  • Optimizing and evaluating the operational factors

    In order to find the optimum conditions of gold leaching 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 maximum gold recovery could be obtained of approximately 91.5 with a desirable value of 100 by numerical optimization.
