The simulation of ore-dressing plants - ScienceDirect

Apr 01, 1984  Pederson and Gurun (1970) and King (1975b) discussed the techniques of simulation of ore-dressing plants, though not in detail. Although much effort has been expended in the development of mathematical models of ore- dressing operations, simulators that treat either only comminution or only flotation are the only ones available.
