Abstract

GURGEL, Hely Simões; LIMA, Rosa Malena Fernandes  and  OLIVEIRA, Maria Lúcia Magalhães de. Concentração de itabirito silicoso da Mina do Sapecado/Complexo Pico - MBR, empregando o classificador hidráulico de fluxo transversal "crossflow". Rem: Rev. Esc. Minas [online]. 2006, vol.59, n.3, pp.335-339. ISSN 0370-4467.  https://doi.org/10.1590/S0370-44672006000300014.

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.

Keywords : iron ore; gravity concentration.
