Proper flotation cell level control is one of the most important yet overlooked parameters in a mineral processing plant, especially in new plants, says XPS Process Control. Upstream flow disturbances, improperly sized actuators, poor controller tuning, including dead time between control actions and responses, and improperly selected/commissioned instruments all contribute to the problem in ...
