Screening is an important step for dry beneficiation of iron ore. Crushing and screening is typically the first step of the ore beneficiation processes. In the majority of the ores, valuable minerals are normally intergrown with gangue minerals, so the minerals need to be separated in order to be liberated.

Rough processing of iron ore employs dry methods which means that equipment is tuned to process large particles, but fine magnetic material less than a few tenths of a millimeter in size is not separated as efficiently. The relevance of this study is determined by the fact that dry beneficiation waste contains recoverable ironbearing magnetite of commercial value.
