- China Northern Rare Earth receives a utility patent for advanced rare earth ore leaching technology with a step-like tank structure.
- The patented device prevents slurry short-circuiting and increases equipment utilization rate with a strategic overflow system.
- The company aims to enhance global competitiveness through strategic intellectual property development in the rare earth sector.
China Northern Rare Earth (opens in a new tab) recently received a utility patent from the China National Intellectual Property Administration (opens in a new tab) for its innovative "Continuous Leaching Device for Rare Earth Roasted Ore." The new design addresses efficiency and reliability challenges in traditional leaching systems, which often suffer from slurry short-circuiting, leading to reduced leaching time and low equipment utilization.
The patented device introduces a step-like structure for leaching tanks, with progressively lower foundational elevations, improving the equipment's utilization rate. Additionally, an overflow system with sidewall overflow pipes ensures that slurry must flow through designated pathways, preventing short-circuiting and achieving more efficient leaching. This design requires only a modest increase in concrete usage, delivering cost savings of approximately 300,000 RMB.
In recent years, China Northern Rare Earth has focused on building a robust portfolio of high-value patents, fostering innovation from laboratory research to industrial-scale applications. By strengthening intellectual property strategies, the company aims to enhance its global competitiveness in the rare earth sector.
Moving forward, it plans to further optimize IP management, drive cutting-edge R&D, and accelerate the transformation of technological achievements, fueling its vision to become a world-class leader in the rare earth industry, according to the company’s press entry (opens in a new tab).
