AI Technical Summary
The existing deep-sea manganese nodules need to be transported to land for smelting after collection, resulting in high energy consumption and environmental pollution. Furthermore, the deep-sea mining process has failed to achieve integrated processing of mining and smelting.
Design a deep-sea mining and smelting system, including an offshore floating platform, a lifting riser, a mining vehicle, and a power supply system, to realize an integrated process of mining and smelting manganese nodules. The system utilizes smelting equipment on the offshore floating platform to smelt the collected manganese nodules in real time, and uses ammonia leaching residue to treat refining wastewater, thereby reducing pollution.
This technology enables the immediate smelting of manganese nodules, saving time, improving production efficiency, and reducing pollution and impact on the marine environment through full utilization of resources.
