LONGi Debuts at the 2026 Red Mud Forum

On June 25, the much-anticipated 2026 National Forum on Technological Innovation and Development of Comprehensive Utilization of Red Mud grandly kicked off in Zibo, Shandong Province.

As a leading enterprise in the field of red mud separation equipment, Longi made a powerful presence at this forum as a key player in the resource utilization of red mud, showcasing its self-developed High-Temperature Red Mud Iron Extraction Process, innovatively tailored to the unique properties of red mud.

01 Tech Breakthrough: Original High-Temp Magnetic Separation Solves Industry Pain Points

At the exhibition site, Longi fully demonstrated the core advantages of this process in tackling tough challenges in red mud separation. Its self-developed high-temperature magnetic separation equipment stood out as the highlight of the event thanks to solid technical strengths and proven on-site application results, drawing extensive attention and heated discussions among all participating guests.

To address the separation difficulties caused by red mud’s properties including fine particle size, high viscosity, high temperature and high pH value, Shenyang Longji has put forward forward-looking and robust technical solutions:

Targeting core industry pain points, the company innovatively adopts vertical ring high-intensity magnetic separators to conduct direct high-temperature magnetic separation of red mud slurry, completely eliminating the long-standing industry problem of material adhesion and agglomeration under normal temperature conditions.

Precise Mineral Capture: Targeted upgrades to high-gradient high-intensity magnetic separation equipment have greatly improved the recovery rate of weakly magnetic iron minerals, enabling full extraction of iron resources from this industrial red residue.

02 Process Advantages: Core Tech Tackles Extreme Operating Conditions

Against the backdrop of cost reduction, efficiency improvement and green transformation, Longi’s tangible innovative achievements drew high attention from on-site alumina manufacturers:

High Recovery Rate

Relying on core technical barriers including high temperature resistance and corrosion resistance, the equipment drastically boosts the recovery rate of fine particles and delivers superior comprehensive recovery efficiency.

High Grade

It stably produces qualified iron products with total iron (TFe) content above 60%.

Intelligent & High-Efficiency

Equipped with real-time data collection and analysis functions, the system can independently judge operating conditions and trigger automatic alarms, delivering full intelligent performance.

Solving the bottleneck of red mud treatment is an essential task for the alumina industry to achieve zero-waste production. As a long-term dedicated player in this sector, Longi’s iron extraction solutions for red mud have been continuously refined and optimized through years of practical application. Bearing the responsibility of a pioneer, Longi will keep advancing technological iteration, and turn this global challenge into a powerful driving force for green development.
