1. Direct reduction principle
This reduction, or rather, deoxidation of iron ores, i.e. iron oxides, must be examined from the following four points of view:
the stoichiometric aspects of the corresponding chemical reactions, which will give the theoretical requirements of all the reagents and, in particular, of the reducing agents;
the thermochemical aspects of these same reactions, which will lead to theoretical energy balances;
the equilibria established in the reduction of iron oxides by gases;
and the kinetic aspects of these reactions.
1.1 Stoichiometric aspects
This first and simplest point of view will enable us to determine...
