SIMULTANEOUS OPTIMIZATION OF FLOTATION

2016-5-17  practical knowledge in relation to column design, structure, operation, optimization, and control. Flotation processes are difficult to optimize at a fundamental level, and at present automatic monitoring and control of industrial plants have met with limited success. Practically, these processes are most often controlled by human operators who tend to evaluate the performance of the plant based on their own experience and other heuristic rules. Full potentials of plants are usually not used optimally, owing to lack of experience on the part of the operators, human error, etc. Indeed, considerable variation is sometimes observed between different shifts, or during different times of the day. These operational instabilities are considered to play a significant role in the cost-effective operation of flotation plants.
