Iron Refining

The mined metal is pulverized and sorted. The best grades of mineral contain more than 60% iron. Lesser evaluations are dealt with, or refined, to evacuate different contaminants before the metal is sent to the impact heater. On the whole, these refining strategies are called beneficiation and incorporate further pounding, washing with water to buoy sand and earth away, attractive partition, pelletizing, and sintering. As a greater amount of the world's known supply of high iron substance mineral is drained, these refining strategies have turned out to be progressively critical.

The refined mineral is then stacked on trains or ships and transported to the impact heater site.
