Tin recovery and solidification of sludge from mirror grinding

Popis výsledku v původním jazyce

This study aims on tin recovery and solidification of mirror-grinding sludge. To extract tin from sludge, different hydroxide solutions (0.1 – 10M) are used. The sludge is also treated using the stabilization and solidification technique using ordinary Portland cement as a binder. Samples were evaluated using x-ray fluorescence analysis, leaching tests and compressive strength in the case of solidified samples. The results showed that nearly 57 % of tin was recovered as a precipitate in case of extraction in 10M sodium hydroxide. The 50 % of ordinary Portland cement was the optimal content for the solidification of sludge. The influence of active carbon addition into solidification mixtures was also evaluated. In conclusion, the mirror-grinding sludge was suitable for tin recovery, and its solidification resulted in nonhazardous waste.
