A New Approach for Making Ferro-Alloys

Pages 409-417 | Published online: 18 Jul 2013
 

Abstract

A novel method of producing ferro-alloys by solid-state processing is described and the implications for producing ferromanganese are discussed. In its simplest form, this concept is based on forming metallic carbides directly in the ore matrix followed by standard ore dressing techniques to recover the product.

Inherent advantages include lower cost processing, reduced emission levels and use of coal as fuel and reductant.

Résumé

Une nouvelle méthode de production des ferro-alliages à l'état solide est décrite et les implications pour la production de ferro-manganese sont discutées. Sous sa forme la plus simple, ce concept est fondé sur la formation de carbures métalliques directement dans la matrice du minerai, à quoi font suite les techniques standard de préparation des minerais pour récuperer le produit.

Les avantages inhérents comprennent un faible coût du procédé, des niveaux d'émissions réduits et l'utilisation du charbon comme combustible et agent réducteur.
