美国内华达州圆山附近的烟谷(Smoky Valley)金矿,位于尼县托诺帕以北96km处。工厂基建总投资1800万美元,经两年建成于1977年投产,当年产金1.152t。该厂有职工140人,预计1979年产金1.71t,银0.98t。
该矿有按含金边界品位0.68g∕t固定的矿石储量1200万t,矿石平均含金1.93g/t、银2.18g∕t。使用氰化液堆浸,金的回收率达86%。
矿山为露天开采,采出的原矿经1066×1651mm的圆锥破碎机碎至178mm后,由宽914mm的皮带运输机供入2.1m西门子(Symons)标准破碎机再破碎至-50mm,然后由两台2.1m西门子短头破碎机碎至-9.5mm供堆浸用。
