Iron ore can be upgraded to a higher iron ore content through beneficiation. 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.

The opposite of saving energy is wasting it. Toss an aluminum can into the trash instead of recycling it, and the energy required to replace that discarded resource with new aluminum from bauxite ore is enough to keep a 100-watt incandescent light bulb burning for five hours or to power the average laptop computer for 11 hours, according to the Container Recycling Institute.
