Hydraulic Collector for Polymetallic Nodules from the Deepsea


Deep sea mining is one of the new fields of industry that can aid in the supply of critical raw materials. Vast amounts of polymetallic nodules are found on the floor of the Clarion Clipperton Zone in the Pacific Ocean at typical water depths of 3 to 6 kilometers, containing appreciable amounts of cobalt, nickel and copper. To date, subsea harvesting equipment (collectors) is known to generate large plumes of suspended particles which will have serious impacts on seabed life in the areas surrounding the mine sites and potentially for some kilometers distant to the mine sites.
