Mineral Resources from the Ocean |

Mineral Resources from the Ocean Oceans cover 70 percent of Earth's surface, host a vast variety of geological processes responsible for the formation and concentration of mineral resources, and are the ultimate repository of many materials eroded or dissolved from the land surface. Hence, oceans contain vast quantities of materials that presently serve as major resources for humans.

List of Minerals Found Under the Sea Bed |

The sea bed, also known as the ocean floor, is composed of different minerals than what is found in the uppermost section of earth's surface. The ocean floor itself is made of mafic rocks, the crystallized matter from silicate magma. The seabed is also home to Volcanic Massive Sulfide deposits, which are rich in ore that can be mined for its resources. Minerals found under the seabed include

Mining the Oceans: Can We Extract Minerals

The oceans are vast and contain immense amounts of minerals which, in principle, could be recovered without the need of digging, crushing, processing, and all the other complex and energy expensive procedures that we need for mining on land. Indeed, the extraction of minerals from seawater is a concept that periodically reappears in times of energy crisis. It had become popular with the first
