Understanding Deep-sea Minerals and Ecosystems

Because of the rice of metal prices, there is a renewed interest for deep-sea mineral resources and their associated ecosystems. Explorative investigations conducted so far have resulted in a first estimate of the mineral resources and a better understanding of the benthic ecosystem. It was found that recovery of the fauna from previous small experimental mining simulations was very slow. Therefore, alternatives like recovery of metals from e.g. incinerated sludge are interesting (https://www.kwrwater.nl/en/projecten/recovering-metals-from-water-sludge-and-fly-ash/)....

Understanding Deep-sea Minerals and Ecosystems

Ifremer’s Explorations and Research France and Ifremer have had a long involvement in the discovery and study of deep-sea mineral resources and their associated ecosystems. With a rather unique position in the marine research landscape, Ifremer is actively involved in the deep sea, both as a contractor with the ISA and as an integrated marine science research institute. The HERMINE 2017 exploration cruise on the French polymetallic sulphides exploration contract is an example of combined mineral exploration and scientific investigations. In the seventies, France was amongst the pioneer nations that discovered the metal-bearing hydrothermal sources and explored the polymetallic nodule deposits in the Clarion Cliperton Fracture Zone (CCFZ) located in the northern central Pacific. A strong commercial interest for these potential sources of minerals initially triggered an important exploration activity by countries such as China, Germany, India, Japan, Korea, France, etc. Then, in the 1980s, unfavourable market conditions halted this exploration. The last two decades have seen a renewed interest for these potential sources of minerals sparked by factors such as the rise of metal prices, the development of low-carbon technologies increasing the demand for some minerals and geopolitical issues. Exploration of the three types of deep-sea mineral resources – polymetallic nodules, in...
