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......

. School of Mining Engineering,University of Tehran摘 要:Jajarm’s bauxite deposits are mainly diasporic,and they have a low mass ratio of Al2O3/SiO2. It is necessary to increase the run-of-mine mass ratio before feeding the material to the Bayer process. Chemical analysis indicated that the low-grade bauxite sample from Jajarm contained 43.9wt% Al2O3......
