而大于3岁t的矿石送到常规选厂处理，这样整个矿山形成一个“闭路循环”系统。常规厂的废液添加少量氰化钠，使其浓度达到堆浸喷淋要求后，就可输送到“堆浸”场地进行喷淋。“堆浸”后的贵液送到常规厂中的“CIP”车间即炭浆车间，统一回收金。这种生产系统的矿山，往往先建" CIP"车间及“堆浸”场，以后逐步建设其他生产系统。矿山在建设的当年即可生产出黄金，大大提高投资的回收。这种生产方式是值得我国借鉴的。

The ore is sent to more than 3 years old t conventional processing plant processing, so that the entire mine to form a "closed loop" system. After adding a small amount of conventional sodium cyanide plant effluent to a concentration of heap leaching sprinkler requirements, can be delivered to the "heap leaching" venues spray. "Heap leaching" after the precious liquid to a conventional plant of the "CIP" workshop namely CIP workshop, unified recovery of gold. This mine production system, often the first to build "CIP" workshop and "heap leaching" field, after the gradual build other production systems. Construction of the mine in the year can produce gold, greatly improving return on investment. This mode of production is worth our reference
