activated carbon has been the dominant process for gold extraction after leaching by cyanide in aerated alkaline slurries. The continuous processes of gold recovery by adsorption on activated carbon in agitated tanks, namely the carbon in pulp (CIP) and the carbon in leach (CIL) processes, have been widely used since the 1970s. Due to the economic

What Is the Difference Between Static and Dynamic Balance

Static balance refers to the ability of a stationary object to balance. It happens when the objects center of gravity is on the axis of rotation. Dynamic balance, on the other hand, is the ability of an object to balance while in motion or switching between positions. In humans, both types of balance are necessary to ensure an active lifestyle.

Difference Between Static Balance and Dynamic Balancing

However, the dynamic balance definition is the ability of an object to balance whilst in motion or when switching between positions. Undertaking in balancing whether it be static or dynamic can help to extend the service life, quality and accuracy of your machinery.
