美国帝国县的金地迈思科特矿由于能够有效地处理低品位矿石,其处理能力从1986年的210万吨/年增长到现今的730万吨/年。为了满足增加处理能力的需要,在1989年进行堆浸衬垫的建设并投入了生产,以完善现有的堆摊浸生产,这就提供了可以在同一生产过程中对两种处理方法进行比较的一个最佳时机。通过提高回收率(即使矿石品位很低),尽管增加了与碎矿有关的生产费用,业已证
Due to its ability to treat low-grade ore efficiently, the Meisecott Mine in the Empire County of the United States has increased its processing capacity from 2.1 Mtpa in 1986 to 7.3 Mtpa / year. In order to meet the need for increased processing capacity, the construction of a leach pad in 1989 and its commencement of production to perfect the existing heap leach production provided a way to compare the two treatment methods in the same production process One of the best time By increasing recovery (even if the grade of the ore is low), despite the increase in production costs associated with crushing ore,
