Principle
This is a model experiment to show the industrial blast furnace
process to produce iron from iron(III) oxide. During the experiment
a furnace gas flame that is approximately 10 to 20 cm high can be
ignited at the stack outlet. Cavities form in the burning carbon
layer. These cavities collapse over time. Apart from ash and carbon
residues, metallic lumps can also be found in the frame after the
end of the experiment. Samples of these lumps lead to the formation
of hydrogen when they are treated with hydrochloric acid.
Tasks
- Investigate the reduction fo iron(III) oxide to Iron(II)
oxide.
- Show the blast furnace process in a model experiment.
