根据美国地质调查所(USGS)最近发布的报告,在本世纪资源不足的情况下,太平洋赤道的富锰结核金属、太平洋中部的富钴锰结壳和红海含金属的硫化物软泥等仅为深海的沉积物,似乎被认为是潜在的有经济价值的矿产.然而,只有到了矿物价格上涨,更有效的回收技术发展以及法律的和环境的问题得到解决以后,这些资源的开采才可能实 According to a recent report by the United States Geological Survey (USGS), at this century of scarce resources, the equatorial manganese-rich nodule metals in the Pacific Ocean, the cobalt-rich manganese crusts in the central Pacific and the sulfide-bearing slimes of the Red Sea metal are only Deep sea sediments appear to be considered as potential economically valuable minerals, however, exploitation of these resources is unlikely to be possible until mineral prices have risen, more efficient recovery technologies have been developed, and legal and environmental problems have been resolved
