    <description descriptionType="Abstract">&lt;p&gt;The primary iron metallurgy is characterized by significant direct CO2 emissions, due to the&lt;br&gt;
carbothermic reduction of the iron ore. This paper deals with the electrification of primary&lt;br&gt;
iron production by developing a new and innovative process for the carbon-free production&lt;br&gt;
of metallic iron from Bauxite Residue (BR) which is a by-product of the alumina industry. It&lt;br&gt;
is based on the electroreduction of iron oxides from BR suspensions in concentrated sodium&lt;br&gt;
hydroxide solutions, at low temperature and normal pressure. The iron oxide source, used&lt;br&gt;
in the present study is bauxite residue provided by Mytilineos S.A., Metallurgy Business&lt;br&gt;
Unit-Aluminium of Greece. The research study is a preliminary screening of BR as a&lt;br&gt;
potential raw material for iron production by performing experiments in a small-scale&lt;br&gt;
electrolysis cell. The first results presented here, show that iron can be produced by the&lt;br&gt;
reduction of iron oxides in the bauxite residue with high Faradaic efficiency (&amp;gt;70%).&lt;br&gt;
Although significant optimization is needed, the novel process shows great promise.&lt;/p&gt;</description>
