Fault 1: The mining ball mill makes loud noise. Reason: One of the reasons for loud operating noise may be unbalanced load distribution in the mill. Uneven distribution of material may cause uneven grinding media wear or excessive vibration, resulting in additional noise. Another possible cause could be worn or damaged bearings, which can cause ...

Gold Gravity Separation. The gravity separations are simple and separate mineral particles of different specific gravity. As the density of gold mineral is much bigger than gangue mineral, for the gold mine which has gold particles people often use the gravity separation process. Gravity concentration is a proven process for mineral beneficiation.
