| 1 | Effect of coal levels during direct reduction roasting of high phosphorus oolitic hematite ore in a tunnel kiln显示文摘The effect of coal levels on phosphorus removal from a high phosphorus oolitic hematite ore after direct reduction roasting have been investigated. Raw ore, coal, and a dephosphorization agent were mixed and the mixture was then roasted in a tunnel kiln. The roasted products were treated by two stages of grinding followed by magnetic separation. XRD and SEM-EDS examination of the products was used to analyze differences in the roasted products. The results show that coal is one of the most important factors affecting the direct reduction roasting process. When the inner coal levels increased from 0% to 15% the iron grade decreased linearly from 94.94% to 88.81% and the iron recovery increased from 55.94% to 92.94%. At the same time the phosphorus content increased from 0.045% to 0.231%. Increasing the inner coal levels also caused more hematite to be reduced to metallic iron but the oolitic structure of the roasted product was preserved in the presence of high coal loading. The phase of the phosphorus in raw ore was not changed after direct reduction roasting. The effect of coal on the phosphorus content in the H-concentrate arises from changes in the difficulty of mechanically liberating the metallic iron from the phosphorus bearing minerals. | Li Yongli Sun Tichang Zou Anhua Xu Chengyan | 2012 | International Journal of Mining Science and Technology2012，22，3： | 22 |

| 15 | Effect of atmosphere on the synthesis of potassium titanate显示文摘Potassium titanate (K4Ti3O8) was synthesized by the reaction between ilmenite and concentrated KOH solution in the atmosphere of nitrogen,still air,and oxygen,respectively.The obtained samples were systematically investigated by X-ray diffraction (XRD),inductively coupled plasma optical emission spectrometer (ICP-OES),and scanning electron microscopy (SEM).XRD results indicate that K4Ti3O8 have been synthesized in different atmospheres.The oxidizing atmosphere could enhance the conversion rate of Ti from ilmenite to K4Ti3O8,and Fe(II) is easily oxidized to trivalent iron Fe(III) during the reaction.Furthermore,SEM images show that the different atmospheres have significant effect on K4Ti3O8 crystal morphology and particle size.Well shaped K4Ti3O8 crystals are obtained in nonoxidizing atmosphere. | LI Jie WANG Yong WANG Lina SUN Tichang QI Tao ZHANG Yi | 2010 | Rare Metals2010，29，3： | 1 |

| 19 | Combined Effect of Arsenic and Cadmium on the Transformation of Ferrihydrite into Crystalline Products显示文摘Ferrihydrite, prepared in the presence of different amount of As and Cd in the solution, was used to study the combined effect of As and Cd coexisted in the same system on the transformation of ferrihydrite into crystalline products at pH & and pH 12. The data showed that there was apparent interaction between As and Cd in the transformation process. At pH 8, the transformation product was hematite with 1% As and different percent Cd (mole fraction, so as the follows), but the size of particles formed with different amount of Cd was different. At pH 12, the transformation products varied from sole hematite with 1% As and less than 2% Cd to a mixture of hematite and goethite with more than and equal to 2% Cd, and the percentage of goethite in the transformation products increased with the increasing level of Cd in the system. XRD (X-ray diffraction) and chemical analysis data showed that almost all As and part of Cd initially present in the system were retained in the crystalline products. The presence of As increased the amount of Cd retained in the structure of iron oxide. SEM (Scanning Electron Microscope) examination showed that the presence of As and Cd also altered the morphology of cry stalline products. | Tichang Sun C R Paige W J Snodgrass(Resources Engineering School.

| 20 | Petroleum coke as reductant in co-reduction of low-grade laterite ore and red mud to prepare ferronickel: Reductant and reduction effects显示文摘Petroleum coke is industrial solid wastes and its disposal and storage has been a great challenge to the environment. In this study, petroleum coke was utilized as a novel co-reduction reductant of low-grade laterite ore and red mud. A ferronickel product of 1.98wt% nickel and 87.98wt% iron was obtained with 20wt% petroleum coke, when the roasting temperature and time was 1250°C and 60 min, respectively. The corresponding recoveries of nickel and total iron were 99.54wt% and 95.59wt%, respectively. Scanning electron microscopy-energy dis- persive spectrometry (SEM-EDS) analysis showed metallic nickel and iron mainly existed in the form of ferronickel particles which distrib- uted uniformly at a size of approximately 30 μm with high purity. This study demonstrated that petroleum coke is a promising reductant in the co-reduction of laterite ore and red mud. Compared to other alternatives, petroleum coke is advantageous with reduced production cost and high applicability in anthracite-deficient areas. | Xiaoshuang Guo Zhengyao Li Jicai Han Dong Yang Tichang Sun | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，3： | 0 |
