Thickener Optimization In Your Mining Process

The thickening process is a fundamental step in modern mining separation processes. Thickening is the separation of suspended particles from a liquid by gravity settling. For effective thickener control, six measurements are critical bed mass inventory, bed level, underflow density and flow, flocculent dosing and overflow clarity.
