What is iron ore beneficiation? - Shandong Jiugang Tisco Steel Co., Ltd.
Iron ore is an important raw material for steel production enterprises. In most cases, iron ore with a grade of less than 50% requires ore beneficiation before smelting and utilization. Natural ore (iron ore) is gradually selected for iron through procedures such as crushing, grinding, magnetic separation, flotation, and gravity separation.

Iron ore pelletizing - Outotec
This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which don't need beneficiated, fines which are generated can be pelletized and used instead of being disposed of. Iron Ore Pellets are formed from beneficiated or run of mine iron fines.
