There have been several attempts to determine the reducibility of iron ore quantitatively in order to have a measure for blast furnace operation: (i) estimation through blast furnace operation by the JIS reduction degree; (ii) determination of the reaction rate constant of reduction and comparison ...
The cohesive zone is a region of low permeability in a blast furnace. This study shows the impact of the chemical composition of pellets on the metallurgical processes occurring in this region during the iron ore reduction process. Sixteen pellets containing varying contents of MgO, CaO, and SiO...
A study has been carried out of the sintering behavior of the complex domestic iron ore concentrate that is used by the Shanghai Meishan Metallurgical Corp. in China. The ore contains significant sidetrite, magnetite and hematite, and studies conducted showed that the sidetrite has a very signif...
The chemical formula of Iron III oxide is Fe2O3. It is obtained from a mineral ore called hematite. It is mined and then processed to obtain iron oxide for extracting the metal. Iron is also called Ferrum in Latin. The valency of this metal is 2 and 3. When it combines with valency...
Ilmenite is natural mineral ore made up with titanium and iron mineral; including small portion of magnesium and manganese. To the best of our knowledge, photo-degradation of Reactive Black 5 dye (RB 5) using ilmenite under solar irradiation is still lacking. In the present study, the physicoc...
However, the use of iron ore tailings was also studied in the red clay ceramics industry, in which physical, chemical, mineralogical, and morphological properties were characterized [27]. There are hundreds of brick kilns existing in the Peshawar region, producing good quality bricks at a ...
This kind of force is difficult to calculate. The packing behavior of wet particles is different from that of dry particles, as seen from work on the packing of iron ore fines or coal particles (Yu et al., 1995). Results showed that there were many forms of water between the particles ...
Implication of process mineralogy for beneficiation of low grade iron ore resources containing high alumina from eastern part of India The microscopy, petrography and ore mineralogical characterization will be investigated of various mineral beneficiated ores. Investigations suggest that iron ore... V Kuma...
we report the synthesis of single system three-dimensional (3D) open porous structure of MgCr-LDH nanoparticles in a substrate-free path by using one-step formamide assisted hydrothermal reaction followed by visible light irradiation for significant photoelectrochemical (PEC) properties that manifest towar...
The KKI process is a new process combining vacuum residue (VR) thermal cracking and direct reduction of iron ore, using coke deposited on it as the reducing agent. A pilot plant with VR treating capacity of 30B/D was constructed in October 1982 and was operated for one year. Data on prod...
