12%The iron ore fines with less than 10 mm size are usually fed to the sintering process, and only limited fraction (less than 20%) of − 150 micron size of iron ore fines are allowed in the sintering process. The finer sized iron ore may choke the sinter bed and hinder the uniform air suction through the bed.

Schematic of the experimental is presented in Fig. 1.A part of dry Noamundi iron ore fines was ground for 18 minutes to –45 μm (56% approx).The size distribution and Blaine fineness of it is shown in Table 5.The iron ore fines along with 0.5% bentonite binder were mixed with pyroxenite fines and other additives like coke fines, LDS etc. in varying quantity.
Iron ore sintering is a predominant process for fine iron ore and its concentrate to be applied in the blast furnace process. However, sintering produces a negative impact on the environment. One of the effective ways to reduce greenhouse gas emissions from iron ore sintering is to use CO2-neutral biomaterials for the fuel needs of this technology.
Iron ore size may affect the sintering characteristics. To avoid the effects of the particle size of IIO, it was ground before the experiments. The particle size of IIO after grinding was fine and uniform. The chemical compositions and XRD results of IIO are presented in Table 1 and Fig. 1, respectively. The results show that the iron oxide in ...

The size of iron ore affects the sintering properties. An increase in the size of iron ore promotes the productivity of sinter, but can reduce the tumbler strength slightly and save a little coke. The mineralogy of sinter can more easily be predicted from its chemical composition than its physical and chemical properties.
