China Seabed Mineral Exploration Identifies 30 cm Cobalt Crust

On September 11th, local time, the “Ocean No. 6” ship of the Guangzhou Marine Geological Survey, which is conducting the scientific research task in the cobalt-rich crust contract area of ​​the western Pacific (2.220, 0.04, 1.83%), was sampled by deep sea shallow drilling to obtain the crust. Core sample with a thickness of 33 cm. It is reported that this is the core sample with the largest crust thickness obtained since the investigation of sea-cobalt-rich crust resources in China in 1997.

Cobalt-rich crust is a kind of “shell-like” sedimentary mineral mainly grown on seamount hard rock. It is rich in cobalt, nickel, copper, manganese, platinum, rare earth and other metal elements. The “cobalt” content is particularly significant. One of the most strategic economic mineral resources of the modern ocean. The growth of cobalt-rich crusts is extremely slow, with an average of only a few millimeters per million years of growth. Due to the extremely low growth rate and stable formation environment, cobalt-rich crusts have been considered by the industry to be natural samples that track changes in the paleo-ocean environment from millions of years to millions of years.

In the core samples obtained from the survey of ocean voyages in China over the years, the thickness of the crust is usually several centimeters to ten centimeters, and the number of shells is less than 20 centimeters. The “great thick” cobalt-rich crust samples obtained by Hainan in the contract area Haishan indicate that the resource potential of this area is huge, which has very important scientific research value for studying the cobalt-forming crust mineralization mechanism.
