Substance flow analysis of neodymium based on the generalized entropy in China
By a News Reporter-Staff News Editor at China Weekly News -- Current study results on Conservation Research have been published. According to news reporting out of Beijing, People’s Republic of China, by VerticalNews editors, research stated, “Rare earth plays an important role in fields of aerospace, electronic products, catalyst, agriculture and others. China is the largest producer and consumer of rare earth materials in the world.”
Funders for this research include National Key Research and Development Plan, The National Natural Science Fund for Innovative Research Groups, Beijing Municipal Science & Technology Commission Project, National Key Research and Development Program.
Our news journalists obtained a quote from the research from the Beijing University of Technology, “Neodymium is widely used in rare earth industry. Substance flow analysis (SFA) is an established method to analyze the structure and characterization of substance flows. This paper provided SFA and generalized entropy analysis for neodymium in China in 2002 and 2011. System boundary included exploitation, concentration, smelting, manufacture, use and disposal. Neodymium flow amounts and generalized entropy value were calculated, respectively. Mining utilization efficiency, smelting ratio, export rate were comparatively analyzed in 2002 and 2011. The results demonstrated that the utilization efficiency of neodymium in the rare earth concentrates production stage increased more than 69%, while the utilization efficiency of neodymium in the manufacture stage increased more than 28% in 2011 compared to 2002. The generalized entropy results indicated that congregated degree of neodymium was larger in 2011 compared to 2002 after concentrate production stage and manufacture stage, the congregated degree increased 45.5% and 12.5%, respectively.”
According to the news editors, the research concluded: “Based on the results, some advices were proposed, which provided available reference information for resource conservation and environmental friendly development of the Chinese rare earth industry.”
