众所周知,对于资源较小的公司,用堆浸技术回收责金属是一种有生命力的方法。而露天开采贵金属的堆浸回收比常规采选方法更为低廉。常规的采选冶方法需要大量基建投资。因为:寻找和勘探直至有效益地开采回收费用高;获得政府许可开采所花费的时间长;矿山场地、生活设施的准备应在矿山或其附近;基建、生产的前期准备工作时间长;需要考虑提供一个安全的工作环境,特别是地下开采;必需考虑地区环境保护。然而,使用堆浸法可解决以上问题。例如:(1)在北美场地准备和矿山建造费用对于
As we all know, for smaller companies, heap leaching technology to recover the responsibility of metal is a viable approach. Open pit mining heap leaching recovery than the conventional mining methods cheaper. Conventional Mining and Metallurgical Methods require substantial capital investment. Because: to find and exploration until the cost of effective recovery of mining; government permission to obtain the exploitation of a long time; mine site, living facilities should be prepared in or near the mine; infrastructure, production preparatory work for a long time; need to consider Provide a safe working environment, especially underground mining; must consider the regional environmental protection. However, using the heap leach method solves the above problems. For example: (1) Venue preparation and mine construction costs in North America
