Upgradation of bauxite by molecular hydrogen and hydrogen plasmaB.R.Parhi1,S.K.Sahoo1,S.C.Mishra11. Department of Metallurgical and Materials Engineering, National Institute of Technology摘 要:An approach was developed to upgrade the bauxite ore by molecular hydrogen and hydrogen plasma. A gibbsite-type bauxite sample was obtained from National Aluminium......
Reduction and melting behavior of carbon composite lateritic bauxite pelletsYing-yi Zhang1,2,Jie Zhao1,Yuan-hong Qi1,Xiang-li Cheng1,Zong-shu Zou21. State Key Laboratory of Advance Steel Processes... bauxite was studied at high temperature to recover Fe and beneficiate Al2O3 slag. The results show that a metallization rate of 97.9% and a nugget recovery rate of 85.1% can be achieved when......
ON THE UTILIZATION OF BAUXITE OF POOR QUALITY余其俊,童大懋,易帆,周宗辉摘 要:<正> One kind of energy saving and high early strengthcement can be produced by using bauxite of poorquality which is refuse before. Through a series ofexperiments proper chemical compositions of the cementare obtained, and the cement clinker is sintered at alow temperature (1250......
University, Changsha 410083,China) Abstract: Using the two kinds of ore from Henan province, the oxidation roasting process of the desulfuration from the diasporic high sulfur bauxite was studied... of desilication from diasporic bauxite by roasting alkali leaching process[J].

Preliminary Study on Enrichment Law of Associated Rare Earth Elements in High-Sulfur Bauxite from Guizhou刘志红,岳紫龙,张覃,卯松,成奖国,聂光华,牛芳银摘 要:The Inductively Coupled Plasma-mass Spectrometer (ICP-MS) was used for measuring the content of rare earth elements in Guizhou high-sulfur and high-silicon bauxite ore and products of mineral processing. The results show......
Pre-desilication and digestion of gibbsitic bauxite with lime in sodium aluminate liquorXiao-lin Pan, Hai-yan Yu, Kai-wei Dong, Gan-feng Tu, and Shi-wen Bi School of Materials and Metallurgy, Northeastern University, Shenyang 110004, China摘 要:The effect of lime on the pre-desilication and digestion of gibbsitic bauxite in synthetic sodium aluminate......
Semi-industrial experimental study on bauxite separation using a cell?column integration processNing-ning Zhang1,2,Chang-chun Zhou1,2,Long-fei Cong1,2,Wen-long Cao1,2,You Zhou1,21. School of Chemical... for the separation of bauxite and its feasibility was analyzed on a theoretical basis. The properties of low-grade bauxite ore from Henan Province, China were analyzed. Parameters such as reagent dosage, scraping......
performance of bauxite with different iron contents were investigated systematically. The results indicate that such magnetic treatment can profoundly change the microstructure and digestion performance of bauxite. For the two samples carrying different iron contents, phase transformation of the aluminum oxide phase proceeds faster in the high iron bauxite than the low one. The optimal pretreatment......
