可靠的金属供应历来是工业和技术发展的关键。但是,许多金属都有可能耗尽传统类型的矿床。这些金属包括锡、钨、银、铅、锌和许多其他金属,如果要继续供应,就需要从普通岩石中回收这些金属,在普通岩石中,这些金属以固溶体的形式存在于普通硅酸盐矿物中。从非常规资源中回收将是如此的能源密集型,以至于我们最终可能不得不停止开采这些金属。美国地质调查局在其第二个世纪面临的最大挑战将是资源有限的问题。
Reliable supplies of metals have historically been the keys to industrial and technological development. But many metals are subject to the possible exhaustion of traditional kinds of deposits. A continued supply of such metals, which include tin, tungsten, silver, lead, zinc, and many others, will require their recovery from common rocks, in which they are found in solid solution in common silicate minerals. Recovery from unconventional sources will be so energy intensive that we may eventually have to stop mining such metals. The greatest challenge facing the U.S. Geological Survey in its second century will be the problem of resource limitations.
