美国海尔金矿位于佐治亚州克省以北约5公里处。1942年以前,该矿是密西西比河东部地区最大的金矿,后来因故停采。美国政府调整黄金价格之后,海尔金矿成为美国东南地区首家恢复生产的金矿。在东南地区,该矿率先采用堆浸法。目前堆浸能力为1800吨/日矿石量。用碳作介质回收金。因为氧化矿石粘结和颗粒过细,堆浸前要用普通水泥造粒。造粒矿石的粒度达到50 The U.S. Haier Gold Mine is located about 5 kilometers north of the State of Georgia. Before 1942, the mine was the largest gold mine in the eastern part of the Mississippi River and was subsequently stopped for some reason. After the U.S. government adjusted the price of gold, Haier Gold Mine became the first gold mine to resume production in the southeastern United States. In the southeast, the mine pioneered the heap leaching method. The current heap leaching capacity of 1800 tons / day ore volume. Use carbon as medium to recover gold. Because the oxide ore and cement particles too fine, heaping before ordinary granulation with cement. Granular ore size of 50
