Deep Sea Mining

Deep sea mining is a relatively new mineral retrieval process that takes place on the ocean floor.Ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at about 1,400-3,700 m below the ocean’s surface.The vents create sulfide deposits, which contain valuable metals such as silver, gold, copper, manganese, cobalt, and zinc.

Among the impacts of deep sea mining, sediment plumes could have the greatest impact. Plumes are caused when the tailings from mining (usually fine particles) are dumped back into the ocean, creating a cloud of particles floating in the water. Two types of plumes occur: near bottom plumes and surface plumes.[1] Near bottom plumes occur when the tailings are pumped back down to the mining site.
