iron ore pellet production process
Iron ore pellets for blast furnace a technical guide.
How iron ore pellet is made the pellets manufacturing process. Iron ore pellets are a manmade ironriched 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.
