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 ...

High Pressure Grinding Rolls ("HPGR") are applied in all stages of iron ore size reduction, from coarse ore grinding down to pellet feed preparation. In closed circuit operation, fine grinds can be achieved using HPGR in combination with dry or wet classification or a partial product recycle without classification. For fine product cuts,

The Tecnored process is developed in Brazil. The process uses self reducing briquettes from iron ore and fine coal. These briquettes are cold bonded. Iron ore reduction in the self reducing briquettes is very fast. As a result Tecnored can limit the height of its reduction shaft and thus limits the mechanical load on the cold bonded briquettes.
