  • Thiosulfate leaching of goldA review ScienceDirect

    Thiosulfate leaching can be considered a non toxic process, the gold dissolution rates can be faster than conventional cyanidation and, due to the decreased interference of foreign cations, high gold recoveries can be obtained from the thiosulfate leaching of complex and carbonaceous type ores. In addition, thiosulfate can be cheaper than cyanide.
