Study Notes

ITMK3 is a process for producing iron and steel from iron ore fines.
It was developed by AMCI and the University of Illinois at Urbana-Champaign.
The process involves pre-treating the iron ore fines with a reducing agent and binder.
The treated fines are heated in a rotary hearth furnace to produce iron nuggets.
The process uses a thermochimney to promote efficient heat transfer and chemical reactions.
ITMK3 has a high thermal efficiency of around 70 to 80%.
The process has low emissions of greenhouse gases and air pollutants.
It does not require the use of coking coal, making it more economically viable and sustainable.
The high purity of the iron nuggets produced allows for the production of high-quality steel.
The process can be easily adjusted to produce iron nuggets with varying properties.
