Optimizing and evaluating the operational factors

In order to find the optimum conditions ofgoldleaching with the highest rate of extraction (gold recovery), numerical optimization was carried out using DX software, which is demonstrated in figure 7. It was found that the maximumgold recoverycould be obtained of approximately 91.5%, with a desirable value of 100%, by numerical optimization.
