用Zadra法成功地预测金的洗脱效率,证明了以前提出的从活性炭上洗脱氰亚酸盐的动力学模型。根据这种模型解释了从实验室规模的固定床交换柱上洗脱获得的数据和在模拟的电积槽中金的萃取率。同时,研究了从未受重视的影响Zadra洗脱法效率的若干化学因素。在洗脱前用酸洗涤 The gold elution efficiency was successfully predicted by the Zadra method, demonstrating the previously proposed kinetic model for washing cyanate from activated carbon. According to this model, the data obtained from the elution on a laboratory-scale fixed-bed exchange column and the gold extraction rate in a simulated electrowinning cell are explained. At the same time, a number of chemical factors that have never been valued to affect the efficiency of Zadra’s elution were studied. Wash with acid before elution
