随着人们对金的氰化浸出机理研究的深入,氧在金与氰化物反应形成金氰络离子过程中发挥的重要作用得到了认识,并进而引起人们在氰化生产实践中应用这一原理的极大兴趣,近年来,用提高矿浆溶解氧浓度来加快金银溶解速率的实验和实践情况,国外已有许多报道,最近,中国有色金属矿业实验中心受国家黄金局及张家口金 With the deepening of the research on the cyanide leaching mechanism of gold, the important role of oxygen in the reaction of gold and cyanide to form gold cyanide ions has been recognized, which leads to the application of this principle in cyanide production practice Great interest in recent years, with increasing the concentration of dissolved oxygen to accelerate the dissolution rate of gold and silver experiment and practice, there have been many reports abroad, recently, China Nonferrous Metals Mining Experimental Center by the National Gold Council and Zhangjiakou gold
