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.

Fig 3 Types of processing ores. The wet processing (Fig 4) is normally practiced for low / medium grade (60 % Fe to 63 % Fe) hematite iron ore. The wet process consists of multistage crushing followed by different stages of washing in the form of scrubbing and / or screening, and classification etc., but the advantage is only partial removal of adhered alumina and free silica in the CLO size ...

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.

A total of 6 parallel lines process 9500 t/h of ore. Screening equipment is installed after the primary crusher, after the scrubber and after the tertiary comminution stage to separate the iron ore into a dry coarse fraction (8 40 mm) and a wet fine fraction (> 1 < 8 mm). The fraction < 1 mm passes through another washing stage.
