A prototype expert advisor was developed by the Bureau of Mines to systematically offer advice on the control of a Florida phosphate operation. The personal-computer-based system receives input from remote sensors for circuit parameters such as feed rate, reagent addition, and ph and from operator-entered information such as the quality of the concentrate and tailings in each of the coarse, fine, and amine flotation circuits. The computer evaluates the information using rules obtained from industry representatives and Bureau flotation experts. Recommended actions and questions are displayed to quickly guide the operator to a problem within the flotation circuit and suggest a solution. This process control system could provide more uniformity among the flotation operators and also serve as a trainer for new operators. In addition, it represents a step toward fully automated systems for phosphate flotation.
