CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING

iron oxides are the major mineral phases for siliceous sinter, the ferrites, magnetite and mixed calcium iron silicates are the major mineral phases for fluxed sinter . Sintering is a fast process and it is unlikely that equilibrium will be reached during sintering. The reaction mechanism proposed for self fluxing sinter is summarized below :

Sintering

Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction. Sintering happens naturally in mineral deposits or as part of a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms in the materials diffuse across the boundaries of the particles, fusing the particles together and creating one solid piece. Because the sintering temperature

Ironsand

Ironsand is found worldwide. Although the iron mineral composition of the ironsand is mostly magnetite, the sand is usually mixed with other types of sand that washes downriver or ashore from mountainous or underwater deposits. The exact composition of the sand mixture may vary drastically even in the same geographic region. In some areas the sand may contain mostly quartz, while in others the sand may be made primarily from volcanic rock such as basalt, depending on the types of minerals along the water's p
