Abstract: To address the growing imbalance between the supply and demand of critical metals on land and the strategic need for deep-sea mineral resource development, seafloor massive sulfides (SMS), enriched in copper, zinc, gold, and silver, have attracted increasing attention. However, the complex topography of deep-sea hydrothermal regions and the uniqueness of benthic ecosystems pose significant challenges to achieving environmentally responsible and low-disturbance mining. This paper systematically reviews the development history and current status of SMS mining technologies, and analyzes the technological evolution from early systems, including drag bucket, bucket-chain, and shuttle-based mining methods, to modern pipe-lift mining systems, while examining the characteristics and applications of both tracked and vertical mining systems. Despite continued technological progress, the commercialization of SMS mining remains constrained by several bottlenecks, including limited operational stability of seafloor mining vehicles, risks of clogging and abrasion within the ore lifting system, and potential ecological risks associated with sediment plume dispersion during mining operations. In response, this paper identifies an emerging development trend toward building an intelligent, low-disturbance, and fully integrated SMS mining system. The core elements of this future system include improving the precision and low-disturbance performance of seabed mining equipment, enhancing the reliability of ore transport systems, strengthening the adaptability of surface multifunctional support platforms, and establishing an integrated environmental management framework based on monitoring-prediction-regulation. Finally, from the perspectives of technological innovation, system optimization, and international cooperation, the paper proposes several recommendations, such as advancing engineering validation of key equipment and components, developing a coordinated mining-lifting-monitoring system architecture, and strengthening technical and data contributions to the formulation of international seabed management regulations. These efforts aim to support the engineering deployment and commercialization of green SMS mining technologies in China.
