China Symposium on Comprehensive Utilization of Rare Earth Resources Held in Shenzhen

Organized by the China Rare Earth Society's Selection and Selection Committee, the "China Rare Earth Resources Comprehensive Utilization Symposium" hosted by the Baotou Iron and Steel Group Mining Research Institute was successfully held in Shenzhen on October 23-26, 2009. A total of 55 leaders, experts and scholars from universities, research institutes and enterprises across the country attended the meeting. Wang Xinlin, secretary-general of the China Rare Earth Society, attended the meeting and delivered a speech at the opening ceremony. Cheng Jianzhong, director of the China Rare Earth Society's Selection and Selection Committee and president of Baotou Mining Research Institute, delivered an opening speech. The opening ceremony was attended by the China Rare Earth Society. Director Li Linsen presided over.

At the conference, nearly 50 papers were received, and 29 papers were selected and edited into a collection of papers. The papers cover a wide range of topics, including theoretical research papers and industrial development papers, which comprehensively reflect the comprehensive development and utilization of rare earth resources in China and rare earths. Deep processing of resources and technical status and development trends in areas related to environmental protection.

Representatives at the meeting had extensive exchanges. The conference report consisted of 13 articles: Yu Yongfu (Che Liping), Academician of the Chinese Academy of Engineering, reported that improving the quality of iron concentrate is an effective way to improve energy efficiency and reduce emissions of blast furnaces; Yang Dongming, Institute of Geology and Geophysics Research Institute: Study on chemical composition and crystallographic characteristics of Baiyun Ebo sillimanite; Lai Zhaotian and Yao Yuzhou, deputy general manager of Cangzhou Rare Earth Mining Co., Ltd. report: Weathering shell leaching using in-situ leaching process Type rare earth mine; Dong Xianhong, Sichuan Provincial Mineral Resources Reserve Evaluation Center: Analysis of metallogenic geological characteristics of rare earth deposits in mainland China, Dechang County, Sichuan; Director Yuan Changlin of Zhangzhou Nonferrous Metallurgy Research Institute: China Nanling leaching type rare earth leaching mining positive pressure Geological classification of the system and corresponding mining technology; Liu Jianyong, Baotou Steel, Obo Iron Mine, Liu Jianyong report: Study on the distribution law of refractory ore in the main ore of Baiyun Obo; Professor Qi Zhe from Guangdong Foshan Institute of Science and Technology Report: Electroless nickel-phosphorus/rare earth electrolysis Research on the improvement of water hydrogen production efficiency; research on rare earth and micro/nano functional materials in Nanchang University Professor Li Yongxiu reports: Using environmental protection standards to standardize the mining of ionic rare earth resources, and using functionalization requirements to improve the level of rare earth industry; Guizhou University Qiu Yueqin report: Distribution characteristics of rare earth minerals in Guizhou rare earth phosphate deposits; School of Mining, Guizhou University Pine Report: Study on the Determination of Total Rare Earth by Absorption Spectrophotometry; Lei Yugang, Mei Guangjun, School of Resources and Environmental Engineering, Wuhan University of Technology, Report: Recovering Rare Earth Y2O3 from Waste Phosphors; Zhang Yong Report of Baotou Steel Technology Center: Package Experimental study on recovery of rare earth from steel tailings; Zhang Zhonghan, professor of Guangzhou Nonferrous Metal Research Institute, reports on the new process of ore dressing in a scheelite in Northwest China.

The convening of the conference provided a platform for discussion and exchanges for the delegates. It will play a positive role in better implementing and implementing national policies in the future, scientifically developing comprehensive utilization of rare earth resources, and taking the road of sustainable development.

Foyer Light

Foyer Light is a type of lighting fixture used for decorating and illuminating entrance halls. It is typically installed on the ceiling and can be in the form of a chandelier, Semi-flush Mount, Wall Sconce, or ceiling fan light. The design of Foyer Light is often elaborate, and can be made of materials such as crystal, glass, metal, and can feature intricate patterns and decorations. It not only provides ample lighting, but also adds a touch of elegance and sophistication to the entrance hall.

The specific choice of Foyer Light also depends on the type of decoration effect suitable for various lamps and lanterns. However, it is generally necessary to meet the effect of the atmosphere and grade, and the current modern and simple Foyer Light is more popular, and the Lighting Fixture material is generally made of metal, stainless steel or acrylic. The installation method can be installed by ceiling or hanging wire, and the selection of lamps and lanterns should also be comprehensively considered from the later maintenance and management methods.
