/min. Key words: carbonic refractory gold ore; carbonate decomposition; pressure oxidation; ferric subsulfate dissolution 1 Introduction Refractory gold ores are characterized by low gold leaching ratio during direct cyanide leaching [1]. The gold in such so-called refractory ores is contained within sulphide minerals, such as particular pyrite and arsenopyrite present commonly in the form......
and gold mines contain sulfide ores with spontaneous combustion potential in China [2]. A fire disaster from the spontaneous combustion of sulfide ores in a mine can produce large quantities of toxic...J. Cent. South Univ. Technol.

for gold dissolution. The dissolution of gold in cyanide media is a heterogeneous process. The main problem in examining the dissolution of gold in the given medium including gold ores is determining... 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......
