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。 About 15% of the deep ocean floor in all oceans in the world is covered by 76 types of polymetallic nodules (also called manganese nodules) containing manganese, nickel, cobalt and copper, which will become the natural resources necessary for the future of mankind. Developed countries and some more developed countries from the sixties onwards to carry out the development and utilization of resources research. My country is also now beginning research work in this area. This article briefly introduces the resources of deep-sea polymetallic nodules and the research on mining technology at home and abroad.
