This article focuses on the use of a model in combination with economic analysis to extract maximum value out of current gold operations, without the need for additional capital. Two South African case studies (CIP and CIL) are presented to show that an optimum point of operation exists. This optimum point of operation, however, depends on several economic factors such as the gold price, exchange rate, and utility costs in combination with plant conditions such as the feed rate and Au grade. As these parameters fluctuate, the operating conditions will have to be adjusted to achieve the maximum value. Operating at a maximum will require regular decision-making and adjusting of operating conditions, especially in times of a constrained economy.

Keywords : gold recovery; optimization; CIP; RIP; economic; analysis; modelling.
