Title
(EN) A METHOD FOR UTILIZING METAL OXIDE CONTAINING SIDE STREAMS IN FERROCHROME SMELTING PROCESSES
(FR) PROCÉDÉ D'UTILISATION DE FLUX LATÉRAUX CONTENANT UN OXYDE MÉTALLIQUE DANS DES PROCESSUS DE FUSION FERROCHROME
Abstract
(EN)
The invention is directed to briquetting metal oxide dusts and fine material with cement-based binders. After this the briquettes can be fed into arc furnaces for ferrochrome production through already existing inlet systems.
(FR)
L'invention concerne le briquetage de poussières d'oxyde métallique et de matériau fin avec des liants à base de ciment. Les briquettes peuvent ensuite être introduites dans des fours à arc pour la production de ferrochrome à travers des systèmes d'entrée déjà existants.
