Longi Debuts at the 2025 Mining Science and Technology Conference
The 15th Mining Science and Technology Conference (2025) convened with great fanfare in Wuhan. Serving as a critical platform for technical collaboration within China’s mining industry, the conference assembled leading experts and enterprise delegates to share insights on emerging advancements and pioneering applications in mining technology.
Longi Magnet, Longi Optoelectronics, and Longi Intelligent jointly participated in the conference, systematically showcasing their technological achievements and solutions in the field of intelligent and green mining equipment.
Three chief engineers delivered insightful keynote speeches at the conference forum. Focusing on core technologies including high-efficiency magnetic separation, intelligent photoelectric sorting, and unmanned online detection respectively, they elaborated in detail on the company’s innovative breakthroughs and successful application cases in intelligent and green mining equipment. Their presentations sparked profound reflections and lively discussions among attendees about the future vision of smart mines.
---Zheng DeLiang, chief engineer in Longi Magnet mining department
Zheng Deliang’s speech on High-Efficiency Magnetic Separation outlined solutions for challenging ores, showcasing Longi’s LCTC/LCGJ/LJC Series. These smart, structurally optimized systems cut costs and boost recovery in iron ore processing.
Longi’s newly launched solutions include:
The LCTC Series Wet Pre-Concentration Magnetic Separator for ultra-fine crushed ores;
The LCGJ Series 3mm Balanced Dry Magnetic Separator;
High-efficiency magnetic separators for ultra-fine grinding processes;
The LJC Series Magnetic Suspension Concentrator, featuring advanced electromagnetic separation technology for micro-fine particles.
---Shi YuLin, chief engineer in Longi Optoelectronics, delivered an insightful presentation titled "Research and Application of Photoelectric Sorting Equipment."
He highlighted that as ore resources become increasingly complex and lower-grade, conventional sorting processes face mounting challenges. Photoelectric sorting technology, with its high precision and efficiency, has emerged as a powerful solution to these issues.
Longi Optoelectronics’ LPNC and LPPC sorting systems integrate advanced X-ray transmission (XRT) and X-ray fluorescence (XRF) technologies. These innovations enable rapid and accurate identification of valuable minerals versus gangue, while high-speed actuators ensure precise pre-sorting and waste rejection.
---Wu WeiChen, chief engineer in Longi Intelligent.
Wu Weichen shared insights on the theme "The Unmanned Laboratory Concept: Technological Innovation in Online Slurry Grade Detection."
He pointed out that traditional slurry analysis methods suffer from complex procedures, high labor intensity, and delayed data feedback, which severely hinder mining efficiency and accuracy. In response, Longi Intelligent has developed an X-ray fluorescence (XRF) online multi-element slurry analyzer, enabling real-time, automated analysis of multiple element grades in slurry.
The device employs an industry-first solid-state reference non-contact detection technology. By instantly converting slurry into solid reference samples for non-contact measurement, it significantly enhances detection precision and reliability. This breakthrough not only improves production stability and reduces labor costs but also provides critical technical support for the transition toward intelligent and unmanned mining operations.
The event featured a collaborative exhibition by Longi Magnet, Longi Optoelectronics, and Longi Intelligent, demonstrating their technological leadership in intelligent mineral processing with a robust lineup of innovative solutions.
