Abstract: This paper represents a plant optimization (capacity improvement) study for a gold heap leach plant to obtain the product size of of -6 mm crushed ore at a capacity of 180 Mg/h. The former plant flowsheet was re-designed to obtain the target product size and capacity by modeling and simulation.
People have always tended to regard the crushing and screening section of a flowsheet involving grinding mills simply as a function of feed preparation for those mills. Consequently, in most operations, crushing plant opera- tors produce mill feed as fast as possible. But the fastest feed rate produces the coarsest material, causing any sub-
