deep sea mining relatively new mineral retrieval process takes place on ocean floor. ocean mining sites around large areas of polymetallic nodules or active , extinct hydrothermal vents @ 1,400 – 3,700 meters below ocean s surface. vents create sulfide deposits, contain precious metals such silver, gold, copper, manganese, cobalt, , zinc. deposits mined using either hydraulic pumps or bucket systems take ore surface processed. mining operations, deep sea mining raises questions environmental damages surrounding areas because deep sea mining relatively new field, complete consequences of full-scale mining operations unknown. however, experts removal of parts of sea floor result in disturbances benthic layer, increased toxicity of water column, , sediment plumes tailings. removing parts of sea floor disturbs habitat of benthic organisms, possibly, depending on type of mining , location, causing permanent disturbances. aside direct impact of mining area, leakage, spills, , corrosion alter...
