摘要：

Fine coal cleaning by froth flotation has become common practice in the US with more than 73 kt/d (80,000 stpd) treated in this way. This paper attempts to evaluate several control strategies using a detailed flotation dynamic simulator, Dynafloat. After construction of a process matrix for the system of interest, promising alternatives for linking manipulated and controlled variables were analyzed. To develop combined grade and recovery control strategies, it was necessary to construct a grade/recovery map with the aid of the simulator to drive the system to known, final, feasible grade/recovery operating conditions. Finally, an advanced strategy that uses an on-line model to identify disturbances and take control actions is proposed.
