Abstract
To develop an eco-friendly titanium (Ti) production process, the calciothermic reduction of titanium dioxide (TiO₂) was investigated. The mechanism involved in the reduction of TiO₂ using calcium (Ca) was examined. The influence of a molten salt, calcium chloride (CaCl₂), on the calciothermic reduction was investigated by conducting experiments at 1123..... More

Abstract
Lithium is a representative rare metal and ranks 32nd in abundance among elements in the earth’s crust. Lithium is used in a variety of applications, including the production of organolithium compounds, as an alloying addition to aluminum and magnesium, and as the anode in rechargeable lithium ion batteries especially for.....

Abstract
Blast furnace sludge, which comes from the iron making process, contains many valuable materials including iron, carbon, and zinc, etc. Because a cohesive agent is added during filtration, fine sludge particles are agglomerated together. Therefore, This makes it necessary to disperse the sludge in solution before separating or recovering valuable..... More

Abstract
This study on the chlorination of ilmenite ore was carried out using chlorine gas and coke as the chlorinating and reduction agents in a static bed reactor for the selective removal of iron. The effect of the amount of coke, the partial pressure of the chlorine gas and the reaction..... More

Abstract
A model based on Irwin's approach to elastic-plastic deformation was applied to predict the tensile ductility of a sintered iron. The evaluation of this model using experimental results for porous sintered iron showed that tensile ductility depends not only on the pore volume fraction, but also the pore size and..... More

Abstract
In this study, the effect of potassium persulfate on current efficiency for gold plating was investigated using electrochemical techniques. The current efficiency in the low-current-density range greatly decreased when potassium persulfate was added to the gold plating solution. However, the current efficiency in the high-current-density range did not change with..... More
