What Is Iron Ore Sintering? (with pictures)
Other iron ore sintering processes use machines that take crushed iron ore and mix it with water and other substances, known as fluxes, prior to igniting the mixture. Electricity is conducted through the mixture, and its surface is ignited to help form an agglomerate. Dust from the iron ore, as well as iron particles that do not meet size requirements, are recirculated through the machine with ...

The main purpose of iron ore sintering is to produce ironbearing agglomeration as a burden for blast furnace. The feed material melts partially and agglomerates at a high temperature in the sintering bed, then the semimolten mate rial solidifies and crystallizes into various mineral phases in subsequent cooling period. 1) Figure 1 shows a conceptual version of the iron ore sintering ...

PROCESS BRIEF
During the sintering process, iron ore fine particles agglomerate into a porous compact heterogeneous lumpy mass called SINTER by incipient fusion caused by the heat produced during the combustion of the solid fuel within the moving bed of loosely particles. The coke at the top of the blend is ignited by gas burners, that can be fueled by coke oven gas, blast furnace gas, or natural gas. As ...
