Effect of arsenopyrite on thiosulfate leaching of gold

open access: yesTransactions of Nonferrous Metals Society of China, 2015
Abstract Arsenopyrite was artificially added into the thiosulfate leaching solution to clarify the role of arsenopyrite on the thiosulfate leaching of gold. The effect of arsenopyrite on the thiosulfate leaching of gold was studied by the thermodynamic calculation, mineral dissolution test, leaching test and XPS analysis.
