Catalytic Role of Silver in Acid Pressure Oxidative Leaching of Sphalerite Concentrate

An attempt was made to investigate the catalytic role of silver in enhancing the rate of acid pressure oxidative leaching of sphalerite concentrate.A series of batch experiments were performed under various conditions to investigate the influences of variables,such as temperature and duration.The experimental results obtained show that as a catalyst,aqueous silver ions can accelerate the leaching of sphalerite concentrates significantly.
