Potential-controllable green gold extraction method for carlin-type gold ore

The invention discloses a potential-controllable green gold extraction method for carlin-type gold ore. The method comprises the following steps: taking perchloric acid as a gold leaching agent, carrying out gold leaching treatment on the carlin-type gold ores in a slow and continuous adding manner under the condition that the potential and the pH value are controllable, and finally recovering gold from a leaching solution through a conventional gold extraction process. The method has the advantages that the gold extraction process is environmentally friendly, the gold leaching rate is high, and corrosion to equipment is small; and in addition, the method also has the characteristics of high gold leaching rate and low gold leaching cost. 本发明公开了一种可控电位的绿色的卡林型金矿提金方法，是以高氯酸为浸金剂，在电位及pH值可控的条件下，通过缓慢连续加入的方式对卡林型金矿进行浸金处理，最后浸出液通过常规提金工艺回收金即可。本发明具有提金过程绿色环保，金浸出率高，对设备腐蚀性小的特点；此外，本发明还具有黄金浸出率高，浸金成本低的特点。
