简介 Method for the production by thermal way of a concentrated solid - substantially iron free - enriched in contents of indium, germanium, zinc, silver, lead and possibly other metals, starting from the residuals generated in the zinc production chain, such as jarositic and/or goethitic sludge and/or mixed sludges from the zinc extraction processes by direct leaching, with the simultaneous production of an iron alloy with chemical composition from cast iron to alloy steel and of an inert product with physical structure from vitrified amorphous to crystallized ceramic. Figure 1 represents a simplified and qualitative block diagram of one embodiment of the method according to the invention.
