Title: Guanghua Nie and Manganese Ore Beneficiation
Introduction
Guanghua Nie is an inventor associated with Guizhou University in Guiyang, China. His patent work addresses the beneficiation of high-clay, low-grade manganese carbonate ore.
Latest Patents
The provided information lists one patent for Nie: “Beneficiation Method for High Clay Type Low-Grade Manganese Carbonate Ore.” The invention describes preparing polyepoxysuccinic acid (PESA) as a solution and adding it to the mill alongside the raw ore. The ore is ground until material finer than 0.075 mm accounts for 54–70% of the product. The ground material then undergoes one roughing and one scavenging stage using a high-gradient magnetic separator. The method aims to produce manganese concentrate with high grade and recovery. Nie is credited with 1 patent.
Career Highlights
Nie’s listed invention focuses on improving the processing of manganese carbonate ore that is both low-grade and high in clay content. The patent describes combining PESA-assisted grinding with staged magnetic separation.
Collaborations
The provided information names Yun Tang and Bo Wu as Nie’s coworkers. It does not specify their roles in the patent or the nature of their collaboration.
Conclusion
Guanghua Nie’s listed patent presents a beneficiation approach for challenging manganese ore, combining PESA-assisted grinding and high-gradient magnetic separation to seek improved concentrate grade and recovery.
