The FIT is an innovative process that uses iron ore concentrate directly without further treatment. The fineness of the concentrate particles allows a very rapid reaction rate, thus requiring residence times measured in seconds instead of the minutes and hours it takes to reduce pellets and even iron ore fines. The FIT reduces iron ore ...
