| Abstract |
Ammonium thiosulphate was chosen as lixiviant and various tests were performed to find optimum leaching conditions in extraction of gold from a gold ore. Parameters investigated were pH, temperature, amount of lixiviant, pulp density and stirring rate. Catalytic effect of cupric ion was evaluated. Apparent activation energy of the leaching reaction was found to be 58.4 kJ/㏖ and the rate was controlled by the chemical reaction |
