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.

of lime assimilation. Lime is added to iron ore to improve the porosity and to obtain the correct sinter strength and permeability for use in the blast furnace. If the sintered ore does not have adequate strength, a large amount of fines will be produced during stockpiling and handling of ore before use in the blast furnace.

2C(1) Iron Ore

High-grade iron ore is crushed for sizing, producing both fine ore as well as lump ore. To beneficiate low-grade ore, it is first pulverized into finer particles called pulverized ore. Both fine and pulverized ores are then subjected to pre-treatments before they are charged into the BF; that is, the fine ore is processed into sintered.
