As an ore comes from the mine it is desirable to eliminate at once the gangue. This may be done more or less successfully with some ores by simple handpicking methods, while other ores must be crushed in a stone breaker or stamp mill, and the gangue eliminated from the finely crushed mass by dressing, which consists of passing running water over the mass in a succession of boxes so that the ...

The comminution is an important unit operation in mineral processing, this process requires appliion of forces. Mechanical comminution can be accomplished in mainly 2 ways. 1. Crushing: the most used crushing machine are the jaw crusher, cone crusher, impact crusher, and hammer crusher. 2. Grinding: crushed material can be further ground in grinding mills like ball mill, rod mill, hammer ...
· Coal gangue ceramsite is processed from coal gangue produced in a coal mine in the Shenmu area (Shaanxi province, China), with a particle size of 4–8 mm, the apparent density of 1650 kg m −3, the water absorption rate of %, and crushing index of %.
The process used at a mine to separate fine particles of valuable metal from gangue. Finelyground ore is slurried and passed through cells where agitators and chemicals cause the metal to rise to the surface, where it is recovered from the overflow, dried and sent to the smelter.
