Here’s what you need to know about the deep-sea gold rush

 · Collecting deposits near hydrothermal vents: When hot water spewing from hydrothermal vents hits the surrounding cold water, minerals and metals dissolved in the hot water condense and fall to the seafloor. Remote-controlled vehicles collect these deposits (usually copper, gold and silver) and pipe them up to the surface.

Treasures of the Deep: Tapping a Mineral-Rich Ocean Floor

 · Deep in the Pacific Ocean, blasts of minerals resemble plumes of smoke. Cold seawater trickles through cracks in the Earth’s crust, boils when it meets magma, and explodes through chimney-like structures called “black smokers” in hydrothermal sea vent communities.

Hydrothermal vent - Wikipedia

A hydrothermal vent is a fissure on the seafloor from which geothermally heated water issues. Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart at spreading centers, ocean basins, and hotspots. Hydrothermal deposits are rocks and mineral ore deposits formed by the action of hydrothermal vents.
