The Pelletizing Process. The production of iron ore pellets from fines to finished product can differ based on a variety of factors. As such, it's important to note that the process described here is a generalized approach subject to many variations. In general, three primary phases occur in iron ore pelletizing: Mixing/Preconditioning

The configuration of iron ore pellets as packed spheres in the blast furnace allows air to flow between the pellets, decreasing the resistance to the air that flows up through the layers of material during the smelting. The configuration of iron ore powder in a blast furnace is more tightlypacked and restricts the air flow.

Another example has been presented by RioTinto, where the silica content in DR pellets was decreased from to under 1% through the implementation of silica flotation (Chaigneau 2015).However, the benefits of obtaining a higher iron content in the ore product must be weighed against the iron losses due to the separated gangue, the tailing grade and a property varying with the ore mineralogy.

Abstract The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking.
