而大于3歲t的礦石送到常規選廠處理，這樣整個礦山形成一個“閉路循環”系統。常規廠的廢液添加少量氰化鈉，使其濃度達到堆浸噴淋要求后，就可輸送到“堆浸”場地進行噴淋。“堆浸”后的貴液送到常規廠中的“CIP”車間即炭漿車間，統一回收金。這種生產系統的礦山，往往先建" CIP"車間及“堆浸”場，以后逐步建設其他生產系統。礦山在建設的當年即可生產出黃金，大大提高投資的回收。這種生產方式是值得我國借鑒的。

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
