Resumo
FeSn is a residue of the tin industry, which can be recirculated during processing of Cassiterite. A disadvantage of its recirculation is that it decreases furnace capacity, leading to lower tin production rates. Therefore, an optimization of the actual processing circuit can be related to the removal of FeSn from the system, which should be further processed in another equipment. As a first step toward a new processing route, characterization of alloys from different suppliers was performed through EDXRF, Metallography and SEM/EDX. Based on the results, a pre-treatment of the alloy and two possible recovery routes are suggested.
