海洋锰结核是覆盖在深3000～6000米海洋底面上的矿物资源。其中主要含有锰、镍、铜、钻等几十种有价金属。据资料统计,在全世界3.62亿平方公里(占地球面积三分之二以上)的海底总面积中,大约有15％为锰结核所覆盖,总储量约为2～3万亿吨(仅太平洋就占1.7万亿吨)。作为工业储量约为230亿吨,其中镍2.9亿吨,铜2.4亿吨,钴0.6亿吨,锰60亿吨。此外,在8000英尺(2438.4米)深的厄瓜多尔加拉帕戈斯群岛附近海底还发现了含铜10％、铁35％、锌7％的2000万吨铜铁硫化矿床。
Marine manganese nodules are mineral resources that cover the deep ocean floor of 3000-6000 meters. Which contains mainly manganese, nickel, copper, dozens of drilling and other valuable metals. According to statistics, about 15% of the total undersea area of 362 million km2 (accounting for more than two thirds of the earth’s surface) of the world is covered by manganese nodules with a total reserves of about 2-3 trillion tons Accounting for 1.7 trillion tons). As an industrial reserve of about 230 million tons, of which 290 million tons of nickel, 240 million tons of copper, 60 million tons of cobalt and 6 billion tons of manganese. In addition, a 20 million tonne copper-iron sulphide sulfide deposit containing 10% copper, 35% iron and 7% zinc was also found on the seabed near the Galapagos archipelago of 8,000 feet (2,438.4 meters) deep in Ecuador.
