is necessary to determine the optimum conditions for modeling of gold leaching in cyanide media. Many researchers studied on dissolution and modeling of gold ores cyanidation [1-8]. Artificial neural network... with the experimental results, as shown in Fig.6. It is indicated that model of ANN exactly reflects the correlation between the input and output layers. The function of gold cyanide leaching parameters......
