The deep sea is the largest biome on Earth. It makes up 90% of the marine environment and plays a vital role in regulating our planetarysystems, not least by absorbing and storing vast quantities of the carbon dioxide emitted into the air by human activity.

Alluvial mining involves the building of walls and the diversion of rivers. Once the water is emptied out and prevented from flowing into the area of interest, bulldozers are then used to exploit the ground of the riverbank. Usually, kimberlite ore can be found in depths of at least 15 meters. When the diamond-rich depth is reached, the raw ...

Overview. Deep Sea mining, like asteroid mining, is a relatively unconventional method of extracting Rare Earth elements (REEs). Unlike asteroid mining, however, deep sea mining has already been undertaken through projects such as deep sea diamond mining. Actual mining for REEs has not been attempted because of environmental issues and cost.
