Using waste plastics and other organic waste as reducing agents, the technology generates reducing gas through low-temperature pyrolysis to achieve in-situ reduction of tailings within a single integrated system. This approach integrates solid waste treatment, tailings enrichment, and energy circulation, challenging the traditional assumption that high temperatures are required for efficient reduction. The production line features three core advantages: (1) Low-temperature continuous reduction below 700°C (industrial range 550-600°C), with a reduction rate exceeding 50% - significantly lower than traditional smelting; (2) Highly efficient energy utilization with >93% waste heat recovery, 36%+ reduction in energy consumption, and ~40% lower CO2 emissions; (3) Intelligent safe operation via material-temperature coordinated regulation, dynamic sealing, and smart control, enabling large-capacity continuous stable operation.
Leveraging decades of R&D and engineering experience, Niutech partners with global mineral and solid waste customers to deliver cost-competitive, delivery-certain environmental equipment and green solutions for strategic mineral recovery and industry low-carbon transformation.
