How iron ore pellet is made – the pellets manufacturing process. Iron ore pellets are a man-made iron-riched ore. The pellet production method was invented in Sweden in 1912, and then began to be used in the United States in 1946 by shaft furnace. It was originally developed primarily for the efficient use of taconite mines.
