Abstract
This project was devoted to reach two aims: (i) to optimize the gold leaching process
based on ammonia thiosulfate and catalyzed by copper as a novel leaching agent, and (ii) to develop
the cyanide recycling technology. Alternative technologies such as Acidification-Volatilization-
Reneutralization (AVR), Sulphidization, Acidification, Recycling and Thickening (SART) and Gas
Membrane technologies were compared and considered for further development.
