Control strategies for flotation circuits - Rhosonics

2021-2-12  Flotation is about recovery of valuable materials and is known as a complex process that is affected by multiple factors. The circuit performance (grade and recovery) is strongly affected by those factors. Stabilisation is needed to ensure consistent circuit performance. Instrumentation is a key part of it, since those instruments obtain real-time data on the processes to be used in control ...
