Abstract

Les résultats montrent qu'il est possible de minimiser la décomposition par réduction de minerais de fer et d'agglomérats dans chaque cas grâce à des halogènes, respectivement à leurs composés chimiques. Le degré des améliorations dépend de la concentration puisque la quantité d'agent actif introduite dépend proportionnellement de celle-ci pour une même quantité de solution absorbée. En outre, la nature du réactif a son importance, étant donné que ces hautes fractions stoechiométriquement différentes contiennent des halogènes. En règle générale, plus la diminution de la décomposition par réduction est forte, plus la concentration de la solution est importante. Afin de n'introduire dans la solution que le moins possible d'éléments chimiques, il faudrait déterminer pour chaque lit de fusion la concentration la plus petite possible.
