the composite of nanomaterial and micronmaterial by adding micronmaterial during production of nanomaterial through sol-gel method, also introduces the technique and experiment''s process preparation...Preparation of Nano/Micron Composite Materials by Process Method GAN Ai-feng1,YAO Jun-min1,WEI Qi1,HU Chuan-xin1,Yuan1,JI1 (1.Department of Materials Sciences & Engineering,Beijing University......
and increases the activation energy of dissolution, the diffusion process of which is the rate-controlling step. Key words: gibbsitic bauxite; dissolution; kinetics; ferrite; Bayer process 1 Introduction... during the Bayer process. The selection of Bayer process depends on the kinds of bauxite. Low temperature Bayer process only can deal with gibbsitic bauxite [2-4]. Goethite and hematite are commonly......
diasporic bauxite with low and medium grades by lime Bayer process CHEN Bin, XIAO Li, TANG Xianmin (College of Metallurgical Engineering, Hunan University of Technology, Zhuzhou 412011, China) Abstract: The digestion experiments of lime Bayer process using diasporic bauxite from Guizhou Province with low and medium grades (alumina-silica ratio is 5.48) were completed. The influences of lime amount......
