ABSTRACT:
A process for extracting gold from a gold-bearing ore. The process includes, first, providing a leaching liquor with thiosulfate anion and ethylenediamine. Next, the leaching liquor is contacted with the gold-bearing ore to form a pregnant leach solution including gold dissolved from the gold-bearing ore. Finally, at least part of the gold in the pregnant leach solution is recovered.
