  "abstract": "Deep-sea mineral resource exploitation constitutes a crucial component of marine development. Traditional hydraulic and pneumatic lifting technologies are confronted with prominent challenges, including plume pollution risks induced by tailwater discharge and economic limitations stemming from the restricted volumetric concentration of ore slurry. To address these bottlenecks, this study proposes a “closed-cycle lifting operation mode” oriented toward green and high-efficiency development requirements. The core influencing factors of deep-sea mining, such as environmental friendliness, economic efficiency and operational reliability, are systematically reviewed. Subsequently, a closed-cycle system scheme centered on dual-channel risers is proposed. Additionally, key technical challenges are analyzed in depth, covering the material and structural design of dual-channel risers, multiphase flow stability, system integrated control, as well as the pressure resistance and sealing performance of semi-enclosed relay stations. The research results demonstrate that the proposed mode establishes a closed circulation loop to realize the recycling of the lifting medium, thereby eliminating plume pollution caused by direct tailwater discharge. Meanwhile, the adoption of micro-foam medium effectively reduces the average density and flow resistance of ore slurry in pipelines, leading to a significant reduction in unit energy consumption for ore transportation. The closed-cycle lifting operation mode proposed in this paper can effectively meet both environmental and economic requirements of deep-sea mining, and represents a promising direction for the green and high-efficiency exploitation of deep-sea mineral resources in the future.",
