深海多金属结核开发技术研究的现状

在世界各大洋中,大约有15％的深海底被含锰、镍、钴、铜等76种元素的多金属结核(又称锰结核)所覆盖,它将成为人类未来所必需的自然资源。国外发达国家和一些较发达国家从60年代起开始进行这一资源开发利用的研究。我国现也开始这方面的研究工作。本文简要介绍深海多金属结核资源及国内外进行开采技术研究的情况。

CURRENT STATE OF TECHNOLOGY FOR DEEP-SEA POLYMETALLIC NODULE EXPLOITATION

In the occeans worldwide, about 15% deep-sea floor is coverd with polymetallic nodules ( or known as manganese nodules ) containing 76 elements such as manganese, nickel, cobalt and copper. These nodules, undoubtedly, will be an essential natural resource for mankind in the future. Since the 1960's, some developed countries have began researching into the exploitation and utilization of the natural resource. More recently , China also started on research work in the field.In this paper, deep-sea manganese nodule resource is briefly described along with state-of-the-arts of exploition technologies both at home and abroad.
