A systematic review of sustainable gold extraction from raw ores …
The highest Fe-bearing gold ore was the most difficult to extract Au in ETU/TU leaching. There are at least two detrimental factors in TU leaching of Fe-rich gold ores, that is (i) the oxidative decomposition of TU, and (ii) complexation of TU with Fe 3+, which both cause to deduce the complexation of TU with Au +.
