摘要 进行了银对闪锌矿氧压酸浸催化作用的研究。通过间歇性小型试验考察了各种因素对浸出率的影响,诸如浸出温度、浸出时间。试验在2升的高压釜内进行,结果表明银离子对闪锌矿氧压酸浸有显著的催化作用。 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.
