steel does not lose any of its inherent physical properties during the recycling process, and has drastically reduced energy and material requirements compared with refinement from iron ore. the energy saved by recycling reduces the annual energy consumption of the industry by about 75%, which is enough to power eighteen million homes for one year.
the ore extracted from the open pit is crushed in a gyratory crusher after being transported and stored in the crushed ore storage facility located within the processing plant site. the processing plant has a design capacity of 9 million tonnes extracted and processed per year, .
