The hydraulic classifier "crossflow" was used to concentrate one iron ore sample between 0,15 to 1 mm size from the Sapecado MBR mine. The feed iron and silic contents were 60,19 and 11,81%, respectively. This equipment was tested in two ways: in the rougher stage and in Humphreys concentrate cleaning stage. In both cases it was possible to produce concentrates inside or near the commercial MBR product specifications.
