effects of iron ore particle size on the quality of pellets

Effect of Fluxing Agents on the Quality and Microstructure

Indian iron ore fines with high alumina content (~2.5% Al 2 O 3) resulted in poor quality pellets and a study was under taken to establish suitable pellet chemistry through proper fluxing agents. Limestone fluxed pellets were prepared at varying basicity (0 to 0.8) and pyroxenite fluxed pellets at varying MgO contents (0 to 3%) to study their effect on the metallurgical properties.

Effect of iron ore-coal pellets during reduction with

Pellets of size 15 mm were made from 1.5% bentonite binder and iron ore–coal mixture in a disk pelletizer (diameter = 1000 mm, rotating = 24 rpm, angle of inclination = 45°). The pellets were dried in an oven at 110 °C for 2 h before experiment, and these pellets were isothermally reduced at 700–1100 °C under reducing atmosphere with a flow of 0.5 L/min.

Hence properties of the pellets are largely governed by the form and degree of bonding achieved between the ore particles and the stability of these bonding phases during reduction of iron oxides. Since the formation of phases and microstructure during induration depends on the type and amount of fluxes added, there is an effect of fluxing agents in terms of CaO/SiO2 ratio and MgO content on the pellet quality.

Effect of particle size on reduction behavior in iron ore

The reduction of iron ore-coal composite pellets was carried out in the temperature range of 500 ~1200°C by thermogravimetry. This study aims to investigate the effect of particle size of iron ore on reduction behavior. Three samples of different particle size were selected: 25 ~48 µm, 75 ~106 µm and 150 ~180 µm. The reaction kinetic parameters were estimated based on the thermogravimetric data.
