm and it is done in a jaw or gyratory crusher. – ii. Secondary Crushing (intermediate crushing): In this case, ore is crushed from 10 cm to less than 1 –2 cm size; for this purpose jaw, cone or roll crushers are used.
