:1672-7207(2010)03-0852-07 Desulfuration of high sulfur bauxite by oxidation roasting HU Xiao-lian, CHEN Wen-mi, XIE Qiao-ling (School of Metallurgical Science and Engineering, Central South 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......
Processing and Bioengineering,Central South University摘 要:Consolidation in calcines is a common problem in the oxygen-enriched air roasting of refractory gold.... Oxidation of the pyrite and decomposition of the dolomite and muscovite mainly occurred at the initial stage of oxygen-enriched air roasting. Calcium was confirmed to be essential to the consolidation......

School of Materials and Metallurgy... of roasting high-titanium slag with concentrated sulfuric acid was proposed to prepare titanium dioxide, and the roasting kinetics of titania was studied on the basis of roasting process. The effects......
and waste discharge. A method of microwave roasting was adopted for dechlorination of CuCl residue. A 1.5 kW microwave roasting equipment with dust collection and tail gas adsorption systems was set up... rate is as high as 90%, while that with conventional heating is only 60%-80%. The phase change of the roasting process investigated with X-ray diffraction verifies that CuCl in CuCl residue is removed......
