    The iron-ore extraction curve is the average of the two curves given above. Recycling of iron follows a hyperbolic tangent curve from 30% to 90% recycling with a break point of year 1950 and width 50 years. The recycling is delayed by a Gaussian curve peaking at a delay of 25 years and a width of 10 years.

  • Which is the best variety of iron ore? Quora

    The coke does not reduce the iron ore directly, since solid-solid reactions are extremely slow. The CO reduces the iron ore, Fe2O3 + 3CO = 2Fe + 3CO2. The result is liquid iron, tapped from the blast furnace at approximately 1400C. This iron contains 4.2 wt% carbon, because that’s the saturation level for carbon in iron at this temperature.
