en.Wedoany.com Reported - Recently, three patents independently developed by the China Copper Industry Mining Research Institute—"A Position Monitoring Device and Dredging Method for Blocked Backfill Pipelines," "A Comprehensive Utilization and Recovery Process for Polymetallic Ores," and "A Method for Comprehensive Recovery and Utilization of Lead-Tin-Silver Oxide Ores"—have been granted invention patent authorization by the National Intellectual Property Administration.

Since its official establishment in July 2025, the China Copper Industry Mining Research Institute has aimed to build a first-class mining research institute in the non-ferrous metals industry. Focusing on the needs of enterprises under Chinalco Group and China Copper Industry, it adheres to independent innovation, relies on project implementation and on-site factory services, and continuously intensifies the tackling of key core technologies. Public information shows that the institute has assembled a professional R&D team of over 80 people, led by industry senior experts, doctors, and senior engineers, providing solid talent support for technological innovation.

Since its inception, the institute has achieved fruitful results. To date, it has cumulatively obtained 10 authorized invention patents. The three patents recently granted authorization represent another breakthrough in its mining technology field. Among them, "A Position Monitoring Device and Dredging Method for Blocked Backfill Pipelines" can accurately locate blockages and effectively dredge them, improving mining operation efficiency. In practical applications, dealing with backfill pipeline blockages previously took an average of 4 hours and required manual inspection, posing certain safety risks. After adopting this patented technology, positioning time is reduced to within 10 minutes, and dredging time does not exceed 1 hour, significantly lowering labor costs and safety risks. "A Comprehensive Utilization and Recovery Process for Polymetallic Ores" can improve the recovery and utilization rate of polymetallic ores, reducing resource waste. Taking a specific polymetallic ore as an example, the traditional process had a recovery rate for associated metals of only 60%. After adopting the new process, the recovery rate increased to 85%, generating tens of millions of yuan in additional economic benefits for the enterprise annually. "A Method for Comprehensive Recovery and Utilization of Lead-Tin-Silver Oxide Ores" targets specific ores, achieving efficient recovery and utilization, raising the comprehensive utilization rate of such ores from the original 50% to 75%.

Currently, these patented technologies have entered the stage of achievement transformation, with some technologies already undergoing pilot applications in relevant mining enterprises. According to pilot feedback, the related technologies have increased mining production efficiency by 15% and improved comprehensive resource utilization by 10%. Taking a mining enterprise with an annual ore processing capacity of 1 million tons as an example, after adopting the new patented technologies, it can recover approximately 2,000 tons more of various metals annually while reducing waste emissions by about 300,000 tons. This not only enhances the enterprise's economic benefits but also plays a positive role in environmental protection.

In the next step, the China Copper Industry Mining Research Institute will continue to focus on the forefront of mining technology and persistently build an innovative technical support and R&D system. It plans to invest 50 million yuan in new technology R&D over the next three years to further expand its patent achievement reserves. At the same time, it will strengthen cooperation and exchanges with domestic and international research institutions and universities, introducing advanced technologies and concepts to enhance its own innovation capability and R&D level. It aims to empower the transformation and application of scientific and technological achievements through technological innovation, promote the green, low-carbon, safe, and efficient development of mining enterprises, and help China's non-ferrous metals industry occupy a more favorable position in global competition.
