CSIR-Central Road Research Institute, New Delhi 110025, India Received 31 October 2012; accepted 6 April 2013 Abstract: The characterization and H2SO4 leaching behavior of a Nigerian ilmenite......
for vanadium-bearing titanomagnetite,ilmenite concentrate,and high titania slag.The possibility of selective carbothermal reduction was discussed in detail from the viewpoint of thermodynamics,and also......
图分类号:TD 91 文献标识码:A Autogenous-carrier flotation of fine ilmenite ZHU Yang-ge, ZHANG Guo-fan, FENG Qi-ming, LU Yi-ping, OU Le-ming (School of Resources Processing and Bioengineering, Central South University, Changsha 410083, China) Abstract: The autogenous-carrier effect in fine ilmenite (0?20 μm) flotation was investigated. The results show......
titanomagnetite concentrate(VTC) by adding CaCO3 was investigated. Thermodynamic analysis was employed to show the feasibility of calcium titanate formation by the reaction of ilmenite and Ca CO3 in a reductive atmosphere, where ilmenite is more easily reduced by CO or carbon in the presence of CaCO3. The effects of CaCO3 dosage and reduction temperature on the phase transformation and metallization degree were......
of symbiotic complex ore which comprises ilmenite, magnetite, hercynite and magnesio-hercynite spinel minerals. The ore collected from eastern India was characterized by XRD, WDXRF, SEM and spectroscopy... the samples for different periods of time at different temperatures from 873 K to 1473 K. It was observed that ilmenite phase transformed to hematite and titanium dioxide at lower temperature, whereas......
. The results show that the products of HPGR are finer than those of conventional jaw crusher. Parallel separation of titanium magnetite(Fe) and ilmenite(Ti) can be realized through direct separation... recovery of ilmenite increases by 2.66%. The mineral degree of liberation in the primary grinding from this two comminuting processes become obviously different. Iron minerals of HPGR product......
