Fast and Effective Gold Leaching from a Desulfurized Gold Ore
The gold extraction percentage and the weight loss percentage of the sample were 97% and 8.8%, respectively, under these optimal conditions. Gold leaching by this method was very fast and effective, and the temperature was low. These characteristics made it possible to apply this method in continuous operation mode in industry. Cited By
