| 摘 要： | 对采用超声波和非超声波两种条件作用下原位电化学生成氧化剂浸取难处理金矿进行了研究.结果表明:采用超声波能够显著地提高金的浸出率,且缩短浸取反应时间.在没有超声波条件下采用原位电氯化法浸取6h,金的浸出率为54.84%;但在超声波作用下,金的浸出率可达90.68%.另外,通过对浸取前后矿渣的XRD图谱比较可知,没有使用超声强化的电氯化浸取后矿渣表面检测到元素硫,而用超声作用的矿渣表面则没有检测到硫.并由此分析了超声波对金矿浸出的作用机理和对电极反应的影响. |
| 关 键 词： | 难处理金矿 超声波 电氧化法 浸出率 |

| Abstract: | Oxidant was prepared by the method of electrochemistry in situ leaching gold from refractory gold ores under the ultrasonic-aided and un-ultrasonic-aided conditions. Result show that the application of ultrasonic condition greatly increases the leaching rate and shortens the reaction time while the conventional cyanide method is adopted, the gold leaching rate after leaching 24 h is only 25% of the refractory gold ores. In the equal conditions, under the un-ultrasonic-aided in situ leaching conditions the l... |
