    摘要: A process for desulfurization of gases with molten mineral baths during gasification of carbon products comprises the replacement of limestone or calcomagnesium materials by metallurgical slags, such as blast-furnace or steel-furnace slags, having a high basicity index. By means of this replacement, substantial savings in material and energy are achieved. Moreover, the use of residual slags for production of mineral materials that can be granulated and pelletized having good hydraulic properties, and pig iron that can be reused in metallurgical circuits, is assured.

    摘要: The process consists essentially of injecting into slags and cinders derived from the manufacture and various treatments of irons, cast irons, steels, and non-ferrous metals while they are molten and before or during cooling thereof, dry pulverulent mineral compounds capable of releasing non-polluting gases by thermal dissociation (metallic carbonates in particular). The easily fragmented slags and cinders obtained are usable in many fields such as: building and construction, ground coverings, abrasives, water filtering, fertilizers for agriculture, etc.
