Abstract

The current study is focused on the iron ores granulation process in a laboratory-scale batch drum granulator using water as a binder, and on the investigation of the influence of raw material properties (morphology and wettability of the primary particles) on its kinetics. Nowadays processing of iron ores often requires a modification of particle size by means of granulation in order to improve further processability. A comparison of the granulation behaviour of three types of iron ores (magnetite, hematite and goethite) has been carried out. The wettability of the powders has been characterised by contact angle measurement. The results confirm the hydrophobic and hydrophilic characters of magnetite and goethite respectively. The granulation kinetics (evolution of particle size distribution as a function of time) of each type of iron ores was measured.Peer reviewe
