Abstract
A model is proposed for the simulation of mineral separation plants using linear programming. A mineral separation plant is described here by two linear models, one being a subset of the other. These models are solved in succession, the first producing the total flow rates between the banks and the circuit configuration, and the second the flow rates of mineral species. Circuit configurations produced by the simulation model are similar to those encountered in industry. This suggests the feasibility of applying the model in the design of separation plants in practice. The grades and recoveries obtained also closely resemble those of similar separation plants in industry. The only data required by the simulation models are the separation characteristics, tailings grade constraints and the feed rates. © 1988.
