Q. sintering of iron ore 1. INTRODUCTION :- 40 to 50% iron ore becomes under size which may create pollution in the plant of the mine site. For the utilization of the variable ore, it is necessary to agglomerate the fines into the required size for charging in the blast furnace. Agglomeration is the size incensement process of the fines ore.

Sintering - Wikipedia

Sintering 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 a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms in the materials diffuse across the boundaries of the ...

Sinter plant - Wikipedia

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the stone ...
