据南朝鲜科学技术处官员披露,南朝鲜当局最近拟定一项有关开采太平洋海底锰矿的计划。初步划定的海上矿区有两片,均位于夏威夷东南海域,总面积为七五○○○平方公里.这两个海区的平均水深为三○○○米,南朝鲜已在海底表层采到部分卵状的矿石.经分析,含有大量锰、镍、钴等稀有金属成份.总储量约有一亿吨.开采工作计划分为三个阶段进行.第一阶段为一九八九年至一九九二年,主要任务是,建造一艘海洋勘测船(一一○○吨级),对上述海区进行精密勘探.第二阶段为一九九三年至一九九九年,主要任务是研究解决海上开采、运输和冶炼的技术问题.第三阶段,是从二○○○年起,以每年三○○万吨的数量投入开采,年产值约一
Officials from South Korea’s Science and Technology Agency disclosed that the South Korean authorities recently devised a plan for the exploitation of manganese ore in the Pacific Ocean. There are two preliminarily designated marine mines, both located in the southeastern area of Hawaii with a total area of 75,000 square kilometers. The average depth of the two sea areas is 3,000 meters, and South Korea has taken part in the surface of the sea floor Oval ore.After analysis, contains a lot of rare metals such as manganese, nickel, cobalt, etc. The total reserves of about 100000000 tons.The mining work plan is divided into three stages.First stage for the 1989 to 19 The main task in 1992 was to construct a marine survey vessel (1,100-tonne class) for precision exploration of the above sea areas. The second phase, from 1993 to 1999, focused on research To solve the technical problems of offshore mining, transportation and smelting, the third phase started from 2000 onwards with an annual output of 30,000 tons and an annual output value of about one
