Abstract | Deep sea Polymetallic nodules (PMN) are rich with metals that serves as a potential resource for commercial development. The depositional deep-sea environment of PMN is unique due to which usage of specialized deep sea mining technology and adequate equipmentâ¿¿s are essential for nodule extractions. The technology is recognized as key components for nodules mining commercialization. However, there is an increasing need to upgrade the mining technology in order to support commercialization of PMN programmed. Integrated continuous mining concept involving surface vessel, lifting pipes, buffer, and crawler are considered to be most prospective for commercial production of PMN. Reliable and meticulous operation to the whole mining system to mitigate the impact is of particular importance. In view of environmental concern and reduction of technology risk, the results from research into PMN key mining technology are analyzed. The smooth performance of crawler, efficiency of nodule pick- up conveyor belt, presence of crusher, transfer of nodules through flexible riser pipe, unwanted slurry tailing discharge are studied to compare different PMN mining technology and evaluate the technical feasibility, and the environmental impact assessment. The key interests to address the environmental concern are focused on the sediment disturbances, Nodules pick-up style, and whether the nodules are to be crush or not, filtration for the tailing discharge needed or not. Technology comparison is also made so as to try to discern the most ideal variant if commercial mining ever takes place now and ever. This may provide a reference for the research and development of efficient technology for deep sea PMN mining. |
