美国卡林黄金矿业公司用堆浸方法作为一般的金矿搅拌浸出和对流倾析法的补充处理方法。选择一露天矿,矿石品位为0.07唡金/吨。将矿石先破碎到3/4英寸,然后用载重汽车送到垫有沥青的场地上堆成堆,用稀氰化物溶液喷淋浸出七天。浸出液排出后,由前端装载机将废石运往尾矿池。大约有70%的金被浸出出来。堆的浸出液与对流倾析的富液一起,用锌粉置换法回收金。共设四个浸出场,每个能容纳1,400吨矿石。堆浸大约从每年四月开始,一直进行到十月,每月浸出10,000吨矿石。寒冷冰冻季节,堆浸停止进行。本文介绍了堆浸需要的劳动力,设备和药剂量。
The United States Carlin Gold Mining Company with heap leaching method as a general gold leaching and convection decantation method complementary treatment. Choose an open pit ore grade of 0.07 gold / ton. The ore was crushed to 3/4 inch and then piled on piles of asphalt with a truck for leftover days with a dilute cyanide solution. Leachate discharge, the front-end loader will be transported to the tailings pond waste rock. About 70% of gold is leached out. The heap leachate and convective decantation of the rich liquid together with zinc powder replacement gold recovery. A total of four leaching fields, each capable of holding 1,400 tons of ore. Heap leaching starts approximately every April and runs until October, leaching 10,000 tons of ore per month. Cold and freezing season, heap leaching stops. This article describes the labor, equipment, and dose requirements for heap leaching.
