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. This chapter shows the status of the pelletizing process ...

A wide range of sensors has rapidly developed and advanced during recent years. Varied type of sensors has been utilized in the different steps of mining routes (Fig. ).Recently, in the processing plants, what has been getting more attention is using sensors right before the grinding units for eliminating the waste portion of coarse particles within a feed.

A considerable amount of test work has been carried out by Minerals covering dry grinding flow sheets, and further test work is in progress. The moisture content of pregrinding of fine iron ores, near 35%, could very well be handled and obviously would reflect the ore moisture as supplied to a plant.

When dry grinding is selected the moisture required for pelletizing must be provided either by wetting the ore and mixing prior to balling or by adding all the moisture in the balling device. To date only the balling disc has operated with a dry feed. Based on power consumed per ton of final product, generally the power consumption in the ...

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.
