Deficiencies in the wet screening efficiency of an iron ore processing circuit were identified to be the result of biased loading of the screen decks from an upstream scrubber. An initial DEM model was developed to model the existing arrangement and to enable development and assessment of improvements.

Iron ore sample found is a part of banded iron ore formation. Hematite and goethite are major constituents of iron ore samples. Hematite in the ore sample occurs as specularite with inter granular micro-pore spaces. Goethite is profuse and occurs as colloform product in cavities in addition with the weaker bedding planes.

Introduction. Iron-containing ore beneficiation includes several stages. For example: crushing to. 30 mm size class and rough magnetic separation, further crushing of the recovered magnetic product to 10 mm size class and final magnetic metal content upgrading. All operations use dry methods.

The results of the analyses clearly shows that using a sieve of +180µm and its bottom -180µm, the best time for grinding 0.5kg of Itakpe iron ore with 3kg of grinding media and a mill speed of 92 rpm is 8 minutes, yielding 17.10% fines and 82.90% coarse., 0.8 mill critical speed measured 15.20% fines and 84.80% coarse.

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.
