In this paper, published studies on the bonding phase of calcium ferrite are reviewed. As main high-basicity sinter, has advantages high strength, good reducibility and easy formation liquid phase. particular, we emphasize process phases, especially Silico-Ferrite Calcium Aluminum(‘SFCA’), influence common gangue components (Al2O3, SiO2, MgO) its formation. Based critical analysis current data,...

The research presented in this article assessed geochemical factors relating to dust produced during primary lead smelting. Bulk dust samples and size-selective airborne dust samples were collected from four areas of a primary lead smelter and analyzed by X-ray diffraction and sequential chemical extraction. X-ray diffraction showed that the smelter dusts were composed primarily of sulfides, ox...

The target basicity of iron ore sinter is set by blast furnace slag composition requirements, and therefore varies with the proportion acid burden such as lump pellets. Increasing will increase basicity. mineralogy produced a range between 1.0 3.0 was analysed using optical point counting under reflected light microscopy. Sinter from BlueScope Steel’s industrial strand over 30-year period, duri...

Iron ore granulation is an indispensable process in the production of sinter that can influence and regulate yield, efficiency quality. Although a great deal research has been done on over past decades, we still need to think about current future development this process, as essential raw material for ironmaking blast furnace today. This paper begins with review particle agglomeration theory si...
