The deep-sea ecosystem is relatively fragile, and large-scale commercial development may have an adverse impact on the marine environment. During the transportation of polymetallic nodules from the seabed to the sea surface, the friction and collision between the metal nodules and the tube wall and between the nodules cause the nodules to break and powder. Nodules with larger particle sizes enter the ore cabin, while nodule powders with small particle sizes (less than 0.1 mm) will be discharged into the sea with the tail water.
