含铜云母是赞比亚铜矿带地表氧化矿中一种主要的的难处理含铜矿物。为了有效提取含铜云母中的铜，本研究采用超声波助浸技术对含铜云母进行强化浸出。试验结果表明，相对于常规加温浸出而言，超声波助浸能够使浸出时间由120 min缩短为40 min，硫酸浓度由0.5 mol·L−1 降低为 0.3 mol·L−1。此外，当铜的浸出率都是78%时，浸出温度可由75°C 降低到45°C。超声波强化浸出机理研究结果表明，超声波能够对含铜云母进行有效剥离，使其比表面积由0.55 m2·g−1 显著增加到1.67 m2·g−1。该研究结果表明超声波助浸技术能够使含铜云母中的铜得到有效回收，同时对于从层状硅酸盐中提取有价金属也具有一定的参考价值。
Copper-bearing biotite is a refractory copper mineral found on the surface of the Zambian Copperbelt. Biotite is a copper oxide from which copper is extracted by various methods, especially by leaching. Leaching is the process of extracting a substance from a solid material dissolved in a liquid. To improve the efficiency of the leaching process by a more effective method, a new method called ultrasonic-assisted acid leaching is proposed and applied in this study. Compared with regular acid leaching, the ultrasound method reduced the leaching time from 120 to 40 min, and sulfuric acid concentration reduced from 0.5 to 0.3 mol·L−1. Besides, leaching temperature could be reduced from 75 to 45°C at the leaching rate of 78%. The mechanism analysis indicates that an ultrasonic wave can cause the delamination of a copper-bearing biotite and increase its specific surface area from 0.55 to 1.67 m2·g−1. The results indicate that copper extraction from copper-bearing biotite by ultrasonic-assisted acid leaching is more effective than regular acid leaching. This study proposes a promising method for recycling valuable metals from phyllosilicate minerals.
