iron ore. His process involved grinding taconite to remove gangues and upgrading the iron ore (, an ore beneficiation process). The resultant highgrade ore is in the form of fine particles, as small as or less, which are not suitable for sintering. This issue led to the use of pelletizing. Pelletizing plants are expected to play an

ABSTRACT Process flowsheet has a greater effect on equipment performance and operating conditions. For this purpose, performance of two iron ore beneficiation plants with the same equipment and feed characteristics but different arrangements in the grinding and classification circuit has been investigated. The first difference between the two plants was the screening type of HPGR product.

Beneficiation is the process where ore is reduced in size and gange separated from the ore. Since all iron ore deposits have unique mineralogy, the beneficiation process is specific to each deposit. Separation of certain minerals can be efficiently achieved by taking advantage of the physical, electrical and magnetic properties.
